A very thick and luxurious mattress cover that covers even the thickest mattress. Ours is 11" mattress and it fit with ease. The topping is nice and padded. The sides are deep and elasticized.Takes two people to install it on the mattress because it looks so shrunk before it's stretched out. BEWARE of the fabric label. CUT IT OFF BEFORE WASHING THE PAD! The label is plastic and it melted in the dryer and turned into a sharp, knife-like THINGIE sewn into the cover! Willl definitely slice the sheets if ignored. We had to use wire cutters to chew it off the mattress pad after it had melted.
