This is a very high quality set for an insanely reasonable price. Very high quality, beautifully made.. The underside of it is a nice soft cotton as stated and the side you see in the picture is a heavier material with a sheen to it. It's not a bright red but more of a burgandy color. Very rich looking with beautiful matching pillows and bed ruffle. My husband who is picky as anything loved it. I've looked at many sets and this set is as nice as sets I have seen for four times the price.
