Kids Premium Foam Mattress
Little dreamers need big rest.
Long-lasting materials and a pair of waterproof mattress protectors give you peace of of mind, while three layers of breathable, supportive foam gives them the deeper sleep little dreamers need.
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?
STAY DREAMING: Three breathable layers of foam with a little bit of bounce keep them asleep, so you can be too.
FEELS JUST RIGHT: A balanced, medium firm feel is both supportive for growth spurts and easy on growing pains.
PREPARED AND PROTECTED: Includes two five-sided waterproof protectors to guard against everything (except nightmares).
GET COZY: Wrapped in a soft knit cover to make bedtime extra comfy.
SHORT AND SWEET: Low profile makes it easy for little ones to get in and out of bed (and perfect for bunk beds, too!)

Our 6 year old immediately said "ohhh so comfy" when she snuggled up on it for the first night and has been falling asleep faster and having more restful sleep since. And the little one having more restful sleep means we all do.

Snug™
The 8 inch height is perfect [...] we have it on the top bunk and it’s still very safe! The weight getting up in the top bunk was so much better than the mattress it replaced. Getting it out of the packaging was very simple and it came to true size very quickly.

Snug™
We transitioned from a toddler bed to a twin sized bed and this mattress has made bedtime so much easier! My child went from stalling and refusing naps and bedtime to wanting to go to bed, even if it's just to relax there and play with her dolls.

"I would not recommend in cases where the parents still need to get in bed with little ones. Its not very comfortable."
"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."
"My son absolutely loves his new mattress!"
"My 3 year old absolutely loves his new casper mattress!"
"Works great :) so comfortable!"
"Got this mattress for our daughter’s big girl bed and it was a great addition to her room. Super comfortable and cozy!"
"So comfortable! My toddler loves this bed. The lower profile height is perfect. Fits a standard twin sheet just fine."
"The Casper Snug has been perfect for my daughter’s bunk bed. Her last mattress was much too thick, her head nearly hit the ceiling whenever she sat up. The low profile of this mattress is ideal. My daughter loves it too. She says it’s the most comfortable mattress ever, and seems to be sleeping beautifully on it. As a mother of multiple little ones, I love the protector feature. When kids are involved, accidents and messes are guaranteed. When those messes do happen, the protector allows for quick and easy cleanup without the worry of a ruined mattress. My other daughters are always wanting to try the mattress for themselves. The kids love it, little and big alike, so I love it too."
"I can’t say this mattress has made a huge difference in my kiddos bedtime routine yet, but I have definitely been enjoying bedtime MUCH more! It’s way more comfortable than his previous mattress, so I don’t end up super uncomfortable while trying to get my toddler to sleep. Plus, he HAS been staying in bed a little longer! I’ll take that as a huge win! Unpacking and setup was a breeze. It unrolled easily on his bed frame and was ready within minutes. The mattress protectors are easy to slip on and take off. They work well, and having two is a game changer! No more waiting for one to be done in the wash before remaking the bed. Every little bit of time savings helps a ton with littles."
"Me and my little one have loved the Snug mattress! To start, setup was a breeze! The mattress came very protected and to my surprise, was ready to go in minutes!! The mattress protector fit perfectly and we were on our way to set it in her bed frame! The mattress is so lightweight! I was able to lift and carry it down the hall solo to put in my daughter’s room. She has a daybed and it is the perfect height. She slept SO well from her first nap she took in her new big girl bed! We use a sound machine to tell her when she can come out of her room and I think if we didn’t turn it off, she would have slept even longer. She has told me several times “My new bed is so cozy!” My daughter is 3 and between this mattress and her bed, it is the perfect height for her to get in and out of with confidence! I expect many more restful nights in the future!"
