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.

    Enjoy the Journey

    Buy the best bed that you can. Your body needs restorative rest. For me, that was the Power Bob Elite Base with Treasure 12. 5” Queen Pillow Top Plush Mattress and it feels like being cuddled in luxury! So comfortable, head/foot adjustments to find your sweet spot!

    Works
