This mattress pad is true quality, the material that goes around the mattress is perfectly stretchy and is easy to put on. The cotton on top is true quality and I was so happy with my purchase. I bought two extra long twins for our sleep number bed that is a eastern king and they fit perfectly! I am so glad I did not spend $500.00 on the ones that the Sleep number store wanted to sell us. The quality of these far exceed the cost truly a great buy.
