I ordered this in twin and queen for two different beds.  The material feels thin but you cannot see the bed frame through it so that's a plus.  The corner's do pull and gap a bit but after some "fussing" with it, I managed to get them to lay flat and not gap.  It did wash easily and looked good out of the dryer.
It does what I need it to do.  

Pros: Washes easily, looks good once on and in place
Cons: Thin fabric, gaps at the corner a bit
