King Single Size Mattresses

Need a little extra space to stretch out in? A king single mattress and base is just what you’re looking for! Bigger than a single bed but smaller than a double bed, it’s perfect for growing teens. It also works well in kids' rooms for sleepovers or for anyone who wants a spacious feel.
