My friend bought one on the recommendation from another friend. He hates it cause it’s too soft. If you are a tall or slightly heavier person, I don’t think you’ll enjoy it in the long term. Our other friend who likes it is half a foot shorter than the friend that hates it. Answer from Special-Cat7540 on reddit.com

r/Costco on Reddit: Casper 12” select for $300?
March 2, 2024 -
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

Others have shared that the Casper Select has been marked down for clearance, and suspect there’s a new Cooling mattress that’s been spotted that will be replacing it (link below). Did you find yours for $299.97 or $300.00? Casper Queen mattress for only $299.97 Casper Select King Mattress marked down to $399.97. New Casper Select "Cooling" Mattress Spotted

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.

I bought the same mattress back in February. The tag showed it was in the box for over 4 months, which concerned me. And two of the corners were slow to fully inflate. But I gave it a couple weeks and have been mostly satisfied. A little more plush than medium firm, but I do enjoy the zoned support. Maybe not the greatest edge support. But sleeps cool and comfy. Hopefully it holds up long term. But don’t have to worry too much with Costco’s return policy.

Congrats on the upgrade! Sounds like a total game-changer—no more back and shoulder pain, no more awkward ridge, and finally, real support. That’s what good sleep is all about! Just a quick tip: be sure to follow the care instructions for your new mattress to a T. It’ll help it last longer and keep feeling as amazing as it does now. Rotate it as recommended, keep it properly supported, and use a mattress protector to keep it fresh. Enjoy the better sleep—you both deserve it. Sleep well and catch all those ZZZs!

Casper Cooling Select Review
The Casper Cooling Select mattress is a Costco-exclusive 12″ foam mattress made of poly foam, memory foam, and a support foam base. It has a thin cover and is designed to create more of a floating feel, as opposed to sinking down “in” the mattress. It has minimal sinkage and low levels of bounce. This limits the amount of contour and hug the mattress provides and helps prevent sleepers from sinking too deep. The Casper Cooling Select is available in a single firmness... 7.93 Overall Score

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
