Perfect fit for a 13" thick mattress. Didn't know about purchasing a zippered mattress cover but actually prefer it over a slip on no that I have used it.

Bought this to cover a new mattress for the guest room. It covered fine. Fit well. Doesn't crinkle too bad.

Excellent quality and value. Everything as advertised.

Great product, fits my mattress perfectly

Exactly what I needed. Fits my 14" mattress and doesn't crinkle too bad.

This item fits perfectly and is so well made Regards Michael

This was a perfect fit for my new mattress; would highly recommend.

Directions are present for installation; and there is reference to.machine washable & dry. However, even with low heat,(my call; no directions for that) the sides melted at first wash. Very, very disappointing. Where is information for "lifetime warranty?"

This mattress protector is really deep.

I'm giving them 5 stars cause they look like great quality. If I can ever figure out how they go on, I may give them 5 more stars. lol
