When I first opened them up, they felt very thin and I thought I wouldn't like them.  However, after washing and sleeping on them, they are very nice and feel cozy.  They are not as wrinkle-free as I thought they would be for polyester.  I would have preferred the pillow case edging to be on the entire bottom edge vs. having the pocket on the back edge, so I will sew this pocket closed.  The extra set of pillowcases is a great feature.
