I don't think these are cotton. I have egyptian cotton sheets of various TC and sateen as well and NONE are slick and drapey like these. Sateen has a matte sheen to them, but these are close to a satin fabric. They feel like they'll be hot and I feel a hot flash coming on just touching them. I'm returning these. If they ever lose the slick feeling I'LL never know because I'm not going to wash them repeatedly and risk not being able to return them. Also, they have a funky smell. They smell like they were kept in someplace damp. I know I can find real cotton for this price and not this rayon feeling nonsense. I HATE EVERYTHING EXCEPT THE COLOR AND 2 EXTRA PILLOWCASES.

I wasn't sure I would like these sheets. I usually sleep on bamboo sheets. I washed them five times before I put them on the bed the first time. very happily surprised with them. they are thicker than bamboo, but not too heavy, they are nice and smooth. With each wash they do get better. I think they are well constructed. I'm also very happy because I got them on sale.

The Member's Mark Premier 700 Thread Count Sheets are SUPER SOFT. Every other Sheet set we have every tried for our bed (even the elasticized ones 'guaranteed' to fit)...never did. WE have found our perfect Sheets! We love that they are Elasticized ALL the way AROUND...so they fit...and they don't come off. We have two Twin Extra Long Mattresses on a KING SIZE frame...for our Adjustable Bed. It allows each of us to put our Mattress at the level we want. Most Sheet sets for king size are too small for this type of set up...but not the Member's Mark Hotel Premier Collection...and sooooo soft. Thank you. Thank you.

These are really great sheets. The elastic is around the entire perimeter of the bottom sheet which means it never slips off. It's also a substantial elastic which was pleasantly surprising. Nice material. Yes, they did come out somewhat wrinkled on the first washing as some members complained about. But we don't mind it. Once they're on the bed it's not noticeable. We had such a problem with our other, more expensive sheets, not staying on the bottom mattress that we are thrilled with these. We're going to buy a third set.

I really like these sheets but had to take off a star for the smell. They reeked when I got them. Like they'd been stored at a manure farm. I mean really smelly. One wash took care of it, though and now they're fine. I like the deep fitted sheet for our king mattress- they fit well on our Sleep Number.

Bought my first set of these sheets two years ago in the Club. Still have that set, and it's as soft and comfortable as it was then. Now own five sets just in case they become unavailable in the future, or Sam's changes the supplier and the product suffers ... which, let's face it ... happens. I just turned 69 and I want these to be my "forever" sheets. lol

Great sheets. Nice and soft. They seem durable as well. I have only washed them once though. I bought these on sale. I'm not impressed by thread count so much as softness and durability. I bought this brand of sheets when they were 500 tc, and these seem to be the same.

I bought these Feb 10th and they ripped. My wife sewed them and they ripped again. She only washed them like 2 or 3 times. Horrible material. Will be returning the set i didn't open. I bought 2 sets. Will buy Mike Lindell's bed sheets. Never will i ever buy this crap again!!!

These sheets used to be the best, along with the same ones just with stripes; however, the last three sets I have purchased they get tiny holes in them after the first wash. Tiny holes eventually turn into big holes, these sheets don’t last me six months. I wash them once a week. I have bought other sheets I use and wash them the same, and the do not get tiny holes that turn into big holes in them. For the price, you will be better off getting them somewhere else. There’s no excuse for these sheets to do this.

Don't be like me - believe all of the bad reviews on this one. I ordered these online. These sheets smelled horrible (like ripe butt bad). Since they felt great to the touch like other high thread-count sheets I've purchased before, I decided to give them a chance. I washed them twice according to the instructions, and they smell a little less bad but are now very scratchy and unusable. After decades of bedsheet purchases (cheap and expensive), I've never had bedsheets that changed in texture so drastically after gentle washing, and I've never purchased sheets with such a terrible smell. These are being returned.
