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 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."
"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!"
"When this Casper Snug mattress arrived it was immediately claimed by my kids for a movie party and gymnastics crash pad! My 7 and 4 year old both claimed it felt so cozy they wanted to take a nap on it right there. We have now used it for a full week with our oldest and it seems like it’s a perfect balance of support and cushioning. He’s falling asleep faster, and seems like he’s waking up for school more quickly and rested. It was extremely easy to set up (for a twin sized mattress) and the included mattress protectors already came in handy when some water bottle leaking happened at bedtime! We’re particular about our kids’ mattresses and mattress protectors so they don’t end up too hot at night, and they both seem like they’re doing a great job of regulating temperature at night. Overall it’s a winner!"
"We were so excited to receive the Comfort Snug in the mail. My son (7) was previously using a traditional spring mattress. He has always been a low sleep needs kid, but we noticed he started sleeping less and less, was always tired in the morning, and had a harder time falling asleep at night. One week with the Comfort Snug and that has all changed! He's now falling asleep quickly and waking up feeling refreshed. I was pleasantly surprised with how comfortable this mattress is. Set up was incredibly easy, all we had to do was cut off the plastic and wait for the shape to form, which only took about 45 min to fully form. There was no smells to the mattress either which I feel like you often experience with memory foam. The mattress protectors worked as expected, my son ended up spilling his water and nothing got through to the mattress. Changing out the mattress protector and sheets is super easy, the mattress feels relatively lightweight and it is an easy one person job. Overall I think this is a fantastic mattress for kids and young adults!"
"We recently upgraded my 3-year-old’s bunk bed mattress to the Casper Snug, and I truly didn’t expect it to make such a noticeable difference but it really did! She was already sleeping in this bunk bed, so this wasn’t about a big transition, it was purely about comfort. And the Casper Snug is such an upgrade. It feels supportive but still soft and cozy, and she immediately noticed. Bedtime has been smoother, she settles in faster, and she’s been sleeping more soundly through the night. One of my favorite features is the low-profile design. That was really important to me for a bunk bed. It fits perfectly without sitting too high, which makes me feel more comfortable from a safety standpoint and keeps the bed looking proportional. And the mattress protectors have been a total lifesaver. We’re in the middle of nighttime potty training, so protecting the mattress is non-negotiable. I love that the Casper Snug comes with two protectors so we can rotate them. If there’s an accident, I can quickly swap one out for a clean one so I don’t have to worry about damaging the mattress. It’s one of those upgrades that makes everyday life easier. More comfort for her, more peace of mind for us, and a perfect fit for a bunk bed setup."
"The Casper Snug mattress has been such a wonderful upgrade for my daughter. It offers the perfect balance of comfort and support, soft enough to feel cozy, yet firm enough to provide great structure. She was absolutely thrilled when it arrived and couldn’t wait to try it out. She says it gently forms to her body and feels like it hugs her just right. Since switching to this mattress, we’ve noticed a positive change in her sleep. She’s falling asleep more easily, staying in bed through the night, and even sleeping a little longer than before, which has been a huge win for all of us! Setup was incredibly simple. We unboxed the mattress and let it expand for a few hours before placing it on her bed. It fluffed up quickly after being removed from the box, but we gave it a little extra time just to be safe. It fit her bed perfectly and was ready to go the same day. I was pleasantly surprised to see that mattress covers were included. That was such a thoughtful addition, especially for a child’s bed. They’re easy to put on, simple to remove, and make cleanup so much easier, a smart and practical feature for families. Overall, we are extremely happy with this mattress. I’ll definitely be looking into upgrading my other kids to the same one over time!"
