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!

I’m looking for a mattress but I can’t test any of them at my Costco. When my wife moved in we used her foam one and I hate it, my shoulders and lower back hurt every night.

My old one which I loved was a firm mattress with a built in foam top. It was firm enough to support me (6’ 250 lbs), but soft enough with the top that I could sleep on my side.

I’ve been on a bit of a mattress journey with Costco. First tried the Sealy Carver Firm—loved it at first, but over time it developed a sag. Now, I’m testing out the Novaform Legacy Premier, and it’s definitely ultra firm.. like too firm, not conforming whatsoever and has zero bounce, which I’m not sure I love.

Thinking about returning it and going for an Avocado instead. Anyone have long-term success with a Costco mattress that held up? Would love to hear what worked (or didn’t) for you!

I have the stearns and foster Lakeridge. After a year it is significantly sagging where we sleep. I’m 5’9 180 and my girlfriend is 5’4 115 for reference, so not people who are prone to making mattresses sag.

Has anyone bought a Costco mattress they are really happy with and had held up well over time?

Currently looking at Novaform Legacy (4.4 stars), Novaform Comfortgrande (4.5 stars), Casper cooling select hybrid (4.4 stars), Casper cooling select memory foam (4.5 stars)

So my husband and I need to get a new mattress and are thinking about Costco for it. We bought a brand new mattress at a random mattress store back in 2017 right after we got married. In less then 7 months it had formed huge divots from my husbands pressure points down the bed. You couldn’t find anywhere to lie comfortably. We tried taking it back to the random mattress retailer after 7 months and they said “nope, so sad. Would you like to buy a NEW one?” So our supposedly first big purchase after getting married turned into a huge waste of $2k bucks.

Since then we have literally bought second hand mattresses when needed at a fraction of the cost. Things were great with that until my dear mother came to visit. You’d think she slept in an Iron Maiden. She then tears the sheets off and saw it had a goodwill tag (the horror). I can’t describe the mix of anger, bewilderment, disgust, et al that came from that woman’s mouth. (I hurried and grabbed the sheets before she saw they were from IKEA just in case that was an issue!)

That brings me to my question for everyone. Anyone acquire a mattress from our store and savior, Costco? I’d like to get some different opinions but let’s be real. The ONLY thing I care about is the return policy. The 2017 divot debacle cannot happen again! Id like to know that if anything happens all I have to do is take it back like that 2009 sofa set, those too small pants and anything from Amylu (sorry guys. Just ew) Thanks for listening! And sorry for any grammatical boo-boos, I’m on mobile

Edit: I really want to thank everyone who commented on their experiences. I have a great idea on what we are going to pick. I’ll update the he post in the future once we decide!!

This Costco favorite is made from layers of foam that are as dense (and probably as durable) as the foam in many online mattresses that cost twice as much.

Looking for people to post positive experiences they’ve had with Costco mattresses. What was your process? What kind of sleeper? What did you settle on?

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

Novaform comfort grande 14" is pretty legit for the price. Had over a year and no complaints.

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

It looks like the $1,800 Tempur-Pedic and $1,400 Avocado are highly rated as top-tier options in this sub—can anyone confirm? I’m thinking about going all-in on the best since I’m returning my Sealy Carver Firm after a few years of sagging and back pain.

Update: Ordered the Novaform Legacy Premier since it seems firmer than the Leesa Legend. From what I’ve gathered, the Avocado is the better choice if I want something less firm compared to the Leesa Legend. Novaform was on sale, while Avocado wasn’t, so I figured I’d try Novaform for now. If it doesn’t work out, I’ll wait for Avocado to go on sale and return/exchange.

Thanks, everyone!
