Very comfortable to sleep on, well-padded and cuts my king-size bed perfectly.  I like the fact that the gripper sides are a solid style of fabric, which I think will be durable and resistant to tearing.  My only qualm with the design is the square seamed pattern, which comes through the sheet and causes some wrinkling, which is a bit annoying.  But this mattress pad is well made, and worth the price I paid.
