Mattress protector is a great fit. I had trouble finding cover to fit my thick queen sized I just had to go up a size. adjustable mattress.

exactly what needed. easy to put on the mattress

The important thing is it fit just fine - I had measured the mattress height at about 13 1/2 inches, so I purchased this queen size mattress cover with a height of 14 inches, and it fit perfectly. It did not make the bed any less comfortable to sleep on.
