i purchased this for a full size bed but, after ordering, i was concerned about the fit because i have to get deep pocket sheets for the mattress and thought maybe i should have ordered a queen size. To my surprise it fit perfectly over the mattress and down the sides; a queen would have been too large. very pleased with the product !!

Soft, fits great and not bulky

I wasn't sure if I would like this QUEEN SIZE waterproof mattress cover but I needed one asap that day. SIDE NOTE: I always forget how soft 100% jersey cotton is This waterproof mattress cover is very nice and super soft. This isn't going to be one of those thicker, plush type mattress pads. This mattress cover is more meant to protect your mattress from certain stains so you wouldn't want it to be plush. It fits great, and helps with keeping your mattress looking new. I recommend this queen size Mainstays Waterproof mattress cover protector. Good quality imo
