The Eight Mattress is best placed on a breathable box spring or breathable slatted base. If your foundation has slats, be sure there are no gaps wider than 3” between the supporting beams/slats of your foundation. The floor or solid wood foundation (without slats) is not recommended, as it may not provide enough breathability for the foam.
Check out our multi-functional Simple Foundation here, it works with all bed types and can even be used as a box spring.
