Wasn't going to purchase a mattress pad, didn't think it was necessary - Very glad I did - it fits perfectly over my queen size mattress - no sagging or bunching, and the quilted pattern makes for a very comfy night's sleep! Should have gotten this years ago. It's almost like having a pillow top mattress - without the expense. Highly recommend this product, especially if you have an older mattress - I hope to get a few more years out of mine now.
