Memory foam mattresses need foundations that are solid with no “give” to them like that of a typical boxspring. BedInABox.com's American hardwood mattress foundation combines U.S. grown poplar hardwood and a high-quality quilted cover, to create a beautiful and strong foundation. Our foundation is kiln-dried, which won’t warp, crack, or split. It comes in an 8” profile with a 4.75” distance in between each slat, ideal for our memory foam mattresses. It ships in one compact box that can be easily moved through small spaces. Assembles in about 30 minutes.
