Aches and pains? Night sweats? With our most supportive ergonomics and enhanced Snow Technology, including QuickCool™ Cover, Snow Max is the ultimate solution for whatever is keeping you up.
Which mattress size is right for you?
When picking your next mattress, it’s more than just personal preference—two key things to keep in mind are how much room you have and who’s sleeping in the bed.
Upgrading to a King mattress is a game-changer if you’re sharing space with kids or pets. And if you’re tall, the extra length of a California King could be just right.
A Full size mattress is ideal for young adults or those with a smaller bedroom, while a Queen is the top pick for couples or anyone who enjoys extra space to sprawl out.
The Twin is the smallest option, ideal for single sleepers. While the Twin XL is a dorm favorite it can also create a Split King if you purchase two.
Which pillow size is right for you?

Real feedback from customers who have experienced the Casper difference.
I hadn’t slept well for quite a while and always felt our old mattress may have been a factor. All I can say is, my sleep tracker keeps congratulating me on meeting my goals.

Snow Max
My partner and I had been sleeping on a mattress that hit the end of its lifetime and constantly woke up covered in sweat and filled with back pain. The snow max is a complete game changer. No more back pain or night sweats.

Snow Max
We decided to try a luxury eco-friendly mattress and it was a painful mistake. Switched the Casper Snow Max. The pain is now gone and we sleep much better overall with the “snow tech” (heat sink) bands.

"We purchased this mattress based on the reviews and could not be more happy! I am a side sleeper, and my partner is a back sleeper and it fits both of us perfectly. It’s firm around the edges and the areas that are important and it has some give in the areas like shoulders and hips where you need it. I’m 55 years old and have purchased many mattresses over the years and this is by far the best! Two months in and very happy."
"The jury is still out since we are only 2/3 of the way through our 100 day trial. There is no question that the Snow Max provides firm yet comfortable support. However, I sense that we wasted a lot of money anticipating that the mattress with its built in cooling cover would actually keep us cool. I’m a relatively stationary side sleeper which means I don’t move much over the course of the night. When I first hop into bed, it is actually cool. However after about 20 minutes that cooling has ceased. There are many mornings I wake up perspiring. So, bottom line the Snow Max fails miserably in living up to its cooling claims."
"I received this item, promptly filed for return (not due to quality, I have always loved the mattresses), the courier picked it up about 1 week later, printed the label in front of me, put it on the truck in front of me and then - POOF - there is somehow NO record of it being picked up and I'm not being refunded. It's been a frustrating experience."
"It has been a challenge just to get the order correct and sent as I got the split twin and not the one solid piece. One side of the “Snow Max’ that side that someone else sleeps on after asking them and seeing it for myself seems melted? Like some rough stain has already got there in short time"
"My wife and I upgrade mattresses every time we replace. The CASPER SNOW MAX is the best we've ever slept on - by far. Better than any hotel, luxury cruise, our previous Avocado. The soft conforming top - wonderful. We love it. So does our spoiled old dog."
"I have MS and so far the bed has helped with that my only complaint is that I thought I purchased the cooling one but that doesn’t seem to be the case."
"Great mattress, firm enough for good support and still feels soft and comfortable. Keeps you nice and cool while you sleep as well."
"Absolutely obsessed with this mattress. Set-up was easy, and it is SO comfortable. The cooling bit is definitely a plus as well! I'm so happy I made this investment in my sleep. I'm a Casper girl for life now!"
"I have the mattress a littleover 30 days. It is extremely comfortable and I ususally fall asleep quickly and stay alseep. At this point, the issue I have is related to my hips, both of which have been replaced. When I get up in the morning there is pain and stiffness in both sides of the butt at the hip area with some pain down the back of the legs, which usually goes away a little time after rising and moving around (but with some difficulty). I believe this may be due to the extra support provided in that area of the mattress to which my body is not accustomed. I hope this will improve during the remainder of the trial period because, as I said earlier, I really like the mattress. With regard to the question below where I picked "Varies" I would say mostly back sleeper."
"The Snow Max is okay, but I would have preferred a little more bounce."
