Costco Specifics

Costco is one of the most popular retailers because they promise lower prices for members on common goods. That said, not everything bought at Costco is a great deal. Even though things like toilet paper, paper towels, and bulk food products are better to buy in store, when it comes to mattresses, there is a little known truth:

Buying comparable products on sale in other retailers may actually be cheaper.

Although this isn't the case for all products, there is a case for going direct to the manufacturer or haggling with local retailers who are willing to budge on price. Also, even though Costco often licenses their own designs for their members, a second hidden truth is:

The Costco selection may not include the right mattress for you.

Part of the reason for this is Costco is focused on the lowest common denominator when it selects its products, and possibly not the unique individual comfort that you may actually need.

If you are interested in getting a long-lasting mattress that feels great to you, learn what sleepers are saying about our top rated mattresses or our top rated mattresses for the money. Read on to learn more about Costco's mattress offerings...

Costco has a few relationships with some nationally recognized mattress brands, such as Tempur-Pedic, Sealy, and Simmons Beautyrest, but even though these are household names, they aren't always the best for you. We'll go through the mattress brands being sold at Costco and discuss which may be best.

Here they are ranked...

#1 Ghostbed
Ghostbed is a popular online mattress brand that offers both all-foam and pocketed coil mattresses. With options that range from medium to medium-firm, they are ideal for those looking for universal comfort. With cooling layers on the surface of their mattresses and the addition of edge support in their hybrid models, there is a lot to love about this brand. However, Costco does not offer some of their highest rated options sold direct. Additionally, there are some reports of a better sleep trial and customer service buying direct.

The pros: Well-rated brand with better rated pocketed coil options.

The cons : The newer products are only available direct through the brand currently.

Price Range: $649-$3499

Final Score: 9.1 / 10

#2 Tempur-Pedic
Tempur-Pedic is one of the most common household names when it comes to memory foam mattresses. Although the selection is not as wide at the Costco warehouse stores as in other locations, Tempur-Pedic is synonymous with high end foams for a high end price. Although some folks are heartset on owning a Tempur-Pedic, there are plenty of less costly options that you can buy direct: such as our top memory foam mattresses. With that said, Tempur-Pedic is still a good brand with a good reputation.

The pros: Good range of memory foam products for a competitive price point vs other retailers.

The cons are that the selection is not as wide and there are no Twin or Full versions at Costco.

Price Range: $1099-$3399

#3 Brentwood Home
Brentwood Home offers a variety of eco-friendly memory foam and pocketed coil mattresses. In terms of their directly sold offerings, they have begun only selling certified GREENGUARD Gold mattresses, which is one of the most rigorous emissions and low-VOC standards and a great innovation for their products. However, at Costco, there are some differences with what can be purchased versus buying direct. Costco stocks some lower priced and in some cases, older models that may or may not be as rigorously certified. While most customers like these offerings, there were some differences in customer feedback with some customers having issues with durability.

The pros: Good deals for the brand found at Costco.

The cons: Some lower priced models sold at Costco have lower ratings than those sold direct.

The Leesa Hybrid is 11'' thick with a firm / medium firm feel while the Legend is 12'' thick with more of a medium to medium-soft feel. Overall, while many customers enjoy their Leesa mattresses, their were some disagreements with the firmness level as well as some mention of heat retention.

Purple is known for creating mattresses featuring their proprietary Purple Grid, a gel polymer layer that adapts to your body while allowing for air flow. Costco carries an exclusive Purple mattress, the PurpleRenew, which is an 11'' thick, all foam mattress available for a more competitive price than Purple's direct offerings. While the PurpleRenew might be a more affordable way for sleepers to experience the Purple Grid, it won't have the newest technology available compared to Purple's direct mattresses. Some customers have also brought up disagreements with the comfort, support, and smell in some cases.

The pros: Competitively priced option for Purple's mattresses.

The cons: Some have mentioned issues with support and feel.

Firm and comfortable

I waited over a year to write this review, as it took quite awhile for me to adjust to this mattress. I am a problem sleeper, having suffered from insomnia most of my adult life and also have lower back issues (I'm 62, 6' and athletic 195#). This is my third mattress in 5 years. It has proved to be the best one for me. It is very solid, firm bed but with enough cushion to keep you comfortable. You do not sink in as with memory foam. I can sleep in all positions with no issues whatsoever. It has held up well thus far; no indentations or edge breakdown. The only problem is that when I travel, no mattress is as firm or comfortable to me as the Novaform. Thank you COSTCO!

Great Mattress

We needed a new mattress, so I researched them starting with Consumer Reports, which rated this their top foam mattress. This is our first foam, so I really didn't know what to expect. Also, we have never purchased a mattress without first trying it out in a store. It arrived quickly and was fascinating watching it expand after to cut the plastic off it. I have to say that it's harder than I expected, but I am getting used to it after two weeks. My wife, who sleeps on her back, is sleeping noticeable better. There's also no movement transferred to the other person, which is a good thing. Neither of us noticed any unpleasant smell as some have reported.

Reasonably priced, Super comfortable!

In the interests of full disclosure, our previous mattress cost $300 new. So maybe we're just easy to please, but we absolutely love this mattress. It's firm, but not too firm. It's great for back and side sleeping. I am pregnant and finicky about sleeping, but I've been very comfortable. I was (before the pregnancy) 5"4 and 130-ish lbs. My partner, who is 6'2 and 225-ish lbs, also finds it very comfortable.

Better for stomach and back not for Side sleepers

My wife is a stomach sleeper and i am a back and side sleeper. i've owned this medium to firm mattress for 11 months now so i got a good hang of it. I wake up with joint pain, lower back pain, shoulder pain and toss and turn all night. the mattress has good construction and build quality. my wife complains less then i do because this mattress suits her better. however, my inlaws who bought the same mattress have similar complaints to mine. I am thinking of replacing this king mattress with two twin xl mattresses so my wife and i can individually pick the right firmness without breaking the bank on a sleep number bed.

Great especially compared to more expensive brands

We were amazed at how small it gets compacted down to for shipping. As soon as we opened the box and cut the straps it unfolded into a king sized mattress right before our eyes. I feel that it is a medium firmness despite some others saying it was harder. If you had a spring mattress before then you might not be used to the way a foam mattress feels when you first get on it. With a spring mattress you do bounce a bit. With the foam it seems to just dull any kind of bounce but then it envelopes around you. I am a side sleeper and this has been a great for that. I can't say there were any miracle sleeping improvements but it is very comfortable and I am satisfied with my purchase.

Love, Love, Love My New Mattress

I was a little hesitant about buying a mattress online without ever trying it but I am so glad that I did. After reading Consumer Reports reviews on this mattress and with the great return policy that Costco offers, we decided to take a chance and I am so glad that we did. This is by far the most comfortable mattress I have ever owned. It was comfortable from day one and have never slept better. No more waking up with a stiff back or neck. Can't recommend this mattress enough. Love it so much that we will be buying a second one for my son. Thank you Costco and Novaform!!

Best Value on Market

I bought the previous model of this Serafina mattress two years ago and really liked it. Then we bought this model. (I think this model has a different top to it). Nevertheless, I absolutely LOVE this bed, especially for the money you pay. We also have a $3,000 Tempurpedic and a top-rated Sleep Number, so we are in a position to compare. This bed beats them all hands down. I wake up each morning refreshed -- no turning through the night. That new top really works, I’d say. With that, I am a side sleeper with a little stomach sleeping. So if that is you, I'd highly recommend this mattress.

Good support but too hot to sleep comfortably

This mattress has very good support for both side and back sleepers. I sleep like a rotisserie turning all night long and this mattress provided good support and kept my back aligned in all positions. But it retains your body heat and it gets hotter and hotter throughout the night making it very uncomfortable. I found myself moving from one spot to another to keep comfortable. I tried various mattress pads but nothing alleviated the body heat it retains and gives back (without a pad was the worst). As the summer nights got warmer the resonating heat has become unbearable. The gel beads are supposed to provide "ideal sleep temperature" but it seem to be just marketing talk.

Horrible Mattress :(

I did my research and read all the reviews. Most sounded good and that we would give this one a try. We are in our 60's and have been sleeping on a memory foam mattress with pillow top, but it very old and there is no support any longer so we needed a new mattress. Bought this one online and tried it the first night. My husband complained it hurt his back, but we both decided we'd try it again. He has not been able to sleep on it since, and I have been using it for 5 nights now, each night being worse and waking in more back pain. So today it's going back to the warehouse and we have already tried out and purchased a Sealy Perfect Sleeper! This supposed "medium" mattress is hard as a rock.

Highly Recommend

I brought this a month ago after waking up with aches and pains from sleeping on an older mattress. I was hesitant to buy a mattress online, but decided to go for it. It was a very easy setup but I was not happy that there were no handles. However, I've since learned that the new mattresses are not being made with handles due to the size and weight. It took a few nights to get used to the feel, but what a difference it has made for me. I used to wake up and get out of bed at 3 am because of feeling achy. Now, I leave the house late almost every morning because I don't want to get out of bed. It may not be the same for everyone, but I'm very happy with this mattress.

This mattress IS top rated by CR.....

So I've read through a ton of reviews here on this mattress and many have stated that the Pearl Gel is not the same mattress that Consumer Reports initially reviewed and that this newer model does not show up at all in their ratings.

The Perfect Mattress

We love our new mattress. It was rated #1 on consumer reports for memory foam mattresses! It isn't hot at all like some people say memory foam can be, and it's not hard either. This one is rated a medium firmness and I believe that's accurate. Also, when you set it up, no smells at all, but it will take a full day or two to be fully expanded. We slept on it about 4 hours after setting it up and I was worried it was too soft but that was only because it hadn't expanded fully yet at all. I can also sit on the edge of the bed and not slide off because it doesn't compress too much. Stop thinking and buy this bed!

One year later: Back & joints sore

Initially, I was sleeping pretty well on the Novaform 14" Serafina Gel Queen Memory Foam Mattress although my wife thought it was too hard from the start. After a year of sleeping on the mattress, I must agree with her. There is very little "give" to this foam and my back and joint pains returned after a few months of relief. (Imagine what the innerspring monster was like if this gave me relief when switching). We are moving this mattress to the guest bedroom and getting a medium soft mattress. The firmness scale should be a standard item in features or description sections.

Glad I bought it!

Went to several mattress stores, including the one with the "system" that determines the right mattress for you. I kept returning to this mattress and, after reading the reviews, decided to try it. I've had it now for more than six months and am completely satisfied. Initially, I wondered if it would be too firm but the firmness is not the same as sleeping on a solid flat service. I would describe it more as "supportive." I live in a hot climate and am not uncomfortable. It is not a hot mattress, in my opinion. I'm a side sleeper and do not wake up with back pain.

Sleeping soundly, again!

Very happy with this mattress. A great feature is my wife does not feel me toss and turn / or get in and out. She is a light sleeper and slight movements wake her. On another note, COSTCO and Innocor are great to work with. We had a NovaForm mattress for about 7-8 years, and recently noticed deformation in the mattress which we believed to cause lower back pain. While we had misplaced the original receipt, COSTCO quickly retrieved this when asked. The Innocor Rep (Carmen) was a pleasure to work with on our warranty claim. They stand behind there product and shipped a new unit to us in short order.

Love this mattress!

I've been sleeping on this mattress for a year after sleeping on spring mattresses for the past 50 years. I love this mattress. It did seem a bit firm for the first month or so but over time both my wife and I have noticed a very nice adjustment to a medium feel. I am 5'9 180 pounds and this mattress has eliminated any back pain I felt in the past on the spring style mattresses. I sleep around 50%+ of the time on my side and coupling with a correct pillow(s) is very important so I recommend investing in both a good mattress and some nice pillows to get the best sleep outcome.

Great Purchase

I bought this mattress about 2 months ago and it's wonderful. I had been reading a lot on consumer reports for many different mattresses, and this one seemed to have the best qualities for the price. It has one of the highest ratings overall, as well as some of the best ratings for a foam mattress for spinal support and durability. There was definitely a break in period for about a week, but now I'm sleeping so soundly and not waking up at all during the night (which I used to do all the time). It is medium firmness as described - very good for your back!

Deserves 10 stars!

For years we wanted a Tempurpedic so when offered them a couple of months ago, we took the plunge. For six weeks, I did not sleep. The Tempurpedic was hot, hard as a brick, and uncomfortable. It was also excessively tall.

More than satisfied so far

I'm a researcher and looked for a couple months before deciding on this mattress, based both on reviews on here as well as it being a Consumer Reports best buy. I've only had it up for 3 nights, but we have both slept more solid in the last 3 nights than we have in the last 3 months. We are both average sized people and find the "medium" rating to be slightly off, but it's been exactly what we wanted. This was also one of the reasons I purchased this particular one because other reviews had said it seems more firm than what a medium should be. If I had purchased a firm, I'm guessing that would be too hard. Everything this mattress advertises other than firmness is accurate, so hopefully this helps you decide. I will update this review down the road after we've been on it awhile.

Good if you like it firm

I slept on this bed for 2 months and then returned it. I returned it because most days I woke up with a back ache, it was too firm for me. They say it is medium firmness, but I don't agree. I would rate it at medium firm. Firm to me is like sleeping on a board, and it is not quite that bad. Weird thing is, I had no problem falling asleep or sleeping, just I always ended up on my back rather than my side where I started and most days had an achy back. I had no complaints about the quality. It is very heavy when it comes, and definitely needed help getting it to the second floor.

4 hours later and you're sore

I really wanted to like this product. The Consumer Reports review is positive, as are many end user's reviews. When you first lay on it, it feels OK. 4-5 hours later, as the top foam layer compresses, you end up on the harder main foam block. It's like putting a memory foam topper on your driveway and sleeping on that. I noticed most all of the negative reviews complain of it's hardness, and most report pain or soreness. I am no exception. In fact I wake up due to the discomfort and notice tingling in my arms or fingers when side sleeping. I cant figure out if its just such a wide variation in personal preference that explain the reviews or if there is variation in the foam that yields mattresses with variable characteristics. BTW, I'm 6'0 and 190 lbs.


I purchased this mattress for my guest bedroom, but it's not budging from my bedroom! It's so comfortable, I've been sleeping like a baby since it arrived. It was extremely heavy! I live in a second floor apartment and my sister and I struggled to get it up the stairs. I mean pushing, shoving, pulling, panting! We are mid 50's to 60, so, I don't know. Once opened and on the bed, it quickly turned into this luscious Mattress before our eyes. It did have a smell, but it quickly dissipated; I was able to sleep on it first night without any foul smells. It's high quality, more on the firm side, but my husband and I like a more firm mattress. I would absolutely recommend this mattress! I Love it!

Comfortable and precisely medium softness

I don't know why some people are saying this mattress is too firm. If you hop around beds at mattress outlets, you'll see that it is precisely a medium-softness mattress. This is my first foam mattress, as I've always slept on the old fashioned spring coils. And as a hot sleeper, I'm wary of the reputation foam has for retaining heat. The gel in the mattress is supposed to keep you cool, and it definitely does! Sometimes that cooling effect can wear off within a month or two though, so I guess we'll see! But in the meantime, this is the most comfortable mattress I have ever owned, and it is comforting to have the Costco name behind it.

First time memory foam mattress owner

After years of suffering through restless nights sleep on our coil spring mattress we decided to try a memory foam mattress. We read about this top rated mattress on Consumer Reports online and it has surpassed our expectations tenfold. We have been having our best night sleep in ages and have been waking up feeling completely rested and ready for the day. I have told all of my friends and family about our purchase and recommend this mattress to anyone out there who has never tried a memory foam mattress or just wants a restful nights sleep. We will never go back to a coil spring mattress and look forward to going to bed every night now. This is by far the most comfortable mattress I have owned and I never imagined I would feel this rested in the morning.

Best mattress we've ever owned

I've been looking for a mattress to replace a 10+ year old box spring mattress for some time. After seeing the reviews for the Novaform Serafina mattress I decided to take the plunge. I've waited two months to write up a review to make sure it was as good as others said. I am definitely happy with the mattress. It has helped my aching 60 year old back. That was the main reason for the purchase. The only problems I've had are slight smell for 3-4 days and it was firmer than I was used to. After two months I think the firmness is a plus. I was also worried about the top layer of foam indenting, that has not been a problem.

Not your conventional foam mattress.

We've had our Serafina Pearl now for about 3 months, having replaced a 10 year old pocketed coil mattress. I liked the fact that I could move around and not disturb my wife with the old mattress and this one does as well at that, if not better.


Consumer Reports was spot on. This is by far the number one mattress I've ever slept on. When you first get in bed the mattress seems a little firm but then you sink in the perfect amount for total body support. When you spouse move you don't feel any movement like with a spring mattress. Probably the only low spot is that it's hard to sit on the edge of the mattress. In my case it doesn't really matter because mine is a platform bed with drawers underneath so it's too high to sit on anyway. Absolutely love this mattress and the price was great.

Wise purchase

After reading others' reviews as well as a well know consumer magazine's rating, we chose the Novaform Seraphina mattress. It is a great value being at least one third the price of similar mattresses. It did not smell at all the first day and inflated well over the day, so we slept on it the first night. We have had it a week are are very satisfied with its comfort. It is firm but cushions and does not let you sink into a "hole." My husband says his shoulder doesn't go to sleep any more and he is less restless at night. I am also aching less and sleeping better. Even though we couldn't lie on it before purchasing, Costco's return policy is so fair that there is basically no risk.

Buying this mattress is like playing lottery

We needed two mattresses, so I bought one to see if we would like it. We liked it a lot, it was of medium softness as stated in the description and very comfortable. Within several days I ordered the second one and it turned out to be hard as a rock and impossible to sleep on. If I did not know I would think these two mattresses were two different models. I am returning it and wondering if I should order another one and see if I get lucky or just buy a different model.

I plan to die on this mattress

I have purchased over 10 mattresses in 20 years. At first I focused on the mid range priced mattress, like Sealy or Serta, but they did not work. Then I decided I needed to pay for a good mattress, purchasing a Sterns and Forster which cost over $2,000. No good. I then just picked up a cheap one at the local store because I was tired of buying the wrong mattress. I have had 2 back surgeries and worried about not "trying it out" but pulled the trigger on the Serafina. I plan to die on this mattress!! I will never mattress shop again as this is the best!

Best Mattress I've ever slept on

I don't write a lot of reviews, but I thought I would this time to counter the negative reviews about the mattress being too firm. First, the mattress is firm, but not "too" firm. Second, I have arthritis in my back and can't get a full night’s sleep without experiencing aggravating pain that sometimes keeps me up at night. I bought this mattress because it was top rated by consumer reports for back and side sleeping. The first night I slept on this mattress, not only did I wake up pain free for the first time in many years, but I actually overslept because I was so comfortable! I have to admit, I was a little scared of the firmness at first because I like a soft bed, but I’ll take a firm mattress that’s good for my back any day over a soft mattress that causes back pain.

Cool and Firm; Serafina Memory Foam Mattress

This was a replacement for a 5 year old Queen Memory Foam Mattress; that was older generation technology. This Mattress is much cooler and breathes better, than the older mattress, due to the Gel Pearls in the top layer and the CustomWave foam in the 2nd layer. The Novaform website indicates the feel of this Mattress is MEDIUM, however after over a month sleeping on it, it feels more FIRM but still comfortable. This mattress replaced a memory foam mattress that cost 125% more 5 years ago without the newer technology and today costs 162% more with similar newer gel foam technology. Costco still gives you more bang for your buck!

Love It!!!!

My husband & I had never slept on a memory foam, so, we were hesitant to go this route, despite Costco's fantastic guarantee & price. Our old mattress had to be replaced because I'd developed lower back pain for no apparent reason. After a lot of online research & visiting several stores (what a shock the prices there were!), we decided this would (hopefully) be for us. OH MY GOODNESS!! We slept on it the first night, had no trouble rolling over, or keeping our bodies comfortably cool. I slept the night thru, & woke up PAIN FREE!

So Comfy!!!

I was looking for a new king size bed and started with Costco. The great reviews attracted me to the bed though I understand that everyone has a personal preference when it comes to mattress softness/firmness. I thought about it for a few days and then placed my order. Of course Costco shipped it to me for free which was super convenient. The bed arrived in a super heavy box so it took two of us to bring it up stairs. Once we took the wrapping off the bed quickly puffed up to it's normal size. There was no odor what so ever which really pleased me. The bed is a perfect combination of softness yet firm enough for good support. This has been the most comfortable bed I have ever slept on! Better yet, you won't feel it when your partner moves in the middle of the night!

Know your personal mattress preferences first

We purchased this mattress based on reviews and a lot of other online research. I LOVED the mattress. My hubby, however, found it to be TOO firm. He has a hip prosthetic and was unable to lay on that side because the firmness caused him pain. It is firmer than the air-style high priced mattresses at firmness #10. We had to return it. YAY, COSTCO! We called for a pick-up. Done. Seamlessly. No added cost. My family doesn't call me "Costco Diva" for nothing! Costco service is unsurpassed.

Firm is an understatement

This mattress is firm ... Very firm. I was replacing a memory foam mattress and thought I'd try this brand. It does not even have the feel of a foam/gel mattress. We slept on it for 3 weeks waiting on it to "break in." It never gave a bit. I like a firm bed, but this was too firm for even me. So just be aware that it is extremely firm with little to no give (as a memory foam mattress does). If you like a mattress with a "board" feeling, this is the one for you!


BUYER BE AWARE… if you are thinking of buying a mattress by Brentwood on there is something you must know. You can call Costco Customer Service and ask what their return policy is. They will quickly tell you, “Never fear… if you don’t like the mattress we will pick it up and refund your money.” That is NOT totally true. I bought a Brentwood mattress for my dad in assisted living. It was supposed to have great edge support due to being a hybrid. It does NOT and he can’t stand up when sitting on the edge. When I contacted Costco to pick up the mattress they sent the pick up order to DM Transportation who says they do NOT service the town my dad lives in, even though it was delivered there. I called Costco. They told me that I MUST be patient while they work through this problem. They do NOT have their own transportation service. The VENDOR handles the return pickup. I told Costco Customer Service this is NOT what Costco Customer Service tells people when they ask about the mattress return policy. They do NOT say, “It all depends on whether the VENDOR services your area.” I have it in writing in a chat that if I have to return this BRENTWOOD mattress that it WILL be picked up and it does NOT need to be repackaged or reboxed. I AM VERY UNHAPPY THAT COSTCO IS NOT PICKING UP THE SLACK AND STANDING BEHIND THEIR “NO HASSLE” MATTRESS RETURN POLICY. I GOT ATTITUDE FROM THE SUPERVISOR AT COSTCO CUSTOMER SERVICE. Today I contacted Costco Corporate Customer Service. They promised me it would go straight to their Escalation Team and someone would get back to me asap, but no later than 24 hours. I heard nothing today. AGAIN, I GOT ATTITUDE. I was told do NOT call us back every two hours like some people do. I tried to explain that I need this mattress picked up ASAP because my dad has dementia and the mattress is leaning against the wall and he will mess with it, try to move it, and possibly hurt himself. I was told to save my additional information, they don’t need it. I’M APPALLED!

Sealy West Salem Cal King Mattress/Foundation

I Don’t care for the gel mattress top. It’s very comfortable but your body does tend to sag into the mattress. I was hoping it be a little better quality

Super comfy firm bed

Sealy West Salem mattress is firmer, but I like it. It doesn’t feel as firm as you might think. I bought this after getting a boxed mattress and disliking it due to quick sinking of one side. This was the same mattress I slept on at a friend’s house and had the most amazing night of sleep on, so I felt confident getting it. Me likey.

Quality and comfort

Really pleased with the quality and comfort

Great for lower back pain

Sealy West Salem is a very good mattress for lower back pain. It took a few weeks to get used to sleeping on it as our old mattress was a pillowtop. This mattress has great support for back and side sleepers. I have no more lower back pain when I wake up. Good quality.

Sleeping through the night wake up feeling great.

Great firm support for a heavy man. Sleeping through the night wake up with no bad achy back. My previous mattress cost $250 more and was hideous threw it out after only two years.


Love our new mattress!! This Sealy West Salem is the perfect mix of firm and light cushion. The posturepedic provides exception comfort for a great nights sleep, we will never go back to another mattress. Also appreciated it was delivered in 3 pieces to easily move and set up.

Excellent mattress

Coupled with a solid frame bed (no box spring)- the West Salem mattress provides excellent support and comfort. My guests have had "the best sleep in too long" on this mattress- they have purchased one as well.

Delivery and quality

Very comfortable and firm. Costco delivery was and removal of old mattress were quick and convenient.

Very good mattress

I like the Sealy mattress a lot. Solved all my back issues. Only a 4 because it’s not Goldilocks perfect. It’s very firm, soft enough but not luxuriously so. No complaints tho. Just describing how it feels.


Perfect mattress for second bedroom. Depending on your frame you might need a mini box spring to raise it up

Firm cushy mattress

Couldn't be happier firm yet cushy from the memory foam. It was a bit higher than expected but we are okay with it.

We would do it again!

The two mattress' we received were as advertised. Comfortable, proper firmness, and very well made.They were manufactured to order and relatively local to us was a big plus. My wife and I have no regrets on our purchase. The delivery and pickup of old mattress' was also first class, very sanitary,.and timely.

For firm mattress lovers

We bought this Sealy mattress solely on product reviews. If you like a firm mattress, one that doesn’t sink in, this is for you. What we were quite angry about was shortly after,within 24 hrs of getting our mattress delivered, you were offering the SAME mattress for $100.00 less. Not nice!

Great product

Great quality mattress. We purchased 2 and couldn’t be more pleased

Great mattress

Great firmness for lower back pain

Not Happy

Not happy with the quality of this Sealy West Salem mattress. The mattress is not firm as advertised. I even confirmed this with a call to Costco online representative before purchasing. Already sagging and way too soft. Will be returning this mattress.

Very Firm

I thought that based upon the average star rating that this West Salem mattress would be pretty good and I decided to ignore the negative ratings, just figuring that I fall within the majority of people. I was very wrong. I ended up buying this mattress on sale in the store for a great price. I normally like a firm mattress, not extra firm, but medium firm and this didn't quite do it for me. I actually purchased this for my daughter and before she got a chance to use it I had my mother stay over for a few nights to use it and also my husband and both complained how uncomfortable it was. My husband can sleep on almost anything and the fact that he complained was not a great sign. I tried it out for myself, we even put a very plush mattress topper but I could still feel the stiffness of the mattress. Even when I pressed down on it it felt like there was a hard cardboard piece. We ended up returning it, I could not imagine my little daughter using this for years knowing how uncomfortable it is.

Sagging mattress despite turning

Bought this West Salem mattress and it literally started sagging within 4 months. We've turned this mattress at least 20 times, and now there's a hump in the middle between my husband and I, while where we lay has a huge dip. I really wanted to like this mattress because it was pretty comfortable at first. But this one has to go, and my next mattress will not be a Sealy if this is the quality they are putting out.

Great Price

I was a little worried placing this order right in the middle of this corona virus pandemic and worried that the West Salem matress would be too firm. To my surprise the order was delivered in a timely manner and the matress was very comfortable. I was afraid we might need a matress topper.

poor back suppot

I bought this West Salem mattress in the end of January and I started using from March 2nd as was in vacation in between, while purchasing I thought it would be good for back support but it is not, this feels like normal spring matress selling with brand label SEALY, Not at all happy with performance

Premium West Salem Cushion Firm Cal King Mattress

Arranging the delivery could have been smoother but other than that the ordering and actual delivery went well.

firm but not firm enough

overall we are quite satisfied with the west salem mattress, we feel that the mattress is too soft to be classified as 'firm'. our previous bed (we kept for 29 years plus) was also firm but somehow was much firmer than this. not a problem, we are keeping the mattress.

Not good for us :(

This West Salem bed is so stiff there is no way we can comfortably sleep on it. We've kept it a month and are currently returning it for the plush because it's just way too hard!


Although it says FIRM, it's more of a pillow top and makes it feel very soft. Not a good back support. Will be returning.

Great purchase!!

Great purchase!! We sleep so so comfortable.

Very comfortable

This is the second purchase we have made for the sealy west salem mattress. This set went in our spare room.

One of the Best Mattresses I've ever owned!

The sealy west salem mattress is one of the best mattresses that I've ever owned. Perfect firmness for back support and side sleeping. I compared this price with other stores and it was about $1,000.00 cheaper than a lower-level Sealy mattress at Sit N' Sleep. The Delivery and Set-up was impeccable! I highly recommend this mattress.


Looks like im getting this matress when corona is over.


Good night sleep the first night

Beautiful & Comfortable mattress with base

Beautiful comfortable mattress. The exposed part/sides is a material it all is a darker grey color that blends with any decor and doesn’t require a bed skirt for the matching base. Highly recommend.

Perfect level of comfort

A great mattress for side sleepers

New Mattress Arrived

After years of trying new mattresses from the most expensive, then even a sleep number, dual control, etc. (AKA. Way to hot) then back to the basics. My wife asked me to just go back to the basics, you have nothing to loose but more sleep. We tried this Beautyrest Medium Firm mattress and could not be more pleased with the results. the very first night, I did not get up because I was too hot. Woke up rested, relaxed, younger. I did not know that my 2year old mattress was causing so much of my daily back pain and inability to sleep. This mattress is the perfect firmness for me and cradles my body with support on my back or on my side. I sleep peacefully on this mattress. The delivery was easy and awesome to setup and they arrived on time. This mattress is a keeper. Thank you. Now taking the sleep number to be recycled at goodwill.

Very comfortable

I haven't had it for long, but as other reviewers have mentioned, this is pretty firm, but I love that. Keep in mind, the delivery guys (two of them) won't carry it upstairs for you. I'm in pretty good shape, but I couldn't get it upstairs by myself. I needed to recruit two kids to help me. Teens. Hopefully the delivery company adjusts their policy to carry this upstairs. It would've been much easier for them to just put it in it's place.

Box spring and mattress

Product delivered was as described. Very comfortable. Would order again if needed

Rock Hard

THis was a beautiful mattress; however, it was too hard for my husband and me. We woke with backaches for the first 3 mornings we had the mattress. Unfortunately we decided to return it. THe return was hassle free and an easy process for us. Great customer service!

Very good so far!

This mattress is definitely pretty firm, and I thought I may have made a mistake when I moved my $2400 mattress out and noticed how much lighter this one was to move into the bedroom. But once I got it on the box springs, I could tell the quality was good. I’m still thinking of adding a thin foam topper if I can’t get used to the firmness, but for now I’ll wait and see. I would recommend this mattress, especially compared to the over-priced ones that are out there.


Very comfortable.

Value for money

The mattress is comfortable and meets our expectation

Comfortable firm mattress

The mattress is firm but soft very comfortable & thick enough. Very glad to have ordered it

Broken box spring

Product came broken. Was unable to get through to customer service.


This bed is supposedly a medium firmness, but it feels very firm. Could not sleep well on this.

Perfect mattress!

Perfect firmness, and on time delivery. Thank you!

Beauty rest Silver Queen Mattress Set

Great quality!

Great price for a great bed

It’s great! We donated our purple mattress and bought this mattress.

Horrible service

I am extremely disappointed in Costco’s subcontracted delivery service. I orders the California King Matress and box Spring set from Simons Mattess. I signed up to get a text message when the delivery truck was 30 minutes from my house. The delivery windo stated between 2pm-6pm. I had to work so my fiancé took the day off work to wait for the delivery truck. They arrived approximately 10am. Left my matress and box spring on the porch and drove away. My fiancé told me they didn’t even ring the doorbell, just dropped off outside on front porch and left. I called back 5 times and complained to 2 different employees at the dispatch center. Both were useless. Both states to me we can’t get a hold of the delivery driver and we will have someone from their hub call you. It is now a week later and no one has called me or emailed me to apologize. My Fiancé has to call her 75 your old mother to help her pull in the huge heavy mattress and box spring in the house. My fiancé is 5’1” and weighs 125lbs. This is completely unacceptable. I will not be ordering anymore deliveries from Costco as they have ruined my confidence in their delivery drivers.

Queen Beauty Rest medium mattress

This is a very comfortable mattress. Not too soft and not too firm. This mattress replaced a sleep number bed. We are very happy with it.

Perfect Firmness

Exactly the feel my husband and I wanted. It is firm and sturdy. Not like people are saying "hard as cement". We wanted medium firm and that is what we got.

Very Pleased

Very solid, comfortable mattress. Isolates movement well. It is firm with just the right amount of memory foam on top. Very pleased.


looks good up today hope it will not sag in the near future

King Mattress Set

Exceptional quality and high level of customer experience

Problems with delivery service + wrong box.

Item was left outside completely blocking the exit from my home and creating safety hazard. Noone attemped to call or knock even though I was home waiting for the delivery all day. This is second occurance with Costco delivery of the same nature in 2 weeks. Last time they left bath tub standing sideways on the porch and blocking my exit from the house. In addition, wrong box delivered, not as shown, too high. Impossible to reach customer service due to impossibly long wait times. No e-mail or chat support avaialable.

Sleeping beauty

All i can say is that i love it!

Sleep well

I’m happy with this mattress. Some said it was more firm, however, I find it is not too firm. Delivery was excellent, but beware they only deliver to your garage or door.


Comfortable. Medium is the right firmness for me.


Mattress is great -very disappointed in delivery company they would not help bring the mattress in the house

Not For Us

Tried to like this mattress, even after first night had neck pain, (both my wife and I). It's not too hard or too soft. We gave this mattress one month to acclimate, even buying and trying different pillows. Mattress is just not comfortable.

Costco's Sealy Premium Posturpedic was a disappointment

It was a good mattress to start, but after 4 or 5 years, it started to sag...significantly. For the price paid, we expected much better durability.

Frequently Asked Questions About Costco

What is the best mattress at Costco?

When it comes to value, the Cocoon by Sealy delivers the highest rating for the money. If budget isn't a concern, Tempur-Pedic offers highly rated memory foam mattresses. However, both of these options may pay to buy direct from the brand for added discounts and perks.

Are Costco mattresses any good?

Is the Costco Casper mattress good?

The Costco Casper mattress is based on their original mattress design, which is no longer sold directly by Casper. Its benefit is its affordable price for the brand name. While many find it suitable, there are some complaints of off gassing, firmness, and durability in some cases.

Will Costco take away my old mattress?

If customers buy online, Costco provides an optional haul away service in some locations. There may be an additional fee for some regions.

Is a Costco mattress worth it?

In some cases, yes. Costco offers a wide array of mattress choices, which is great for those that don't know what they want and are on a tight budget, and would otherwise go into a mattress store. However, it may pay to buy direct from online brands, even those sold at Costco, for additional perks and discounts.
