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.

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.

r/Mattress on Reddit: Best mattress at Costco?
November 15, 2024 -
Been mattress shopping for a few weeks now and its brutal. One person gives a mattress 5 stars, best sleep ever, and the next person says its garbage and the worst mattress they've ever tried.
So rather than risk it with a super-expensive mattress, I'm going to go the Costco route. Looks like there are a lot of options from Leesa to Casper to Simply Modern to whatever else.
Out of all the options at costco, I'm wondering what the best choice is? Let's say $1600 or less...
I'm leaning toward the Leesa Legend Hybrid or Casper. Would loooove some help here! I'm so nervous about making the wrong call!

Last year we bought a Stearns Foster from Costco...we hated it, it was way too stiff for us. Sent it back after 6 weeks and got a different one...I don't remember which one...at first it was great but within 3 months it was way too soft. Sent that one back and got Costco's tempur pedic. That was 9 months ago and we still love it. Best sleep ever. Costco's return service was perfect.... same crew each time. They picked up and dropped off same day...let me take pictures for proof of pick up. It couldn't have been easier. I'm not saying you should get the same mattress we did, I'm saying if you get one you don't like the return process is easy.

I'm a side sleeper and do not wake up with back pain. 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.

r/Mattress on Reddit: Best mattress at Costco for back pain? Tempur-Pedic firm mattress started sagging after 6 months
May 3, 2025 -
I bought a Tempur-Pedic firm mattress (from Costco) around 6 months ago, but it's already started sinking and causing significant lower back pain. I was expecting it to hold up better, especially at this price point.
I’m now looking for a better, firmer mattress option from Costco that provides good support and won’t sag quickly. I prefer something that stays flat and helps with alignment—memory foam, hybrid, or innerspring are all okay if they work.
Anyone with back issues have long-term success with a Costco mattress? Would love suggestions!

There isn't any. Black rest used to be the firmest on their catalog... though it's just medium firm. It dint work out and we returned it. For us, buying adjustable frame with lumbar support turned out to be way better option than finding matters.

Best Costco Mattress - 17 Mattresses Objectively Tested
June 27, 2025 - I wouldn’t recommend this mattress for side sleepers, but some back or stomach sleepers may find it to be a nice option. In our performance tests, the Renew scored an 8.14 overall, which actually puts the mattress in the bottom 20% of all mattresses tested to date. If we look exclusively at specialty mattresses, that rank is slightly better, being in the bottom 25%. Although the score is high enough to be considered one of the “best” from Costco, it’s still not impressive compared to all mattresses we’ve tested.

I’m looking to buy King size mattress at Costco after years and man they’re so many different brands now! Details are in the title. Cooling feature might be good to have! It would be for me & my senior pup (I will add waterproof cover). I don’t have a specific budget because I see so many of them at different price point.
Thank you!

Don't buy a foam bed in a box. They crater way fast. Also, stay away from pillow tops for the same reason.

I’ve been cycling through quite a few mattresses from Costco. I’m 5’8” 160 pounds with back/neck pain and insomnia worsened by Lyme disease. I sleep on my back. My wife is 5’6” 130 pounds and a side sleeper. She can sleep anywhere. I’ve been having quite a bit of trouble with my sleep. For all of the beds, I broke them in over the first few weeks and rotated them regularly. The mt auburn was too firm for me and generally didn’t feel all that great. It was a decent mattress overall but wasn’t it for me. Like most mattresses without a softer pressure relieving layer, it caused hip stiffness and pain. Sealy posturepedic ridge crest was a step up. The euro top added a decent layer of comfort, but the bed started hammocking within a few months and became uncomfortable to me as I really like an even surface. My wife liked this bed though. We briefly tried the 12” sleep science Sonoma flippable mattress but I couldn’t last more than an hour on it. It felt cheap and unsupportive. The novaform serafina is a decent feeling but firm mattress that I occasionally sleep on at my parents house. Well constructed but I find it to not have enough pressure relief (though maybe it’s not well broken in). The Sleep science 13” Napa is my favorite of them all, but it only comes in a split king and I already have an adjustable base. The memory foam comfort layer is thin but relieves pressure, and the latex layer under that does a great job of easing you into the denser foam beneath. I’ve only slept on it once and it felt great, but when I demo it or lay on it, it feels amazing. Kirkland Stearns and Foster. I had this for the longest, about a year. I wanted to keep this mattress forever but there were a few flaws that ended up disrupting my sleep. The quality of construction and materials feels great. While it came firm, it broke in nicely and was a premium feeling mattress. I ended up adding a 1.5” inch cooling memory foam topper to add just a bit of pressure relief and it felt perfect for a while. After about 9 months, the body indents were starting to make my shoulders shrug upward. The kings ridge pressed on my side as well. And the edge support is too wide, as those springs wear differently than the main support coils. All of these things together caused the usable sleep area to be quite small on the king mattress and it stopped being supportive/comfortable to me. If this stayed how it felt I’d have kept it. Tempur pedic flex prima hybrid. This is the bed I’m currently on, it’s been about 2 weeks, so I don’t have a full review of it, but it’s been decent. I like how uniform the surface feels. It’s quite firm right now, but I’m expecting it to break in a little bit. If it’s a 7.5 firm right now, I think the bed will be great at a 6 or 6.5. It provides great support, but just a bit more pressure relief would go a long way. I might try a 2 inch Tempur pedic topper on it to see if it gives it that softness without losing too much underlying support. Overall, I do think many people (my wife being one of them) would have been happy with many or most of the mattresses I’ve tried. Costco’s return policy is keeping me sane while trying to figure out how to deal with my aches and pains. I’m realizing I should probably turn this into a post haha

Hi guys, my parents are looking for a mattress to replace the one they've been sleeping on for the past decade. We initially got one from Mattress Firm but noticed sagging after sleeping on it for a couple of months. It was a headache trying to go through the return process for the mattress. We're looking to Costco to get a mattress since their return policy is really good. Do you guys have any recommendations for "Firm" mattress that Costco sells?

Limiting my search to Costco because I’m in a big city and the pain of heading over to various mattress stores and the woes of delivery are too much. We are 7 years into a nectar mattress and I wake up daily with my lower back soooooo stiff and im hoping it’s just my mattress and not that I’m elderly at age 35. I’m a stomach sleeper and weigh between 120-125 lbs and my partner is ‘ 190 and a back and stomach sleeper. I think? I like firmer mattresses with plushier pillow tops but honestly who knows. Sometimes pure memory foam beds feel too squishy and like I’m sleeping in a giant dog bed. I’m looking at the Novaforms but very open to ideas!
My spine thanks you in advance

My experience with the Novaform comfortgrande advanced gel memory foam mattress has been unpleasant. I’ve had it for about a year now and I regret purchasing it. The best way that I can explain it is that it feels like a hard marshmallow. It’s hard to move around on because I just sink right in. It has given me nothing but collar bone/shoulder discomfort and more recently it has been giving me lower back pain and hip pain. I’m only in my early 30s, but I’ve never had a bad experience like this with a mattress before. I’m finding myself sleeping sitting up propped up against my pillows just to avoid the pain and discomfort.

Mattress Buying Guide | Costco
Back sleepers do best with a mattress that offers consistent end-to-end support to keep their neck, shoulders, and torso perfectly aligned. If you enjoy sleeping on your back, consider purchasing a mattress that has medium to medium-firm support, with light contouring to keep your spine properly positioned.
