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

    This mattress is very comfortable

    This mattress is very comfortable and sturdy. The all foam felt very dense while this hybrid style, foam and coil springs, brings a nice blend of stiffness and cushiness. It was a great upgrade to the mattress we previously had. Let’s hope the softness lasts and mattress hold up for years to come.

    Mattress

    My Mattress is very comfortable. I just wish I would've ordered 14 inches instead of 8 inches. Delivery was on time and the Delivery men were very nice. Thank you
