I gave this set 4 stars because of the fitted sheet, which fit the mattress perfectly even with a 1.5" layer of memory foam. That's what I wanted the most out of this set since I haven't found any other fitted sheet to fit this mattress. I deducted one star because the flat sheet is too narrow for a queen size sleeper sofa. There is only about 3" clearance on each side. I will go out and buy another flat sheet to replace it with. The cotton is fairly soft and smooth. Wish they made this in flannel and/or different colors.The sheets themselves are nice but the fitted sheets pockets are 12" and not 6" as the description says. I was specifically looking for very shallow pockets so they would fit tighter on a thin foam mattress. I had to return them because they wouldn't be any snuger than the sheets I have now which I hate. These are regular sheets and not suitable for a sofa bed or a thin foam mattressThe sheets fit fabulously, material was cool and comfortable. The only problem was that the pillow cases seams were not sewn well.Nice quality and great fit.It seems like the depth of the fitted sheet was for an actual bead, not a sofa bed. That might bother some, but in the end, it still works.I bought these sheets for my queen sofa bed because I had guests coming. They are a lovely color and according to the packaging they are made by Wamsutta and are supposed to be sateen 400 count sheets. I decided to wash them before use and even thought I set my timer to get them out of the dryer as soon as it stopped they came out horribly wrinkled and feeling more like a loofah than a soft sateen sheet. My other sateen sheets feel lovely and soft. I sent these back.The bottom sheet fits my memory foam queen sofa bed mattress perfectly, though I wish I could say the same about the top sheet. The top sheet only overhangs about 1" each side of the mattress before you even get into the bed, which is way too small. Not happy with this product given the price that I paid.Glad for the size. They are fine.Guests loved the feel and texture of the set. They fit perfectly on the sofa bed.The quality is less than I expected given the thread count but it's the only thing that fit the mattress on queen size hide-a-bed
