How Often Should I Replace My Boxspring?

Replacing Boxsprings

Boxsprings act as support systems for your bed. They should be replaced every eight to 10 years on average, which is slightly longer than the recommended eight-year lifespan of mattresses. However, major defects like sagging or broken slats mean it's time to buy a new foundation sooner. Also, since mattresses must sit evenly on boxsprings in order for them to be properly supportive, the purchase of a new mattress may warrant a replacement boxspring, as well.
