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 this set on sale to replace a set that had worn out the fitted sheet. I noticed that the new fitted sheet was different than most fitted sheets. Other reviewers didn't like this style but I think that the design helps the sheet stay on the mattress better. The fitted sheet has a seam that lines up with the top of the mattress. then the sides are sewn on. The corners have two sets of elastic - one at the bottom as normal and another set of elastic around the middle of the corner. So far, I like it. The material is smooth, maybe not as comfortable as some material, but for the price I think it is great. And my favorite part - the set comes with FOUR pillowcases. I sleep with extra pillows so I think this feature is awesome. Overall, I would recommend this set.

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!

Disappointing Quality – Not Worth the Money These sheets were a huge letdown. The so-called "side stretch technology" is just cheap, flimsy polyester that feels weak and tears easily. After just one wash, the cotton top portion started separating from the stretchy sides. The stitching and material quality are clearly subpar. I expected better durability and design, especially at this price point. Total waste of money. They need to bring back the 450 TC 100% cotton sheets

I noticed some comments about an unpleasant smell when opening these sheets, so I decided to test them myself. Yes, there was a faint smell when I first opened the packaging, but after washing them one time in normal detergent, the smell completely disappeared, and I love the fit and feel of these sheets.

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.

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.

Pillowcases ripped on first wash. Returned!

Amazing quality, cool, strong corners. These sheets are the best

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