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.
