The purpose of a bed skirt is to give a stylish appearance to a bed without exposing the sides of the box spring or any space under the bed that may be used for storage.
The bed skirt should be approximately one inch from the floor. If it is more than one inch from the floor, then any contents hidden under the bed will become visible. Leavinâ¦g approximately one inch from the floor allows the space under the bed to benefit from air circulation.
