OkiFirm

$550

Graphite foam layers provide a firm feel with extra support.

High-density all memory foam, perfect for back and stomach-sleepers and those who love extra support.

Firm Feel

Our densest foam layers provide comfortable but solid support with little give to help with spine alignment and to protect from unwanted contouring.

Graphite Foam

10” of advanced graphite foam absorbs pressure to give you the proper support and relief needed for a great night’s sleep.

Sleeps Cool

Ice Yarn cover is cool to the touch, while the graphite foam with air holes creates a breathable, heat-removing mattress that lets cool air flow so you never overheat.

FAQs

Do OkiOki mattresses have a weight limit?
OkiOki mattresses were designed for a couple weighing 600 lb. Our mattresses are built for all different body types. Take our sleep quiz to see which mattress is best for you.

Does the mattress need a box spring?
You do not need to use a box spring, but you will need to use some sort of foundation. If you are not using a box spring you will need to use a bed with cross-slats, a bunkie board, or anything that will serve as a foundation.

Why do OkiOki mattresses need a foundation?
Every mattress requires a system that supports the entire underside of the mattress. A foundation is only required with a metal bed frame. Alternatively, you could purchase a bed frame with cross-slats that would support your mattress.
