What is the purpose of a box spring?
The purpose of the box spring is to help raise the mattress so that it is easier to get in and out of bed. Another purpose of the box spring is to help absorb the weight of anything that is on top of the matress. It also reduces the wear and tear of the matress. And it also gives a flat surface to put the matress on so that it does not sag in certain places. It is usually made with a wooden frame that has metal springs inside.
