Spahr Bedding Bed Bug Mattress Cover - Zippered Encasement Mattress Protector- 100% Waterproof, Hypoallergenic, Breathable Protection - Twin Size

It fit fine and has amazing feel to it, even under the sheet. The only thing is, the thread count is so high that I had to leave the zipper open a couple of inches so the air could escape faster.

These are great, just make sure you air dry them in the dryer with the zipper open so both sides can dry. Great quality.

I know I always check reviews before purchasing most anything, so I'm writing this one to possibly help someone else. This mattress cover is a thing of beauty. The fabric is top quality and it fits my queen mattress like a glove. One thing -- it would be helpful to have another person assist you, although I did it myself in about 20 minutes. The zipper is on the end and the opening is plenty large enough for the bed, but it requires a little effort switching sides by yourself to move the cover all the way to the end of the mattress. I highly recommend this cover!

Easy to put on. Looks like it will last and do the job. Would recommend without hesitation

It's ok...not that great. Zipper broke off the 2nd time I zipped it shut and I've only had it for a week or so... It's tight on my 9" mattress plus 2" foam topper. Really doubt it would fit anything larger than 12". Don't why it has so many 5 star reviews, suspicious.

I would probably love this if the zipper didn't come off in my hand the 1st time I put it on...now I'll have to cut/rip it to get it off...very upset since I was using it for a new mattress that I'm also seeing issues with immediately after delivery; I may have to return them both:(

Waterproof, yes. But odors get through to the mattress. And it doesn't take long. I had this mattress cover on my bed when my dog had an accident (on top of the bed, to be clear, not on the sides where there isn't any plastic). Although the liquid didn't manage to reach the mattress, the odor did. I then had to use arm & hammer to get the scent out of the mattress (or cover it up -- I'm not sure which). Never again would I purchase this product. It does not offer enough protection. Buyer beware.

I was interested in getting a mattress pad that made my bottom sheet fit tight and staying that way. So far, I really like this purchase.
