It is a sleeping system that is based on a spring-loaded frame similar to a mattress instead of a slatted frame. Boxspring means spring and essentially describes the structure of the base. The actual mattress then lies on top of the box spring, i.e. the base frame. However, since a mattress lies on top of a mattress, the double spring deflection results in excellent lying comfort. A box spring bed has an optimal entry height due to the relatively high construction and also looks very inviting.
