Review on Everest Encasement Waterproof Hypoallergenic Zippered by Joy Anderson

2 sets of sofa mattress covers are offered. I ordered 54 x 75 x 6 inches as my son's full mattress was about 74 x 6.5 inches and the package received said 72 x 5 inches so I was really upset as I thought it was too short and narrow for a mattress was found, and cheap 6 -7 inch mattress covers are not easy. Most of these are for very thick mattresses and I don't need any extra material. I decided to try this on a mattress as these covers stretch a bit. My son's mattress is still in the plastic bag because I haven't moved yet and I tried it on over the thick plastic and it fit. The zipper closes tightly but not tightly. So if I remove the plastic it has a little more wiggle room :)) So happy I wasn't hoping for a refund. The mattress size for my son's bunk bed is about 54 x 74 x 6.5 inches. The material seems durable, but I can't confirm the water resistance, I followed the reviews. I hope it will be everything that is described as it is done at the expense of hospitality.
