Fits smoothly
Size: Queen
I really like it. It fits smoothly with no wrinkles and no "crackling" noise. I have an older mattress that is not as deep as the newer mattresses and I have a hard time with new sheets being too loose and wrinkly. This mattress protector has all around elastic that should make it fit any size.

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.
