Why We Love It

I love that the top feels smooth, kind of like a soft, woven tee

It has a pretty solid bounce when I push on it, even though it's on the thinner side

I like that the edges feel firm when I press down – doesn’t sag at the sides

About This Product

Hot sleepers, meet your mattress jackpot: a medium feel design that pairs cooling comfort with dependable support. Crafted with a medium level of firmness, this mattress combines cooling technology and durable construction for sleep you can count on. On top, gel-infused memory foam cushions pressure points while drawing away heat for refreshing comfort. Beneath that, a second layer of gel-infused comfort foam enhances breathability through the night. A sturdy base foam layer grounds the design with lasting support, so your mattress holds strong over time. Finished with a soft, breathable knitted cover, it’s thoughtfully crafted to deliver cool, comfortable, and reliable rest night after night.

Very soft and comfortable. Makes it easy to come off the bed. No back pain or trouble sleeping. I bought it for my toddler but I’ve been sleeping on it with her ever since. Came pretty fast as well!

This mattress is so comfortable and the price was very reasonable. I loved that it came in a sealed vacuum and was easy to carry.
