Memory Foam

This fully foam mattress conforms to your body and reduces pressure points, so you can catch some restful Z’s.

The ins and outs
I've paired my one-of-a-kind Bob-O-Pedic Memory Foam on top with a supportive foam base that isolates movement and reduces bounce.
How it feels
You'll feel yourself sinking in (but not that awful quicksand feeling). It feels more like a full-body hug.
Is it your match?
If you like a body-contouring feeling, memory foam is for you. It's also a perfect choice if you or your partner move around a lot, since it's great at motion isolation.

Different feels for different needs

Comfort feels different for everyone, which is why I've got options for you and your sleepy self. Browse below for better snoozing ahead.

Comfy but sleeps hot

Very comfortable bed but it sleeps VERY warm. I’m waking up sweating during the night (you can feel the heat being retained in the mattress) which was not an issue with previous mattresses.
