We recommend that you purchase a new foundation when you buy your new mattress. It may seem like using the old box spring is an easy place to realize some savings, but that’s not the case in the long run.
A mattress and box spring age together. An old foundation has developed flaws right along with its original mattress. These flaws can transfer through to any new mattress placed upon it, causing the new mattress to break down faster. Investing in a complete set up front saves you the trouble of having to buy another mattress prematurely.
