This cover is a hit with everyone! I purchased it because the mattress on our King-sized bed is firm. I'm talking about solid ground here. I'm not joking or exaggerating in the least! My husband has never slept better, but I haven't. So I did some online research and decided on this one based primarily on customer reviews and price. It perfectly and securely fits my bed. I've never had to redo the straps in the corners. It's well-made, soft, and comfortable. Perfect fit, excellent value. Excellent for my backside!
