What is the primary use of a boxspring? There are several reasons why you should use a boxspring, but among other things, it ensures good mattress ventilation. The mattress absorbs the heat and humidity we emit during our sleep. The boxspring allows aeration, preventing mold development and mite proliferation. It also acts as a shock absorber and extends the life of your mattress. Slatted beds do not require boxsprings because this system allows air circulation.
