The fitted sheet has a top panel that is cotton and the other portions and side pieces are polyester. So the entire sheet is not cotton. Otherwise the cotton feels nice.

The elastic is not tight enough and the fitted sheet slides down the mattress. We need to pull it back up every morning. The sheet material is very soft and comfortable.

I hesitated to buy these as I generally buy the higher quality sheets - but wow- very nice - little wrinkle and as smooth as the Egyptian cotton types

These smelled funny when removed from package. Required washing before using. Tiny elastic around fitted sheet. Coarse feel. Wrinkly. Previous purchases were nice. Won't buy them from you again. Terribly disappointed.

The sheets are so soft. I need to have a clean set of sheets when I come home after my knee replacement surgery. So I had a set already. So I bought these as my second set.

Washed and dried sheets, by themselves, and the fitted sheet had a hole in the corner seam when removed from dryer. I've had good luck with Sam's sheets in the past so maybe it was just a bad set.

Very good quality sheets, HOWEVER, if the twin pillow cases are considered 'standard' then I can't imagine what the king covers look like. These 'standard' cases are enormous. Way too big for a standard / twin pillow. Thankfully I have other beds that use larger cases otherwise these sheets would be going back.

The fitted drop panel is 100% polyester....cheap! 65% cotton 35% lyocell They do not smell good coming out of the package. The packaging says you're supporting Sam's Club investment in Better Cotton's mission. Below in small print: This product is sourced via a system of mass balance and therefore may not contain Better Cotton.

These sheets are extremely poor quality. Every night before bed the sheets need realigned with the mattress. They do not stay in place and give a baggy sensation once in bed. Also, they have a horrendous smell that doesn't come out even after washing. Don't waste your time or money with these sheets!

Would Not Recommend. The fitted sheet has sides that are nylon-like material, not cotton. The elastic allows the sheet to become so loose that the material becomes excessive on the bed. Does not stay at all tight. The 500 thread count feels cheaper than my 400 thread count sheets. I would not recommend paying this much for these inferior sheets.
