Query: Lacking in Comfort

I just received a set of these sheets as a gift and was initially pleased to see that they were of 100% Egyptian cotton. I thought that was a good thing, but after sleeping on them, I'm not so sure.On the plus side, the sheet color is rich with a bit of a sheen. Stitching appears to be of quality, and I do like how nicely the fitted sheet fits. It's been a struggle finding snug fitted sheets since my mattress is of an average thickness. Hats off to Pinzon.But this is not comfortable bedding. The sheen gave the impression of a "sateen" feel, but not so. The cotton is rough, scratchy and feels like polyester. To be fair, they've only been washed once and could soften over time, but we'll have to see. Judging by how wrinkled they were coming straight out of the dryer, that may only be wishful thinking.
