Very comfirtable
Size: Twin XL
With all the great reviews, I chose this brand mattress cover and am so glad I did. The cover went on easily, fits snugly and Stays on the mattress. Even tho the cover is not thick, it certainly makes a softer yet firm foundation to sleep on. There was no odor and no change in temperature. I think it is well worth the price.

Protects your mattress from toddler spills!
Size: Full, Size: Full
Writing this after my toddler spilled a ton of water on my bed (a new mattress). I didn't realize what she had done for about 1 minute. By the time I got her off the bed, pulled the sheet off and pulled the mattress protector off, the mattress was still dry! I felt the bottom plastic part of the mattress protector and could feel the coolness of the water, but not dampness. This thing works! Note, I don't know how it would perform if I had left it for a really long time. The protector is also very soft on top, not noisy, and easy to stretch over the mattress. You can kind of see the square shapes of the protector through the sheet, but I personally don't care. It was a great buy.

Great Waterproof Mattress Protectors
Size: Twin XL
These are very nice mattress protectors. I purchased the x long twin size for my California King Bed. I like the feel of the quilted cotton top and they fit my extra deep mattresses just right. they washed and dried well.
