Listen, if your house is currently functioning like a high-traffic terminal at LAX with kids, pets, and everyone treating your bed like a communal lounge, you need these sheets. I’m at that fun stage of life where my internal thermostat is basically a broken toaster thanks to perimenopause, and these Member's Mark Cotton-Lyocell ones are a total sanity-saver. I’m talking about those 3 AM "human torch" moments where you’re ready to sleep in the freezer—these actually stay cool. The lyocell blend is like having the cool side of the pillow wrapped around your entire body, which is a miracle when you’ve got a seven-year-old and a dog pinned against you. I went with the navy blue, and I was honestly a little nervous about waking up looking like a Smurf or having my mattress ruined, but they didn't bleed or transfer at all. They stayed perfectly dark and kept the dye to themselves. The best part is the Flexifit corners because, let’s be real, between the kids doing wrestling moves and the pets nesting, most sheets end up bunched in the middle of the mattress by midnight. These actually stay put. Plus, it’s a six-piece set, so you get four pillowcases, which is essential because in my house, pillowcases are apparently communal property. They come out of the dryer looking surprisingly decent, too. I don’t have the time or the soul left to iron bedding, so the fact that they aren’t a crumpled mess is a huge win. Honestly, if you’re trying to survive hot flashes and a house full of tiny, loud roommates, just grab these and thank me later.

My last couple sets of sheets were micro fiber bamboo or something. These sheets are drastically different and I’m loving them. They are crisp and soft at the same time. Very deep pockets, 2 bands of gathered elastic at the fitted corners. And if you can believe it, there are tags at the center of each side that specify if it’s a top/bottom or a side. That’s just darn helpful information!

The members mark performance sheet set just outdid itself. We always loved the members mark hotel collection, but this new set is even better. It comes with a fitted sheet, a flat sheet, and 4 good sized pillow covers. First off, they are very soft, and the sheets kept cool all night. The pockets are very deep, and fit our large mattress with ease. Instead of a solid sheet, the sides are stitched on all around giving it a sleeker look. There is elastic all around the bottom to hold in place, and also extra elastic on the corners a few inches up to keep it extra snug. I though the storage bag would be nice, but it’s so small, you can really use it again, unless you can somehow cram the whole set it. We will just use a pillow case like always to keep the set together when not in use.

This is a nice sheet set for the price. I like the color options available and am very pleased with the soft green I received. I don't feel overly hot sleeping with these sheets, so they definitely seem to be temperature-regulating as advertised. My mattress is very thick and also as advertised, the fitted sheet has deep pockets and stays put on my bed. My one negative characteristic is that they aren't very wrinkle resistant but I also didn't put them on my bed immediately after drying so I guess that's to be expected! I would buy another set if I needed new sheets.

I have no idea why they changed this sheet set.....it use to be great and I would only buy these sheets......now I will not recommend nor will I ever buy then again.

Flimsy material. Sides of the fitted sheets are some sort of synthetic material. Disappointing. I needed full bed size sheets, and this was my only option.

The sides of the fitted sheet are a noticeable different shade. They also don't fit well and they don't have the same comfortable feel as cotton sheets. I honestly didn't notice they weren't 100% cotton and kept them because there's no way to get them back in the package.

Package said full size sheet set. It was purchased as Christmas gift. We opened & washed before we gave them as gift two weeks later. Because who wants to sleep on new out of package sheets. Went to put on the full size bed & did not fit at all. A foot, at least too narrow. They were twin size in a package marked full.

Cheap ! Used to like these sheet, but they have cut corners and using a cheap material on the fitted sheet. Not sure why they just didn’t go ahead and use regular sheet material. Corner came unraveled after 2 nd washing. Do not recommend wasting your money on them.

Sheets wash and clean up well, but if you have pets, they also easily tear. This is the second set i've purchased from sam's and they've both done the same. Have other sets of sheets 5+ years old from walmart and other sources never had a problem? Not sure why only with sheets from Sam's?
