We have a king bed that is the heaviest bed ever created. It’s 20 inches deep and must have a layer of steel in the middle because it takes 4 grown men to barely move the beast. This bag was a life saver in our last move!!! It went on easy, fit our 20 inch deep mattress like a glove (if your bed is over 20 inches deep don’t get it, this just barely perfectly fit) and the handles actually held up to lifting the bed! I was sure they were going to rip but man this bag is TOUGH. We won’t be moving again for many years, now it’s a fantastic GIANT storage bag. A+, well worth the money!!!
