What should I place it on?

Your 4Sleep mattress must be continuously supported by an adequate foundation or adjustable bed base with a proper bed frame sufficient to support the collective weight of the mattress, foundation and user(s). Failure to have a proper bed frame may void the warranty.

We recommend a platform style of bed that has a solid surface or a slatted base that has multiple, strong slats that are no more than 3” apart. A box spring can be used but we recommend a new box spring or foundation that is made to support memory foam mattresses. You will want to avoid older box springs that are not supportive and have a lot of open surface area where the mattress will sag. Your mattress will live a good life if it is resting on a firm, flat surface.

Do not use traditional metal frames that have no solid foundation on top of them. Do not use a metal frame to support a box spring or slatted system for a queen, king or California king if the metal frame doesn’t have a rigid center support rail. Ultimately, the more the surface area is flat and solid the better for the life of your mattress.
