We get this question quite a bit. Whether it’s a futon frame (used only with our mattress in the pulled down flat position) or a slatted platform bed (wood or metal), potential customers have asked whether these options would work with our mattress.
Slatted foundations can be appropriate as long as they have sufficient slats. As a rule of thumb, we generally find that the slats that work well are about 3″ wide or so and about 2″ – 3″ apart. So a queen slatted foundation or platform would end up with 12 or 13+ slats.
There are some newer metal frames that allow storage underneath that I often get asked about as well. And I’m skeptical about these, even though they are sold as compatible with memory foam mattresses, since the metal framing that the mattress sits on has such thin metal pieces (the metal “slats). While they have fabric that then goes on this metal structure, I am concerned that this still doesn’t provide that firm a base for the mattress, and also that over time the thin metal frame pieces may dig into the foam even through the fabric cover.
