Well, this cover is remarkable. It arrived today, and although we doubted we’d actually be able to cover our box spring with it, the task was done in 7 minutes without removing our king mattress off the bed. We are in our 80’s, and had absolutely no trouble covering the box spring, even though the bed has side rails and a big footboard. Life has enough challenges, treat yourself to a product that will make your life a tad easier.
