Update: Sept 30, 2016These are holding up very well. I just bought a second set.First, we washed them as soon as we got them. If you do this, which I recommend, Dry them on the LOWEST SETTING. My girlfriend didn't read the directions, and while we don't notice any negative effects, we hadn't use them before so we have no comparison.We bought the periwinkle. The color is nice. But the reason we love sheets is because of how soft they are. The Queen Size fitted sheet fit our pillow top queen mattress perfectly. The top sheet is long enough to reach the bottom of the mattress on both sides.I generally don't buy items from Amazon if Prime shiping isn't available. However, the bamboo cotton sheets with Prime were priced way too low to be any good and had the reviews to back up my assumption. These made it to SE Michigan in 4 days.I will update later if the quality comes into question after some use and washes, but these sheets are definitely a good choice if you are looking for bamboo cotton sheets. In fact, my only complaint is the same complaint I have about every sheet set I ever buy; Only two pillow cases. Who has only two pillows? Raise the price $20 and give me four!
