Hybrid

This traditional-feeling mattress has body-contouring comfort and a bit less sink—to ensure sweet dreams ahead.

The ins and outs
Inside my hybrid mattress are individually wrapped coils that give you lots of support (and let you sleep peacefully if your partner moves). And I topped it off with comfort foam layers that help with pressure relief!
How it feels
Hop on, and you'll feel a nice balance of comfort and stability with a slight bounce!
Is it your match?
If you or your partner tend to change positions a lot, you'll benefit from the support of the individually wrapped coils that let you move around easily.

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.

Sleeping great now.

#SweepstakesEntry 3rd time is the charm. We tried a few different mattresses over a few weeks and the treasure king was the most comfortable for us. Bobs was a great place to work with. All the reps were great. We wouldnt go anywhere else.

Review For My New Mattress

#SweepstakesEntry - I slept on a sleeper sofa for almost a year. I now have a full extra firm mattress and my body is thanking me everyday since.

Seth on a cloud via Bob!

My stepson is floating on a cloud. He has never slept better, been more well rested, and had an overall more meaningful existence.

Mattress and base just right

Great mattress and power base! Very comfortable yet supportive. This is in a guest room so needed something that everyone would like. Not too soft yet not too firm as well. Base is icing on the cake! Can raise head or feet. Great for snorers!
