Great sleep you can both agree on.
A Split King is a Win-Win
Some couples enjoy quieter, more restful sleep on a split king bed, especially when they have different sleep schedules. Our adjustable bases have presets to help boost lumbar support and reduce snoring, plus a restorative massage feature when you upgrade to the Adjustable Pro.
Considering a Split King Setup?...and because of his bad back, none of them were working well. We just got our Casper mattress about a month ago and could not be more pleased. So far, he’s been sleeping soundly without back pain.

The hybrid snow mattress is everything I wanted in a bed. My fiancé and I are both hot sleepers and it has kept both of us cool. Everything was super easy to set up and no foul odors when we opened the mattress for the first time.

Snow
Shipped extremely quickly and has approved our sleep quality immensely. I'm a back and side sleeper. My partner is a stomach sleeper. And it's been a joy for the both of us.

Dream
The perfect mattress for my wife and I. Any movement from either of us does not affect the other person. The perfect balance of softness and firmness.

Dream Max
Upgraded our 6-year old Casper that we had bought from Costco to the split-king Snow Max, one of the best purchases we have made in a long time.

Snow Max
I gave up a Sleep Number for a Casper Dream Max and couldn’t be happier. We both sleep so much better. The comfort level is so much better and the adjustable frame provides perfect sleep positions.

The best mattress for couples with a restless sleeper is one with strong motion isolation, meaning movement on one side doesn't transfer to the other. Casper's hybrid mattresses use a combination of high quality foams and individually pocketed spring coils that absorb motion at the source, so a partner getting up at 4 am is far less likely to disturb the other.
The Casper Dream and Snow Hybrid are both specifically engineered for this, with the Snow offering the added benefit of an all night cooling mattress.
Traditional innerspring mattresses transfer motion easily, but modern hybrid mattresses, which pair individually wrapped coils with foam comfort layers, isolate motion significantly better. Casper's hybrid models use Flex Coils that move independently, limiting cross-mattress vibration.
While Casper's all-foam mattresses still hold their own in pure motion absorption, our hybrid mattresses add better edge support, airflow, and bounce, features that many couples prefer.
The Casper Snow Hybrid is the best option for couples who run warm, thanks to our QuickCool™ Cover, Phase Change Material and Heat Delete bands that keep you 5° cooler than the Dream.
While our all-foam mattresses are made with breathable layers, our hybrid mattresses combine open-cell foam layers and coil base that allow continuous airflow throughout the night.
A medium or medium-firm mattress is the most widely recommended option for couples with different sleep styles. Casper's hybrid mattresses balance pressure relief for side sleepers and provide enough support for back and stomach sleepers. Our zoned support system delivers targeted firmness where each body zone needs it — softer under shoulders, firmer under hips and lower back — which helps accommodate two different body types and sleep positions on the same mattress.
The Casper Dream sits in the medium range that works well for most mixed-preference couples. If you’re in need of additional support, the Dream Max and Snow Max are our most supportive mattresses ever and have earned endorsements from the American Chiropractic Association.
