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…

I was a little skeptical of this mattress because it came in a small box. But once it was opened and fluffed out, I knew it was special. It is thick, durable and has the perfect balance between firmness and softness to sleep comfortably. 10 out of 10, I’d definitely recommend!

My wife and I have ordered the Nectar, we returned it, it sank in too much and we were falling into each other. Also way too high up. We ordered the Purple, we returned it, it was way too hard, took forever to warm up in, also too short, not thick enough. Then lastly, we ordered the Casper One, we are keeping it! Yes it is the most expensive of the 3 BUT only by a couple hundred and it is worth the extra money. And worth not having the hassle of returning the other mattresses and have them picked up. This mattress is the perfect height. Perfect combination between supportive and comfortable!!! Just order it.

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 for those seeking the best memory foam mattress experience at an affordable price. 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, making it an excellent choice for anyone looking for a memory foam mattress upgrade.
Casper mattresses are designed to work on a firm, solid surface like our foundation, platform, or adjustable bed frame. Having the correct support ensures the performance and longevity of memory foam mattresses.
For slatted frames, we recommend using bed slats that are flat (not bowed), wooden, and no more than 4 inches apart.
We do! For those who aren’t familiar, a split king basically means the frame comes in two parts. With an adjustable base, the two parts are able to work separately or sync together — so you can use the base with two twin XL mattresses or a single king mattress.
Our Cal king adjustable base is also split, but can only be used with our Cal king sized mattress.
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 and convenience 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.
Foam and hybrid 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.
