I have the Member's Mark, performance, 6 piece, king size, cotten-lyocell sheets and pillowcase set, 500 thread count. It includes 1 flat sheet, 1 fitted sheet, and 4 pillowcases. I have to say, they are honestly the best sheet and pillowcase set I've ever owned! This is my first 500 thread count sheet and pillowcase set and they feel luxurious to me! They arrived perfectly packed and quality of material was flawless, The highlights on this sheet and pillowcase set state to be, moisture wicken, temperature regulating, wrinkle resistant, with a FLEXFIT deep fitted sheet that fits mattresses up to 17". Im here to say that they have proven to be all of that! Plus, I was surprised on how heavyweighted they are! With this sheet set, I sleep extremely comfortable neither too hot or too cold, We have a queen size pillow top mattress, however, I always put king sheets on it due to the pillow top on my matress, most all queen sheets are too small, so I can't matter-of-factly comment of the fit of this set on a king mattress set unfortunately but, I have no doubt that the fit would be perfect on the correct size matress for you, I am very happy with the extra fit of these sheets for me. My absolute favorite surprise about the fitted sheet was that there are tags sewed on indicating top/bottom and sides! Now this my sound ridiculous for some of you to read this but, I am that person who STUGGLES to put on a fitted sheet so this little detail made making the bed a pleasure and not dreaded anymore! I am pleasantly surprised by this sheet and pillowcase set, The best way I can describe these sheets and pillowcase set is that they are durable, weighty, soft, and perfect to sleep on. I can see this sheet set lasting a very long time! If your looking for a new sheet set, I think you too will be pleasantly surprised by the quality of this set!

These sheets are fantastic. Right out of the package they felt soft, but after washing them once they got even better. The fabric is smooth, breathable, and doesn't trap heat, which is a huge win if you tend to sleep warm. The king size fit is spot on—no fighting with the corners or waking up to sheets popping off overnight. They've held their shape and color really well after multiple washes with no pilling or fading. The elastic around the fitted sheet is strong and keeps everything in place. Overall, these feel like high-end hotel sheets at a much better price. I'd absolutely buy them.

I received the Members Mark performance 500 thread count sheets, 6 piece set. After washing the sheets they were a little wrinkled but with time they straightened out. The sheets are of good quality and very soft. The queen size I got is generous in size, its nice to not have to struggle when making the bed, especially when putting on the fitted sheet. Thank you Members Mark for a Great nights sleep!

These sheets are silky smooth comfortable to sleep on. The fitted sheet was deep so we didn't have to worry about the sheets curling up on the corner. They kept us cool at night which is a plus due to night sweats. We would definitely get more of these the set comes with the fit, flat sheets and pillow cases and we loved the color.

I changed the color scheme in my bedroom and on a whim, decided to add sheets to that as well. I was at Sam’s, saw these and I’m so glad I picked them up! Washed them, threw them in the dryer and when I took them out, there wasn’t a single wrinkle in them. The pockets are nice and deep and the fit is perfect on my mattress. The feel is very high quality and comfortably soft.

I have been rather pleased with the sheets I have bought from Sam’s Club over the last 15+ years. I gave my adult son a set as a Christmas gift a couple of years ago and made a convert. These sheets are crisp and thick. They are not too hot we use them year round in the deep south. They wash well and will last a long time.

These are great sheets. My favorite part about them is the nice deep pockets on the fitted sheet. I often have issues with sheets coming off the mattress and these seem like they will stay on, even with a thick memory foam mattress! The material is comfortable and not too hot or cold at night. Overall, I am pleased with these sheets

The material on these are fairly thick and feel very durable, but they are still not too hot and suffocating. I really like that the label the top and side with tags. The material isn't exactly soft, but it doesn't feel coarse either. I would describe it more as smooth due to the thickness.

These sheets are great quality. The material is nice and smooth, not cheap or itchy feeling. It has a tag inside to let you know which is the top or bottom so no fuss trying to figure out which way the sheets go! The color is as expected- a light grey and matches everything.

I had to return these sheets because they had a very very strong chemical smell right from the package. It was so bad that you could smell it even when they were still in the shipping box. Not sure what they are using to manufacture these but I've never had sheets smell like this right out of the package before.
