Most “Box Springs”, traditionally found under your mattress, can’t technically be called that anymore, because they don’t actually contain any springs. We call these new spring-less frames “Foundations.”
Foundations won’t absorb as much shock as traditional box springs, but there are still quite a few good reasons to have one under your mattress.
Why invest in a Foundation or Box Spring?
It gives the bed more height. If the bed is too low, you’ll have a harder time getting into it each night.
Another height bonus: Your bed won’t look the same without a box spring. Bedrooms look more natural with a bed at the proper height.
Mattresses are built under the assumption there will be a box spring or foundation.
It gives the mattress a stable and flat surface. The body needs a straight plane to lie on to avoid spine and breathing problems
It reduces wear on bed frame slats. Without the foundation, a mattress will sag in the middle which can cause similar sagging in the bed frame slats.
