Should I replace my foundation when purchasing a new mattress?

A good fully sprung foundation is as important as a good mattress! It acts much like a large shock absorber, taking a lot of the nightly wear and tear. And it contributes to your comfort and support. Don’t put a new mattress on an old foundation. When you select the mattress, purchase its companion sprung foundation — the two are designed to work best together. Sealy engineers invented “foundation support” in the 1970’s, which sets the standard for today’s bedding. Don’t put a mattress on a ‘firm’ or ‘hard-top’ base – it slashes mattress life and substantially reduces comfort.
