Great Mattress Protector

I have bought this mattress for every bed in my house (3) and recommended it to everyone else. Doesn't matter if you have littles who are accident prone, it's just one more layer of protection on your very expensive investment!

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

Good Quality

This cover seems to be of good quality and it fits perfectly. Not thin or flimsy feeling. Glad I didn't spend money on a more expensive brand! Highly recommend.
