Endy is a Canadian company that crafts one all-foam mattress in a box based on years of extensive research. Their mattresses are made with a proprietary blend of foams for a medium firmness feel that most customers love. They are also socially conscious, donating mattresses and sleep prodcuts to a variety of charity partners across Canada for those that need them most.
Sleep Science builds a line of latex and memory foam mattresses. Their claim to fame is their 'wedge' technology that provides edge support to every piece of the mattress. Additionally, they are Certipur certified, which means they have low VOC and no formaldehyde in their mattresses. They also use bamboo material in some of their mattresses. Their mattresses are made popular through their relationship with Costco warehouse stores where they are sold at a competitive price vs many of the retail sold mattresses of similar material quality.
Based on our aggregated reviews and our scoring method, we recommend Endy in this match up!

Reading online reviews and getting a sense of how people feel is a great way to figure out if a company is going to be a good fit for you. These mattresses are rated very well by customers overall, but there are some that didn't feel as comfortable. Research more below to see if one of these mattresses will work with your body type.
These mattresses are above average when it comes to support. Though there are some that don't absolutely love the firmness levels of these mattresses, most would describe these mattresses as having the right amount of support for them.
Edge support is really important for those that struggle with mobility or sleep near the side of the mattress at night. These mattresses do well on their edge support and they should support most customers comfortably.
Bowling Ball & Density Tests
Many mattress reviewers and bloggers use bowling balls to measure firmness and support. These mattresses do a good job with delivering even support throughout the mattress, which means they should work with your body to align the spine properly.
Good durability when it comes to comfort is one of the best factors in selecting a new mattress. Though there are some reasons, like a changing body, that would mean we should update our mattress sooner than 15 years, we would all be happier if we knew our mattress would really last. These mattresses, specifically, are competitive when it comes to durability. Based on the specs and a majority of the customer feedback, these mattresses should last over 7 years for most, but some have complained about changing feel. If you are a bigger than average person, review the mattress specs before buying.
With data from customers, you can more accurately choose the right mattress. However, there are a lot of other brands out there competing for your attention. For these mattresses specifically, customers have mixed emotions. Some are ecstatic about their new mattress, but others are less pleased.
Most customers report feeling supported on these mattresses, but others described some discomfort with their mattress choice. For those that are plus size, take a look at the firmness levels and overall specs as you'll want to ensure that your body and spine are supported well.
For those that want a mattress they can sit comfortably on, most will be comfortable and supported with these mattresses. That said, some have had complaints so make sure to review more.
Based on the materials that are in the mattress, the average durable mattress will stay comfortable for at least 7 - 12 years. Foam mattresses are generall not as durable long term, while mattresses with springs tend to last a bit longer, but only if they are well made. However, mattresses of any kind that don't offer good durability will start sagging quicker especially for larger sleepers. Sleepers have mixed things to say about these mattresses. Some describe good comfort, but others have had issues with lasting support.
My husband and I absolutely love our new Endy mattress. I don’t think we have ever slept so well. Delivery was quick and set up was easy. We would recommend this bed highly to anyone looking for a medium-firm mattress.....Support Canadian business!!View More Reviews
Best bed ever! Perfectly fills the contours of my body, allowing my muscles to relax and wake up rejuvenated. The best therapeutic bed I have tried out.
My hubby and I weren’t sure what to expect when buying an endy. The customer service has been great and the mattress is very comfortable. We are sleeping like babies! ❤️
We love our new mattress! No more tossing and turning all night. I have issues with my shoulder and this has helped me sleep on that side. My husband has restless leg syndrome and this has lessened it and when it does happen, it's not waking me up anymore as I can't feel him moving around.
I love my new mattress! And the order/delivery was stress free. Thank you Endy!
Exactly as advertised! Love it. No more sore hips. Thank you 😊
love my Endy!
The only thing getting us out of our bed in the morning is the kids. We love our Endy.
I love my new Endy mattress, I have not slept this well in a long time.
BEST BED EVER!!!!!!
I bought this for my 3 year old daughter. She slepts so well on it and called it her ‘cloud’ bed. It has been wonderful cuddling on this mattress.. hard to get out. The most amazing part was that I ordered this mattress on a Thursday night and found it on my doorstep Sat afternoon!
Awesome!!! Highly recommend this mattress. Don’t hesitate buy this mattress!!!
Perfect for our guest room and so affordable!
Our old mattress was an 11 yrs old, lumpy pillow top. We upgraded to a king Endy when our daughter was 2 weeks old and even with a newborn we have had the best sleep ever! Sure I wake up for her, but otherwise I am so impressed with how comfortable this mattress. I’m dreading one thing about our upcoming vacation and that is having to sleep on a mattress that won’t compare. Super fast shipping for an amazing product. Win, win, win!
Great sleep & stay warm after you get up and come back to bed
Sleeping on angels.
My husband loves it, and I am getting it to it
I took a chance buying it and waiting for my body to adapt. It is a little too firm for my liking so I give 3 stars instead of 4. Not my type. It is good only to sleep on my back so I'm kind of using it to force me to do it. I'll probably return it.
The mattress is way to soft for me.
Love love love our Endy. Both of of us have back issues and trouble sleeping, But all issues are improved....feels like we we hit the jackpot! We highly recommend!
I am in love with this mattress! Takes a few nights to get used to it as they say, but after that it is the most comfortable mattress I have ever slept on! And the mattress was delivered in 2-3 days after ordering! Amazing company!
I was hesitant to replace my bed, but after sleeping on an Endy Mattress I can’t believe I didn’t do it years ago.
Can not believe that I could fall in love again, but I did. Her name is Endy. 😉 Seriously though; this is the best money we ever spent. Highly recommend one to anyone who is having sleepless nights.
We are loving our new Endy bed
Finally I can get through the night without my shoulders killing me
This is the best mattress I've ever purchased, it takes a good week to get used to. I'm having some of the best sleeps I've ever had.
It’s been 3 weeks now and we’re really happy with our Endy mattress and pillows! Everything about the service has been great!
super comfortable, just the right about of squishiness
With my old mattress I get up in the morning having back pains. A week after using Endy I dont feel it anymore! I love our Endy!
Bed is so comfy!
Great mattress, great customer service. Would definitely recommend!
This was an the Best company to deal with. Easiest mattress ever to install, and rave reviews from our guests! I tell everyone looking for a new mattress how amazing the whole process was, how comfortable it is. Love Love it!! The only negative may be that it's a little "too" comfortable for the "guest" room...lol
I just thought aging brought sleepless nights but since I received your mattress less than two weeks ago, I have been sleeping eight hours a night after decades of thinking that I could only sleep about five. I wake up feeling that all my vertebras are in place too. I am so grateful.
So far I love it. Never slept better. Back pain gone.
Both my wife and I were skeptical and were worried that one of us would like it and the other wouldn’t. After 4 weeks we both agree it’s the best mattress we’ve ever had. It’s ruined hotel mattresses, nothing is as comfortable as our Endy.
It's been a month now, sleeping better than ever. Thanx Endy.
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.View More Reviews
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.
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!!!
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!!
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!!!
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!
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!
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!
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!!
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!
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.
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.
Best mattress I've ever had
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.
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.
Mattress is so firm and comfortable!
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.
It’s a very good mattress and my mom loves sleeping on it. The mattress is true to the firmness.
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.
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 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.
the bed is comfortable but its been only 1 week since I have been using it.
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.
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 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! Sleeping great & elevate when needed without disturbing spouse.
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.
Sleeping was too warm and too firm
So far so good. Hoping for a number of years of the same. Attractive and comfortable.
Very good quality; perfect firmness and it’s a good looking matress.
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.
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.
Super comfortable. Easy to assemble with two people. We love the adjustable settings. Zero gravity is divine!
This is the most firming bed i ever experienced. May be too firm.
Excellent bed great support
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.
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.
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.
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.
Sleep in this mattresses for one month. Good quality but just too firm for me.
