Received this yesterday and attempted to put it on the king mattress.  It was a very difficult project.  Our mattress is very thick and very HEAVY.  Nearly 90 minutes later it was on the mattress.  When I need to order another waterproof mattress cover it will be one that can tucked under all  four (4) corners of  the mattress.  Never one like this. It was very difficult to pull the cover on the bottom of the mattress because it was too heavy to lift.  It was also difficult to zip it because the bed is so wide that our arms were barely long enough to reach the middle of the bed.  The product is very well made and it feels very silky.  We are going to cover our queen mattress tomorrow. That should be much easier because we can stand that mattress upright as the king was ever so heavy.

Pros: Great value and a great cover
Cons: Very difficult to slide onto the mattress due to the heaviness of the mattress.
