I was disappointed by this item. It says mattress cover in the description when in fact it’s a BOXSPRING protector. That’s an entirely different thing. It took two people to put this on the boxspring. It’s very tight and it zips all the way around so you have to start at the top of the boxspring and work it all the way down to the bottom. It was not an easy feat as with each pull it felt like the product was going to rip. The only plus is that it completely encases the boxspring so it definitely will protect from bed bugs or any other issues.
