Great product! I was ready to give the new bed frame we recently purchased to my sister, because with its iron side rails our smaller box spring made it too difficult to make the bed. Then I saw this, and thought it might be the solution. I was right! Not only that, but the quality covering on this product by far exceeds that of our original (which was included with our $$$$ mattress!). The king-size came in a surprisingly small box, and assembly was a cinch. I would highly recommend! (Photos show both box springs, with this one on the bottom, because it’s sturdier. The color matches so well there is a very subtle line distinguishing the two.) I’m so happy to be able to keep our new bed!
