I actually had to hunt down the AirBNB we stayed at to find the mattress. We had tried 3 others and they couldn't compete. Very firm bed but as a side sleeper, it's just as great for me as my stomach sleeping husband. I know reviews state otherwise, but not having my hip sink 3-6 inches while the mattress stays level and firm is amazing. I'd pay double for this bed.

I love me all foam mattress. Simple as. I've been sleeping on Casper memory foam for 8 years now and decided to get a second mattress from them. While firm, it does have a decent amount of give to it that feels like it cradles you while you sleep. Very comfortable, even if sleeping on your side.

I have an original Casper Mattress, and purchased a One Mattress for another bed. The One is as wonderful and as comfortable as the original! It felt like my bed as soon as I laid down. My cat immediately got under the covers and slept like a rock. We joked that we were glad to buy the cat a new mattress. I suspect the same effect happens with dogs, ferrets, parrots, and any other cuddly pal!

I debated ordering this for about three months, but my mattress was getting so uncomfortable. I needed an upgrade. I read the reviews and chose this mattress and after four nights I am in love! Thank you so much, it is exactly as it was advertised, and I am very happy with my purchase.

I’ve slept on a Casper mattress for the last 7 years - best mattress ever. I just got the newer version of the one I had and it’s absolutely divine!! From the moment you crawl into bed, the mattress instantly cradles your body. Not in sinking, plushy way but in a soft tender feeling kinda way. It’s the perfect amount of pressure relief and coziness. It’s so worth the money, you won’t regret it. Thank you Casper for making my sleep hours restful which allow my dreams to last longer…

All of our mattresses are specifically designed to sleep cool. We run thermal imaging tests and sweat tests to make sure our mattresses feel nice and breezy throughout the night to keep you comfortable.
If sleeping hot is a challenge for you, Snow Technology is our most advanced solution to nighttime overheating. The combination of HeatDelete™ Bands, Phase Change Material, and cooling Snow Cover keep you comfortably cool from the moment you crawl into bed.
The “One” is the firmest mattress in our collection. It is an all-foam mattress made with Breath Flex Foam, Align Memory Foam, and a Casper Core. The One is firmer than our previous value model, The Casper.
If you loved The Casper, you'll love the upgraded One. This all-in-one sleep solution is slightly firmer but still has the signature Casper feel. The all foam mattress is made with Breath Flex Foam, Align Memory Foam, and a Casper Core
A mattress in a box is a mattress that’s compressed in an air-sealed bag and rolled tight so that it can fit into a box that’s easier to maneuver than a traditional mattress. Allowing you the flexibility of picking your mattress online and having it easily delivered to your door.
When you receive the mattress, all you’ll need to do is pull it out of its packaging, lay it flat on your bed frame or floor, and let it expand.
The mattresses can be slept on almost right away but may take up to 48 hours to expand fully. Our Snow mattresses are primarily made with memory foam and can take up to 72 hours to expand fully.
