Rated 3 out of 5★ by 77reviewers.
Rated 4 out of 5★ by Cheap but works Yes its cheap vinyl, but it covered my queen pillowtop mattress with a little bit of play left.Now here is the big TIP. I went to the "Original Mattress Factory" show room and bought one their plastic covers they use to ship their matrresses. A nice thick gauage plastic for $5. Use the Mainstay 1st then cover it with the plastic and now you got a tuff little cover for a total $17.Any mattress showroom should have those shipping covers. The one I chose is very close to my residence. BTW, just as I zippered the mattress shut, the zipper broke off, LOL, but its sealed. SO DONT over do the zipper 06/04/2013
Rated 1 out of 5★ by Not for Me!!!! I bought 2 of these to use on new mattresses that I bought for my boy's bunk beds. The minute we tried to slide the top on in place this cover tore from one end to the other. I didn't even attempt the second one. The plastic that came on the mattresses was a better quality then these. 08/21/2013
Rated 1 out of 5★ by Bad product This cover is very cheap, but is also weak. 05/08/2013
Rated 1 out of 5★ by waste of money! We bought this Mainstays mattress cover in the queen size to put on the mattress in our camper. What a waste of money! My husband and I read the reviews and thought maybe the people who complained about it tearing were being a little rough with it. It is just plastic after all. Boy, were we wrong! We were very gentle in the way we handled the cover but, still it ripped, a lot! I refused to buy another one so I used duct tape to patch it (It's just for the camper and no one will ever see it). So for what it's worth, save yourself some money and buy a better mattress cover or, just get a plastic drop cloth and some duct tape and make your own cover ( either way it will be better than buying this garbage). I would give this product a - star if I could. 12/14/2013
Rated 1 out of 5★ by Cheap and weak 1st mattress cover ripped on trying to put it on mattress2nd mattress lost zipper.This should not be sold. Really bad product 11/10/2013
Rated 4 out of 5★ by Perfect for my needs I just need this to keep the mattress protected for my little ones who are transitioning out of diapers. This has been perfect for us. The price is right, and the mattress is protected. My child's bed is also his favorite play area, so eventually there was a tear in the plastic in a heavy-traffic area. :) I just covered it with duct tape and we've been good for a while. 07/02/2013
Rated 1 out of 5★ by This is made very cheap! And it tears very easily if you are not careful. And it also makes the crinkly noise everytime you move around. 05/17/2013
Rated 1 out of 5★ by For the price paid- not made very well. The zippers broke off of all 4 covers purchased 07/11/2013
