"I actually had to hunt down the AirBNB we stayed at to find this mattress. We had tried 3 others and they couldn't compete... as a side sleeper, it's just as great for me and my stomach sleeping husband... I'd pay double for this bed." Karie

"After 2 nights on my new Casper mattress I'm sleeping better than in years. I haven't been able to sleep on my side for long periods...but now I can without pressure on my joints. I'm no longer waking up with body aches and soreness." Donna

Best mattress We love our Casper's mattress and always recommend it to all our friends. We don't have any back problems sleeping on it and every time we sleep somewhere else, we are always eager to come back home to our Casper mattress!

Survived being hit by a semi and is still comfortable! 20/10 I've had my original The Casper for about 10 years now. It's seen a dog, a couple cats, a cross country move. I've loved it the entire time. When my fiance and I started seeing each other, she became a fan of it too. It replaced her mattress in our bedroom when we moved in together. And it came to her parents house with us when she got sick with Leukemia last year. We've missed it dearly sleeping in the hospital the last 3 months. Now that her treatment has gone well, we've been excited to return home. In preparation for her return home, I loaded up our mattress in the back of my truck to move it from her parents house back to our place. Unfortunately, one of the straps I had tied it down with snapped, and it blew out of the bed while on the highway. Thankfully, no one was injured and no accidents happened. However, a semi did run it over and dragged it about 1/8th of a mile up the road before spitting it out. In one piece! The outer shell was in tatters, and the inner sheet had some tears. The only structural damage to the mattress was a medium size tear in the main layer of foam which I was able to stick back together with spray adhesive. I've since put a couple of outer zip encasements and sheets on the mattress, and we just had our first post cancer sleep on it. Still just as comfortable as ever! Thank you to Casper for making a fabulous product!

Perfect!!! We're so happy! This box spring is impressive & worth the wait! It was back ordered, but arrived quicker than expected!! It was packed perfectly, and wasn't hard to get up our stairs. Also didn't take long to set up, no tools needed and amazingly sturdy!!!

Frequently asked questions
Does The One memory foam mattress sleep hot? 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 you are a hot sleeper, 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.
Which is the firmest mattress in the assortment? The "One" is the firmest mattress type 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 affordable memory foam mattress experience. The One is firmer than our previous value model, The Casper.
I have The Casper and I wanted another. Which mattress should I buy now? 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 the best choice for anyone looking for an inexpensive mattress upgrade.
What kinds of bed frames are compatible with Casper mattresses? 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.
I need a split king base. Do you offer that? 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.
What is a mattress in a box? How long does it take for a Casper mattress to expand? 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.
