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 do jot recommend these at all! These sheets are poorly made with a seam going around the perimeter of the fitted sheet. After only using for a couple months the sheets are ripping at the seams, and they are not a right fit on our bed. Theyre actually really too loose. We don't solely use these sheets as we switch out with other Members mark hotel line sheets (which we love!) so they haven't been getting used and washed enough to warrant falling apart this quickly. I had an ill feeling about these sheets when i opened the pakaged and saw the drop panels on the fitted sheet were sewn on and a different material than the rest of the fitted sheet. I would not recommend this specific line of Members mark sheet sets!

I was initially a little disappointed with the polyester sides on the fitted sheet but after having used them I don't think it matters as much. They aren't as soft as I'd like but i think I'm just spoiled because I had purchased the 700 TC members mark set last month and it's amazing. But I've heard this set gets softer with every rewash so there's still hope!

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.

These were great sheets, but they change the fitted sheet. It now has this satin panel around the edge of the mattress. I think it was added to fit a deep mattress better. Well, it fits too well. Now the satin edge rolls up to the top of the mattress, and I end up laying on it. I feel the two different fabrics under me, and I don't like it. It also does not stay on the mattress as well either. The other sheet are the same as before and are great, but this does not make up for the poorly designed fitted sheet to make me get these sheets again.

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've purchased Welspun at another retailer a couple of years ago. They were called their Welhome Performance Cotton, being a cotton/polyester blend. I absolutely love them. The tailoring is top notch and the fabric is comfy and wrinkle-free. The retailer stopped carrying them so I sought other retailers. The big online retailer, Am****, shows them but none are in stock. I mean zero! I then emailed Welhome… no response. I called their phone number… disconnected. I even emailed their headquarters in India… no response. I was excited to finally see Welspun at Sams but was nervous with the fabric being a lyocell/cotton blend but I bought two queen sets. I washed one set before putting on our bed and was immediately disappointed. The fabric was horribly wrinkled and was embarrassing to have on our bed. There's no way I'm using these in our guest room. I'm returning the second set that's still unopened. Sams, please get the poly/cotton sheets. They're far better. Welsun, you're a horrible company with NO customer service or genuine concern. Sell your company to someone who cares about customers it has and those it could have.

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

these sheets smell like cat pee need to wash. Then i will know if i like them.

Pillowcases ripped on first wash. Returned!
