Casper

Casper is one of the most interesting trend-setters in the mattress-in-a-box space. They, by and large, shed light on how a brand with great marketing and a popular product can disrupt an industry. Casper has kept innovating its products with their 4D Sleep Technology, and four flagship mattresses: The Original, The Original Hybrid, The Wave Hybrid, and The Nova Hybrid. For warmer sleepers, they also offer Snow Technology enhancements in their Wave Hybrid and all new Snow Mattress. But, with all the options, can Casper still deliver on comfort?

Sleep Science

Sleep Science manufactures a line of latex and memory foam mattresses. Some of their mattresses feature materials such as bamboo charcoal, gel, and copper infused memory foams. Additionally, they are Certipur certified for low VOC and no formaldehyde in their mattresses. Sleep Science is well known for their 'wedge' technology which helps promote edge support, and for being sold at Costco warehouse stores where they are available for a competitive price.

Sanity Saved!
My husband and I both have serious bone and muscular issues. Mine from years of being in the Army and my husband from being run over by a truck two years ago. So, we have been on a quest for better sleep for quite some time. No matter how much money we spent on mattresses; we still woke up stiff and distorted in pain. I kept hearing Glen Beck talking about the Casper mattresses so, I finally ordered one even though we had doubts it could be that much difference. We were just accepting the fact that pain was our present and future. The price was much less than expected and the ordering process was simple and effortless. The mattress and foundation arrived in only a few days, much faster than anticipated. Putting the foundation together took no time at all; then we opened the mattress box and watched in curiosity as it expanded to fit the frame. That night, as we got in bed, we were unsure because it felt so different. Seven hours later (longer by far than either of us had slept in years), I woke up first and as I prepared to ready myself for the struggle of moving stiff, painful joints, I realized, for the first time in more than ten years, there was ZERO pain!! My husband had the same experience! So, thank you, Casper, for being the reason we have a new lease on life...pain free mornings and deep, restful sleep through the night. We are in awe and we bow to your genius. Brava!!!

Best sleep ever!
By far the best mattress I have ever owned. I will stick with Casper for all of my future mattress needs!

Amazing Comfort and Support
Unboxing and building the foundation was very easy. The mattress unrolled itself. We did let the mattress air a couple of days for the manufacturing smell to dissipate. Compared to our previous “pillow top” mattress the Casper provides much better all over support on pressure points (hips/shoulders/sacrum). The feeling is indescribable. You don’t sink into it - you’re supported in it. I would definitely recommend Casper to a friend without reservation. In fact, I’d insist they try mine out first (which is what happened to me and I was amazed). The best advertising is a happy customer.

Incredible!!
It fascinated me that it was vacuum sealed. Guys, this is one of the best purchases I have ever made. I also purchased your pillow, which I adore! I was stunned to receive it the day after I ordered it and was incredibly grateful. The bed is everything I hoped for and I thank you for the service I received. You bet I would recommend Casper! Thanks again.

Casper forever!
This is my Casper and I couldn't be happier! I got us the Casper because I heard good things about it, the whole thing was a great experience: the easiest unpacking, assembling and installing on my bed frame ever! I sleep with my service dog and there is plenty of room, no sagging mattress, not too hot, I give this all a big, fat thumbs up!

Awesome. Just what I needed
I work 3rd shift and sleeping during the day/afternoon was very difficult. To get to, and stay, asleep. I would have to take sleeping aids and the such. Now, I can just put my head down and I am out like a light. At anytime I want. With no sleep aids. Just head down and out wake up fully rested and ready for another night. Thanx

Love it!
I knew the 'set up' process was going to be easy, but it still surprised me. I got the box into my car and my place all by myself (it's large but manageable), and then it was less than 5 minutes to unbox it and have it ready to go. An absolute breeze. On top of all that, it's a dream to sleep on (you see what I did there?). The mattress is firm enough to be supportive, but also cushions your body and molds to it so nicely. I work out of town for two weeks at a time and when I return home I am just dying to crawl into bed. Worth every penny :)

Worth every penny
Easy unpacking, and great to sleep on! I was able to unpack by myself.

Casper
Love this bed, sleep is amazing...

Sleeping on a cloud
I ended up buying everything available: foundation, mattress, pillows, sheets and duvet. When all the boxes arrived I was like a kid in a candy store. I was so ready for a new bed and getting a better night of sleep. Setting up the foundation was super easy, but what I was really ready to see with my own eyes was the mattress coming to life. Once I had everything unboxed and made my bed I couldn’t wait to go to sleep that night. That first night was like sleeping on a cloud. Now after sleeping on the Casper bed for over 2 weeks I have had a better nice sleep, I’m not waking up in the middle of the night trying to find a comfortable spot or waking up in the morning to a sore back. I’m truly impressed and very happy. I will be definitely recommending my family and friends about Casper.

After all these years...
Great mattress. So glad to get away from spring-type mattresses that maybe are ok for about a year, and then start to sag. I have spent thousands of dollars on these mattresses, have had them replaced on warranty at least three times over the years. Never go back.

Nothing, nothing helps you sleep better than this mattress.
From the start I was a little skeptical, but a very good friend recommended Casper. So my wife and I talked and decided to give it a chance. After all, with 100 days to try it out there was only a little effort to lose. So we unpacked the mattress and let it sit open for 24 hours. I have to say, opening the box and cutting the wrapping off was a cool experience. We replaced our mattress with the Casper, kept our original box spring. Night one it was comfortable, firm, cool to the touch, and felt like a hug. Night two I realized that the edge was not as firm as a standard mattress, but then again it was not hard on the edge. I realized that I have been sleeping on the edge of my mattress and it was not doing me any favors. The Casper changed my body alignment in the bed and I am glad it did. After a week we both agreed it was a good mattress. After a month we decided to keep it and discarded our original mattress. It has been over a year now and I would not trade the Casper for anything. If you paid me a million dollars, I would give you the mattress, but I would buy another one and keep the rest of the money. I played college football, weigh over 300 pounds, have bad knees, hips, shoulders, and back, but this mattress allows me to get out of bed without any pain. With my old mattress it would sometimes take me 20 minutes to walk after getting up. With the Casper I hop out of bed with no pain, it is the best part of my day. The best part is the Casper still looks brand new, no depressions or sagging at all. Even the four dogs that fight for position during the day have no effect on the shape if this bed. Now lets discuss the cooling effect. I used to sweat every night in my old bed. The Casper breathes, period. I do not sweat at night any more. It is cool in the summer and adjust perfectly to your temp in winter. I can wear long PJ's and still be comfortable. And then there is the motion of the mattress. Ask my wife and she would tell you that I never get up in the middle of the night anymore. It is not true, but she just does not feel it. I don't feel her get up in the mornings either. I never needed an alarm clock until the Casper, she got up first and her moving would wake me up. Now she gets up and my alarm goes off to wake me up and I think that some days she over slept. Nope, she just got up without me feeling it. If you took the time to read this review, then do yourself a favor and try this mattress. If you don't like it then you are in the vast minority and I have a slightly used mattress to sell you. Give it a try and at the very least you can cut open the wrapping and watch the mattress grow in awe!

Overall Impression of this Mattress
In a word, I LOVE this mattress. It's the best I've ever owned. It took me a full month to adapt to it, though, just as the Casper documentation warns. I even considered returning it, but I can now say I have not had better sleep in decades.

Best Sleep in Years
Bed and foundation arrived fast! Set up was simple and easy. I ordered the foundation as well it sleek and attractive looking super simple to set up. I had been having back problems which my old spring mattress just made worse. It took a few nights to adjust but now I/we sleep better than ever. I wish I would have ordered months ago instead of waiting so long. So happy you offer payments with affirm. End of story we and our dog simply love our CASPER!

Our New Mattress and We are Thrilled!
I was skeptical about buying a mattress that comes in a box but when I watched the video on how Casper Co. developed the mattress, I thought what was the worst that could happen, we ship it back within 100 days. I had had a small back pain from sleeping with my 5 year old and sleeping crooked. The Casper mattress was delivered. My husband and I had been playing musical beds with our twin 5 year olds. The moment the bed came into the house, we were like, mommy and daddy are going to sleep in our room in our new bed. In 1 night, my back pain was gone and I slept in the same bed as my husband after weeks of moving from bed to bed in our house. My husband loves the bed and refuses to sleep elsewhere now and I just sneak out of the kids rooms back into the Casper. I think we may buy one for my father for Xmas! Loving the bed! Saved my back and rekindled my marriage, lol, in a manner of speaking. Thanks Casper!

Results
I was able to unbox the bed by myself. Some struggle involved, but very doable. I thought the mattress would be squishy like my previous foam mattress. I was surprised at the relative firmness. The results don’t lie, I have been significantly better. Very happy with my Casper.

fantastic
unboxing was fine. easy and quick. it’s honestly the best mattress i’ve ever slept on.

Great mattress
Setting up the Casper sleep system was fun, simple and fast. We had it unboxed and set up in about 45 Minutes. I was a little worried about having to get used to this type mattress as we have had a waterbed for the past 30 years. Boy was I wrong. From night one, my wife, my dog and I have slept great. My dog even sleeps in in the morning. She doesn't want to get up. This is the most comfortable mattress I have slept on. Great job Casper. Highly recommend it. In fact, one of my sons is considering buying one.

Cover seems great. Easy to get on the bed.
Yes, easy process to put the frame, foundation and mattress on. I had the best sleep since before I was pregnant and my baby is 7 months now! I'm a side sleeper and I found it super comfy. I actually like that it's lower to the ground than a double sided pillow top, as my dogs can get up and down much more easier now.

It's like sleeping on a cloud
I had various spring mattresses for years. After a while, all of those springs can be felt and they press against every part of the body in the most painful way. I would wake up with pain in my neck, hips and the arm on the side I slept the most on during the night. And after doing a month long sleep tracking app, I found that I was only really averaging, at most, 2 hours of deep, restful sleep a night. After only one night I spent four out of the six hours asleep in a deep slumber and had no sleep-related pain. The only downside is that the cooling technology has me adding an extra blanket but that just makes the bed cozier.

Very comfortable bed, supportive enough for my neck and back issues.
Love my Casper! I've been sleeping on it for about 2 weeks now, and it's lived up to the hype. It offers enough support for my back and neck, and I can sleep comfortably on my back and side. Was easy to set up and started sleeping in it that very same day.

Sweet...!
We have let it "air out" for 5 days, to get ride of the chemical smell, before using. It's still there after a week...

Love the mattress!
The delivery was 2 days late. Oh well. The product is fantastic.

Love it.
Sleeping great! Waking up with out any back or neck pain. Energy levels during the day have gone up. Happy with my Casper purchase

Great Mattress
I had the same spring mattress with a memory foam pad on top for many years and thought it was comfy but my back always hurt. After the first night on my Casper mattress I knew it would be great for my back. I am extremely happy with it and feel very comfortable. I also upgraded from a Full to a Queen and it is the best! Highly recommend it to anyone who likes a comfy and supportive mattress (AKA everyone.).

YAAAAASSS!
This bed is the JAM! I haven’t slept this well in ages. I usually toss and turn all night long, but with the new Casper, and only a few days in, I’ve already noticed that I am actually getting a full night’s sleep as well as waking up not feeling exhausted and achy. This bed is basically like sleeping on a perfect cloud. We also purchased the pillows and that was the icing on the cake to make it that much better. My body is already thanking me!

YAAAAASSS!
Sleeping through the night is actually a thing? Who knew!

Defines how sleep should be experienced!
I works nights as a paramedic and I was starting to experience horrible back pain. This mattress just sucks you in. I also feel like this is perfect for someone who sleeps during the day. It muffled vibration so when my little one walks in and bangs on the side of the mattress I don’t feel it. Thank you Casper!

Comfortable bed, great buying experience
Get a bed over the internet? Get a bed in a box? Get a bed without comparing it next to dozens of other possibilities? These are all out of the box concepts (get it?) but it worked for me and my wife. The bed was delivered to my door less than 48 hours after I ordered it. The box was incredibly heavy and it required some muscle to take it to my bedroom. It also required work to unwrap it. But compared to going to a local store and picking it up, it was 100 times easier. The bed itself is very high quality and comfortable. We have the original high end memory foam bed in our hour. This bed is as good if not better than that bed - for fraction of the price. We are getting great night of sleep as a result. I would never buy a bed any other way and from another brand.

Best sleep of my life!
The unboxing experience was super easy literally no tools needed just putting everything together, I had got the foundation, metal bed frame, mattress, and bed sheets and everything feels amazing, perfect height all together and it all felt greatly made. The sheets feel just like hotel sheets, I love them. Next I’ll be getting the pillows!

My Daughter LOVES her new Casper!
Here's a little secret. I used to work for a large mattress company, I know mattresses. When my Daughter complained of the lousy spring bed she had, I knew what I wanted to do. Truly, the best way to buy a bed is to simply have one sent to your home, with a free-trial, it is a no-brainer. I was not home when the bed arrived, my Daughter and Son set it up, easy, they said. But the next morning, when my Daughter awoke, she was all smiles. "I had the best night of sleep, ever! Thanks, Dad!" That's all I needed to hear. Thank you Casper.

Excellent! I am so glad I opted for the Casper!
Tremendous difference from my former traditional mattress. I would definitely recommend to anyone who is interested in making the change!

Durgen
Fast delivery and great product. I woke up feeling very well rested.

Wonderful mattress
Easy unboxing. Love sleeping on it. I would and have recommended this to friends.

Impressed the first night
Unboxing the mattress was easy. The experience of sleeping on the mattress far surpassed my expectations. Despite the break-in period, teh morning after the first night sleeping on the mattress, I knew I have been lacking restful sleep up until now. My previous mattress was a spring with a foam topping. every morning I would wake up with some hip pain but never thought it was my mattress, but rather the shoes I was wearing throughout the day. After my first night on the Casper mattress, no pain. Beyond grateful for the most restful sleep I have had in a long time.

Great Sleep @ a great price
Love the mattress! It was either the casper or a matress for 3,000 and im glad I saved my money and went with casper. I have one of those name brand memory foam mattresses in my spare room and you cant tell the difference between that and the casper mattress. I am very happy with my purchase!

I loveeeee it
It was super easy to unpack !

Great mattress & GREAT PILLOWS!
The unboxing experience was good. The only problem I had is....I ordered the mattress on Wednesday the day before Thanksgiving. We were in Palm Beach, BUT we live in Chicago. I told the manager that we would not be home until Monday. She said it doesn't go out for 2 days, which would have been Monday. On Thursday (Thanksgiving) I received an email from UPS that the bed was going to be delivered on Friday, the day AFTER Thanksgiving. IT WAS A BIG FIASCO trying to reschedule the shipment. I spent half a day, contacting the store, UPS AND then the following week, I couldn't get the bed delivered. The girl at the store got that done for me. IF THE STORE WOULD HAVE LISTEN TO ME, WHEN I TOLD HER THAT I WOULD NOT BE HOME, THIS WOULD NOT HAVE HAPPENED. IT TOOK A LOT OF TIME ON MY PART, AND I AM NOT HAPPY ABOUT IT!

great
yes, highly recommended

NEEDS GOOD FOUNDATION - dont use bunky board!
We bought this mattress over a year ago...had no idea that they sold a separate foundation. Spent months replacing the bunky board we got from Crate and Barrell 2 times and dealing with back pain, even called the mattress mfr. The mattress mfr said they recommend their foundation instead of bunky board. Ordering it today, hopefully it will take care of the problem but paying $50 more than if I bought them together from the start. They need to update the description and recommend the foundation if they don't buy it separately OR don't even sell the mattress alone. Description said it needs a 'solid' foundation...what does that even mean? I had a hard time trying to find a bunky board that is solid wood from many retailers. Crate and Barrel's new bunky board is made of compressed cardboard! A painful process, but I like the mattress.

Works well for us
The mattress is definitely on the firm side but we both find it about right. After 11 months, the bed seems to be wearing very well... no signs of change in feel or shape. The adjustable bed is used in zero gravity every night for one of us and not used at all for the other. The adjustable bed works well for back sleepers but not side or stomach sleepers.

Six years later, we still love it!
This bed is the best we have ever slept on, even 6 years later. We have the queen, and now want a Cali king (we now have a dog sleeping with us), and will be buying another one of these latex matresses from Costco. This one will go into the guest room, and it looks brand new. It has not settled or sagged at all, even though it is used every night, by 2 people. It is NOT hot, either. The memory foam mattress we bought from Costco first, was hot, however. So we returned the memory foam and got this latex mattress. We are so happy!!!

Not so great!!
I did what i thought was plenty of research before i bought this bed.. I've waited a full year to try and get used to it, and kept telling myself and my spouse it would get better. Not only was it hard and uncomfortable but, from 3 months on, it had big depression on both sides. It seemed to get worse , not better! The only good thing is i bought it from Costco, so they agreed to take it back, no problem! Yea Costco!!

very good customer services
I bought this bed on July 7, 2016. It was my first Costco online shopping. As in warehouse shopping, the online service was very good. The delivery company did not call me to confirm the delivery time but Joshua and Carlos did great in the delivery of the bed and setting it up. Brandon at the distribution center was excellent. I could test the bed before the purchase. The latex mattress feels cool in summer compared to other types of mattresses. I hope I enjoy my bed for many years to come. I love shopping at Costco!!!

Super Comfortable; great support
I've purchased 3 of these mattress so far. The first one about 3 years ago, then another one the following year and another one a couple months ago. the first one was in a guest room and the other two were for two of my kids who loved the bed when they slept on it while visiting!

Helps with my back
I bought this bed over 2 years ago, maybe 3 years now. My husband was a reluctant buyer, because we are only early 40's :) He thought adjustable was for the nursing home. But he had enjoyed it just as much. It hasn't helped his snoring, but he enjoys the leg elevation and massage features after a tough day or workout, and elevation of his head when congested. I have had a couple of back injuries from car accidents, and sleep considerably better on this bed than ANY OTHER!! We had a memory foam before this. This is NOT memory foam. Memory foam sinks in with your weight, then when you turn over you fall back into the rut you created. Ours was also hot. This foam doesn't radiate heart back at you. I love that! It doesn't sink in. It has great support. It is nice to be able to sleep elevated without getting up in the middle of the night to prop up or go to the recliner. My bed sleeps just like it did almost 3 years ago. No sagging, indentions, or soft spots. It does creak a little when adjusting, nothing a little wd-40 can't fix. The base and massage features still work like a top. No problem! Good buy!

L-O-V-E IT!!!!!!!
Purchased and received this split King organic mattresses with adjustable bases on April 8th, 2016. What a great product! Both my husband and I absolutely love our mattresses! The adjustable bases fit perfectly inside our existing bed frame, and the mattresses are sooooo very comfortable. I have always been a side sleeper, but no more! I'm able to easily sleep on my back now. Since I am a professional singer, this is a real plus for me. Also, the adjustability allows me to (among other things) raise my head ever so slightly to allow for sinus drainage as well as legs for additional perfectly tweaked comfort. The mattress cover is soft and also feels luxurious. A 3 inch layer of softer 19 ILD natural latex perfectly compliments the firmer 32 ILD layer underneath it to softly cradle with no pressure points yet support my body superbly. Adjustable base works great. Fully articulates for customization. Zero Gravity pre programmed position is heavenly! Don't wait. Buy this now!!! You'll be glad you did! Great price and great product. Thanks Sleep Science - Well done!

Wonderful Bed!
We got this bed a couple of months ago. It is very comfortable. Unaware another person is in the same bed. Mattress is fine for us, not too firm and not too soft. No odor.

Delivery company had great personnel.

One side had a control box (located under the bed) that failed in the first few hours. Costco called the company and we had a new one installed by the company in a few days.

I would suggest going to check out Dreamfit mattress covers (they come in twin xl and their kings sheets (2 twin xl bottom sheets with one King top sheet. Their bottom sheets and mattress covers have extra elastic straps to hold the sheets in place. I found these after much research. They stay in place great. Love my bed!!

Comfortable..natural latex adjustable
The mattress delivery was great..even on time. The mattress itself is nice ...no sinking in like foam. Soft and supportive. The adjustable base is great. I do wish the lights on the remotes would come on before you try to poke the right button. Zero gravity setting is awesome!

Very comfortable
Its very comfortable. Firm for support but not too firm. My wife & I think it is the best mattress we have slept in. No smell at all.

It's SOFT, not 'medium with a bounce'
Disagree with the SUBJECTIVE product details 'Sleep Science comfort scale: medium with a bounce.'

There is missing objective ILD firmness scale info in the product details. For me, 5'3 and less than 120 lb, this is surely a soft latex mattress. In general, The 'soft' designation corresponds to an ILD rating of 19-21. The ILD rating for the medium range is 24-26. After digging yourself, then you find this mattress has ILD 19 on the top 3 inch layer over another 6 inch of 32 ILD.

Mattress
Best mattress I've ever had

Comfortable and pressure relieving.
The delivery was early by several days and happened without notice, but luckily we were home to receive the mattress. Unpacking and getting it ready for use was seamless and fast; we didn't have to wait for several hours and slept on the mattress within hours of set-up. So far, the mattress has been comfortable, relieving pressure in all the right places while providing support. I wake without the aches and pains I had come to assume were "normal" as I grow older. I am optimistic that it will continue to be as comfortable for many years to come.

Very Very Very Firm
We found this mattress to be extremely firm. We bought a softer topper to help but unfortunately it did not. We have purchased 5 other foam mattresses for ourselves and family members and had been very pleased. This one was just too firm.

Awesome mattress
Mattress is so firm and comfortable!

I love my bed!
We picked this up because I have a bulging disc in my back and even though our other mattress was only 3 years old, it wasn't cutting it. I Love This Bed!!! We've only had a couple of months but so far so good. It's firm the way I need it and supportive. I'm a big guy 6'2 270lbs and it's great for me.

Perfect mattress !!!
It’s a very good mattress and my mom loves sleeping on it. The mattress is true to the firmness.

Great firm mattress!
Love it feels great for my back and gives plenty of support. Even better you don’t feel any movement when there’s someone next to you.

P
My husband and I both love this bed! It keeps us from getting overheated (a big issue of mine) and is the perfect firmness. This is our favorite bed after having two other gel cooling foam mattresses that have also been purchased recently. Actually, this is our favorite bed we've ever had and we are both 60.

Very happy with purchase
Very happy with this purchase. Mattress is super comfortable and the firmness just right for both wife and I. (Of course firmness and comfort are subjective and very individual.) The adjustable functions work great and motors are pretty quiet. This was a major factor in our decision as my wife just now had shoulder surgery and sleeping in a reclined position is needed. Packaging and assembly are quality although it would be recommended for 2 people to carry base pieces and mattresses from delivery location to bedroom. Assembly video very helpful. Time will be the teller for durability, but very happy with the purchase and first impression.

good
the bed is comfortable but its been only 1 week since I have been using it.

Favorite place
Love my new Sleep Science split king bed and adjustable frame. I have only slept in in the last 4 nights so this is an early evaluation. We had a temperpudic for the past several years but this has surpassed that at more than half the cost. So far this bed is my favorite plays to be.

WORST MATTRESS EVER
Don't waste your time and money . I had this mattress for more then a month. An every morning i woke up with sore Back .I am been using memory foam mattress for more then 10 years and I never had such a horrible mattress for the price i paid . I am glade i got it from Costco so I could easily return it ..

Good mattress
Good mattress that was delivered one month late. Came rolled up. Have to let it rest for 3-4 days to self inflate and acquire firmness. Since its brand new cannot say how long it will remain firm

Great bed & purchase.
Great bed! Sleeping great & elevate when needed without disturbing spouse.

Worst purchase
Terrible mattress. Got it delivered after a month after it’s shipped (which is after a week after I ordered). Mattress has some stains on the bottom. Couldn’t spend another month and half without a mattress so opened it. Both Costco and sleep science have deceived me to the core and lost all the respect and trust I had in both these brands. It’s not firm at all, people who love plush would rate this below plush rating. I’ve no energy and time now to deal with the customer service at Costco which discontinued email and chat supports. Staying on phone with them for hours and getting mediocre resolution isn’t worth.

Mattress comfort
Sleeping was too warm and too firm

Mattress
So far so good. Hoping for a number of years of the same. Attractive and comfortable.

Very good quality mattress!
Very good quality; perfect firmness and it’s a good looking matress.

Advertised firmness not as anticipated.
Mattress was advertised as extra firm and we have found after 2 weeks of sleeping on it the areas where we sleep are already getting soft. Not sure if we will be able to keep it.

Seriously could be saving my marriage with this
My new wife has complained about how much I enjoy sleeping (i.e. I occasionally snore) which apparently keeps her awake. I had a 10 year old sleep number bed that she despised sleeping on because she prefers a firm mattress (firm as in she'd be more comfortable sleeping on the floor than a soft bed) and I was more flexible. She'd mostly started sleeping in the spare bedroom every night because of these two factors when I saw this bed go on sale around memorial day. I figured why not give it a shot and if it didn't work out, we could always return it. Well right from the very first night she noticed a difference where I slept in the zzzz setting and didn't make a sound. That kept up for weeks until we took a small trip and stayed in a hotel room and the snoring returned. We both totally looked forward to coming back to our bed. I've been sleeping comfortably and so had she. Now we can both sleep together in peace.

Very satisfied with this purchase
Super comfortable. Easy to assemble with two people. We love the adjustable settings. Zero gravity is divine!

Extremely firm
This is the most firming bed i ever experienced. May be too firm.

Sleep Science 14” copper infused cal king
Excellent bed great support

Mattress
It IS a from mattress of very good quality. The massage and adjustability of this bed are great. I’m hoping it softens some, I’ve had it for one month.

Haven't slept so well in years.
After 1 month we are very happy with the purchase. Firm but very comfortable mattress is exactly as described. Motorized stands work very well and seem to be high quality. The price was less than half of what we saw in bedding stores. We should have purchased sooner. My only comment would be that a set up and mattress removal service should be offered.

worst buy
started great...slowly sank and now i feel like i am sleeping in a pothole. it went from good to worst really quick. not happy with this purchase but happy with costco policy. they are awesome.

How good the bed is.
I had the bed for 1 1/2 months, it served whatever expectation I have for this bed that's why we bought it. Me and my husband likes it a lot.

Too firm for me
Sleep in this mattresses for one month. Good quality but just too firm for me.
