Q: Do I HAVE to buy new box springs when I buy a new mattress if my new mattress is the same size as the old one?

— D.M., Suffield Township

A: Maybe not, but it depends on the condition of your current box spring and the mattress you’re buying. Most mattress warranties require that a mattress be properly supported so it doesn’t sag and wear out prematurely. Consumer Reports says that as long as your box spring is structurally sound and appropriate for the type of mattress you’re buying, it should satisfy most warranty requirements. Nevertheless, some warranties require you to buy the company’s box spring to receive full coverage, Consumer Reports notes. It’s a good idea to read the warranty of the mattress you’re buying, just to be sure.
