I just ordered a king online this afternoon! $525 out the door after the deal and my cash back certificate. It arrives Wednesday, but I'm planning to let it unstink for about a week before using.

r/Costco on Reddit: New Casper Select "Cooling" Mattress Spotted
February 15, 2024 - Excellent mattress. Stays cool and is a medium-firm. No issues at all even during the heatwave. ... It’s just repackaged. I do not recommend ... I'm pretty sure the older Casper Select just had regular memory foam whereas this newer one has gel memory foam which is supposed to be more cool.

r/Costco on Reddit: Casper Cooling Select Memory Foam Mattress - ON SALE - to try or not to try?
March 23, 2025 -

This Casper mattress just went on sale in my store for $759 and I was soooooo tempted to try it. But I could not get the reviews to load while in the store so I passed for now and hope it's still there if I decide to go back and get it. Have you tried it? Can you give me your thoughts? I know mattresses are so subjective but it's such a PITA to return so I'd rather at least know if it's worth trying. I LOVE foam/memory foam mattresses and my current mattress is BIAB so I know it's in the ballpark for me. TYIA!!

r/Costco on Reddit: Casper Cooling Select 12" and Novafoam 14" Comfort Grande Comparison
June 5, 2024 -

I'm referring to the Novaform 14” ComfortGrande Advanced Gel Memory Foam Mattress and Casper Cooling Select 12" Memory Foam Mattress

Sharing since I've seen great deals on Novaform and Casper mattresses at Costco for the last couple of months and someone else may be considering. We've purchased both (memory foam versions, not hybrid).

A couple of months ago, we needed to furnish a guest bedroom on a budget. I was pretty skeptical about inexpensive foam mattresses, but we took a gamble on the Novaform 14" mattress for the guest bedroom and were pleasantly surprised with it (guests complimented it more than once, and we slept on it a few times too and were impressed). It's pretty firm (a little too much for my wife), but I thought it was fantastic. The "off-gassing" was genuinely strong from the Novaform and took a week or two before the bedroom didn't have that smell.

Since that ended up being a happy purchase, we started considering doing it again to replace our aging and sinking memory foam mattress. The Casper mattress retails for 150 bucks more than the Novaform, but was on sale for the same price as the Novaform, so we figured it'd be a better choice (plus, my wife wanted something a little softer than the Novaform).

We went for it and bought the Casper mattress for ourselves. We both thought it was way too soft, and were thinking about returning it after night 1, but we're certainly going to now after 3 nights.

We sink in worse than our 7 year old mattress, we're both sore and tired. I weigh like 180 pounds, and if I sit at the end of the bed, I'm almost sitting on the box spring. We have to lay as far as we can away from each other not to sink/roll towards the middle.

If you've got 400-500 bucks to spend on a mattress and are looking at Casper or Novaform, I'd recommend Novaform. My wife found it a little too firm but was otherwise happy, and we both immediately knew the Casper wasn't gonna stick around. We're gonna be sleeping in the guest bedroom tonight on the Novaform while we wait to return the Casper 😂

r/Mattress on Reddit: Bought Costco Casper cooling select 12" Hybrid Medium Firm and love it
April 4, 2025 -

I finally replaced my 2015 Tuft and Needle Kind size and 20+year old box springs. New box springs were Serta available at Costco. The difference is incredible! I love the new mattress even though it has only been out of the box for 2 hours before we slept on it. Very happy with my purchase. I'm a tall 200lb back and side sleeper, wife is a stomach sleeper. We both feel like it's plush and comfortable yet supportive. No more back and shoulder pain from the old sunk in mattress. No more ridge in the middle of the bed from the old broken down box springs.

r/Mattress on Reddit: The new Casper Costco Cooling Select Hybrid was a nightmare, please help me find my dream bed
April 29, 2025 -

Title says it all. After my third night on the new Casper Cooling Select Hybrid, it's going back to Costco. For anyone else considering this mattress and looking for information:

  • About me: Side sleeper with scoliosis both in my upper and lower back. Low back usually feels fine. I struggle with neck and shoudler pain frequently, though. 120 lb female.

  • Mattress history/what we like: We got a new place where we can fit a king bed. We have two queens: original all foam Casper dinosaur which will be replaced by the new king, and a Westin Heavenly bed (2016 edition, basically an old school Beautyrest innerspring with a soft pillowtop while still being very supportive even right up to the edge). My husband loves the original Casper, I love the Heavenly. The old school Casper is fine for me and causes no pain, I just don't particularly like it, either. We also purchased the Casper Select Original from Costco for the guest room at my parent's two years ago That one I feel the same way about (it is fine, I don't love it.) They changed the Heavenly so it is no longer the same, and also it is too expensive for us at the moment (need to stay under $2k for a king, ideally less). We thought the Casper Hybrid would be a good middle ground.

  • Verdict on the Costco Casper Select Cooling Hybrid: WORST. MATTRESS. EVER. Light years softer than the other two all foam Caspers, by a really long shot. The edge support is non existent and my hips just seem to sink right down into the depths of hell on this mattress. I have slept on it for three nights and for 2/3 of them I have had horrific back pain the next day. It has taken the crown for "most pain inducing mattress I have ever slept on", a title previously held by the mattress at my parent's place that was decades overdue on being put out to pasture and hurt us both so bad we replaced it so we could visit them. If you have an all foam Casper now and are considering this one, be aware that this bed does not feel like it at all. The softness feels nice for a minute or so, but then it becomes a sinkhole in the middle zone. For what it is worth my husband does not mind it, but he is also not that particular. A friend came over the other day and I asked her to lay on it for her take. She (similar size as me) agreed that it is way too soft to be comfortable.

Where do we go from here? If we stick with Costco, what should we consider? The reviews on the Lakedridge are extremely mixed. Given I have back issues I would prefer too firm over too soft (and you can always add a topper). I have also read that it is supposed to be similar to the S&F Estate Medium which I laid on at Mattress FIrm and liked, although many reviews say it is much firmer. We also both liked the medium Beautyrest Black at Mattress FIrm (not sure which model, exactly), but that is out of budget. Based on my history, I am thinking I like firm mattresses with plush pillowtops, but it seems the whole world is going the foam/hybrid direction and those are hard to come by now. Is there one out there that is readily available to try, feels similar to the Westin Heavenly or Beautyrest Black, and comes in closer to $1500 or less? Is the Lakeridge even worth a try? TIA!

Casper Cooling Select 12” Memory Foam Mattress : r/Costco
May 11, 2024 - Omg I’m also a side and stomach sleeper currently mattress shopping and what I’ve learned is that those two sleep positions require completely different things. Side sleeping needs plush and comfortable and stomach sleeping needs firm so not sure what to optimize or how to resolve this, but I wanna say I totally feel your pain. More replies ... YMMV. I got got this about 4 years ago and it’s the best thing ever every gotten from Costco. It’s foam so it sleeps a bit warmer but nothing awful.

February 5, 2024 -

Costco no longer has the medium-firm CasperSelect Mattresses (Memory Foam and Hybrid) that it used to have. Looks like they've been replaced with the Cooling Select Mattresses permanently.

From specifications, the new ones are significantly lighter in weight than the original ones. Makes me think they've used foam that is less dense. Has anyone here purchased the new ones yet ?

How do they compare to the older ones in terms of firmness and overall quality ? Any feedback on the mattresses is appreciated. Thanks in advance!

I was wondering if anyone had any experience with this bed. I'm a side and stomach sleeper so I wanted to know if this bed would fit my sleeping style. I'm hoping this bed will also be durable. From what I understand the bed in store is $600 with a $120 discount leaving it at $480 which I find to be a good deal (discount starting August 4th).

I've had the Costco Casper Select Queen mattress for a little over a year -- and let me tell you, it's great! I generally sleep on my side and stomach, and have yet to have any complaints with it. In fact, my girlfriend ended up loving it so much that she got one for herself. After doing a bit of research, it appears that the Costco Casper Select mattress, is essentially a renamed Casper Original -- a much more expensive mattress. Other things to note: While Casper says that the zip-off top cover is not machine washable, I find the opposite to be the case. I have on more than one occasion washed the mattress top-cover. I used the Bulky Sheets/Tap Cold settings on the washing machine, and then tumble (no heat)/air dried the mattress cover, with almost no change to the feel of the mattress or cover. Edit: as u/partytime71 has pointed out, this most likely voids the warranty, so do at your own risk. Additionally, if you plan to buy this mattress, please use a box spring or at the very least a sturdy platform placed directly under the mattress. Slatted bed frames (without a box spring) will change the feel of the mattress -- make it feel softer and make you sink more into the bed. I know this, because my girlfriend does not have a box spring... While it still feels great, it isn't nearly as firm/sturdy feeling as it is when a box spring is underneath it.

Consumer reports had the novaform queen serafina pearl #2 and eventually I think it's still #3 I've had mine for years and can't recommend it enough! It's amazingly awesome. I'm a similar sleeper. Might be an online queen or bigger option only though. Good luck

October 6, 2021 -

Hello!

I've narrowed it down to these two mattresses partially because I can't read anymore reviews or go down anymore rabbit holes. I'm driving myself and my husband nuts :) plus, I like Costco's return policy.

Anyways,

I am mainly a stomach/sider sleeper, I'm 5'6 and weigh 129lbs. My husband is 5'10 and 165 and he sleeps mainly on his side. I run kinda hot when I sleep. I think there is currently $100 price difference between these mattresses at the moment, any reason to pick on over the other?

Thanks for any help!!!!

Casper Select Mattress Review (2025 Update) - Personally Tested
The Casper Select contains an extra layer of memory foam and costs less than the Casper Original. Also, you must be a Costco member in order to purchase the Casper Select. ... The Casper Select does not sleep extremely hot, but it isn’t the best match for people who usually sleep hot at night. A hybrid mattress with more cooling features should be a better option.

My wife and I have been looking for a king mattress and we’re considering pulling the trigger on a 2k mattress from a local mattress store because we were worried about the quality of a boxed mattress purchased online However, today we saw a king Casper 12” select mattress marked down selling for 300 dollars and we made the purchase because it seemed like a ridiculously good sale Was I really lucky here or is this normal?? It looks like it retails at 650 normally

Costco Casper Select (HELP!!) : r/Mattress
December 31, 2022 - The wife and I are not enjoying the Costco Casper Select. It is our first bed-in-a-box memory foam and we have had it for over a year or two now. We both are having back and neck pain that no amount of mattress rotating seems to help. I would say it is a bit too firm for side sleepers, maybe it would be better with a topper.
