When I was shopping for a mattress pad I looked everywhere, on and off line. This Croscill 500 tc Pima Cotton Dobby Check Mattress Pad is even better than I expected!! I am 52 years old, and I've never had one that stayed on the mattress as well, or was this comfortable! I saw pads at other stores that looked like this one, only they were two to three times as much. We have a new thick mattress plus a four inch memory foam pad and the Croscill 500 tc Pima Cotton Dobby Check Mattress Pad has no trouble staying put!!!!!
