These are cotton, and synthetic blend now. I've purchased the sheets for over 12 years. I got one set not realizing they've changed. They pill up, and we literally wore a huge hole through them in a couple months. The sheets totally shredded. I went back to sams to look at the sheets again, and the are pilled up on the outside from people touching them..really cruddy quality.

I purchased these sheets and thought they were the same as I bought almost a year ago. WRONG, BUYER BEWARE. They are horrible and nothing like they used to be. I did check all the reviews however with so many 5 stars I thought well I will give them a try. I washed them went to put them on the bed and the seem on the bottom sheet tore open about 4 inches. Never used and first time washed. I hate this because I loved the ones I bought last year. I actually don't get the higher raitings. Go back what you used to sell and you have a winner. I actaully rarely give reviews good or bad but this time I had to tell it like it was. DONT'T BUY. So frustrated to say the least.

I ordered these sheets, and on initial evaluation they look and feel great. HOWEVER, they arrived smelling like very strong dog poop or a dead animal for some reason and stunk up my whole house. It look washing them twice on heavy duty cycles to get the smell out of them and I think it is still lingering in my living room where I opened the package. Very frustrating. I was gagging just trying to get the cardboard pieces out of them before putting them in the washer.

I am so happy with my purchase of the Sam's Club 500TC Performance Sheet Set! The sheets are incredibly soft, smooth, and comfortable. They feel luxurious, but without the high price tag. After washing, they stay soft and don’t lose their shape or color.

I have been buying these sheets for a very long time. I haven't bought any lately because I buy 4 at a time. I have had these for ever because they last a long time. The reviews lately scared me because they say they stink and material is cheap. However I was very happy to see this wasn't true. The sheets have a beautiful sheen to them and look very expensive. They feel so soft and do not wrinkle. They do have different material on the ends but they look good and you don't lay on that part. I love the deep pockets and the thick elastic I bought 6 sets and love them. Also they come with 4 pillow cases and they are longer than the normal ones. I love that because my pillows are queen size.

Horrible sheets. They are not 100% cotton. They do not breathe and are itchy. They retain heat. Extreme wrinkled (fitted sheet). The corners are strange with extra material. The fitted sheet is so thin that it is almost see thru. Definitely not worth the money. I wouldn’t take them even if they were giving them away.

I bought these and threw them in the washer and dryer. And the pillowcase was missing sewing on the side seam. So there's a hole in one. I'm glad that there are 4 pillowcases. They are for deep mattresses, they don't adjust well for regular depth, the are quite saggy.

Would be higher maybe Sam’s Club kept sending me the wrong sheets three times.

So disappointed in these sheets. Your original MM sheets were amazing.

Top part of fitted sheet is fine. Sides of sheet are pilling up a lot and easily “ scar” up.
