We are very pleased with these sheets, they are lightweight and not hot at all (big factor, and one micro fiber sheets usually fail at). They come out of the dryer wrinkle free and look nice on the bed - BUT they are made for a very deep mattress, if you have a thinner mattress they tend to bunch up making it messy looking and uncomfortable. I purchased this set to fit a hospital bed covered with a deep memory foam topper). This is common with sheets sold now, for some reason they are all made to accomodate thick mattresses. To fix this I turned them wrong side out and stitched a "dart" in each corner, reinforcing it several times after making sure they fit well - now they fit beautifully. I can't complain that they are for a deep mattress, as that's clearly how they are described, but I didn't realize how deep they would be (my fault). As far as durability we've been alternating between using these and a cotton set since October and these are his favorite and still look brand new. I recommend these without reservation - my son wanted sheets and I sent him a set of these in queen size gray color - they fit his bed well, and he loves them (and it's August in Florida- the best test there is to see if sheets are cool and comfortable to sleep on!)
