Bought two of these, one king and one queen, based on favorable star ratings and comments. Though the top of the mattress pad appears to be comfortable and of good quality, the sides are made of very thin, paper-like material with elastics running thru them. When putting the queen on mattress, one of the elastic corners ripped right away. Called customer service and was emailed return shipping labels promptly for both pads for full refunds. I use Overstock.com regularly for many reasons; the products reviews are helpful (tho not in this case), prices are reasonabale and sometimes great deals are found, shipping is fast and convenient, and customer service has been great. I have had defective products in the past but have never had any trouble returning them.
