you can't tell from the listing photos but their "omni fit " is just them taking the sides of the sheet and swapping out the nicer cotton for a cheap polyester fabric. yes it stretches nicely but now you also have a seam that goes around the entire bed that will wear out. it's supposed to be a benefit but it's just a cost saving, lowering quality measure. returning and won't buy again!

These sheets do not stay on, they're not that soft, and they look bad. The cost cutting is awful, the material that goes around the sides of the mattress (not cotton) is noticeably different, easily damaged, and lets the sheets slip off the corners. It can't have saved that much money to substitute this small amount of fabric. The Member's Mark brand used to be reliable quality, but now that's not a guarantee and it's unfortunate.

These sheets are absolutely terrible. When we opened the plastic wrapper the sheets had a horrible odor to them. So we washed the sheets which corrected that problem but when we put them on the bed two of the stitched seams were split. I'll be taking them back ASAP.

I bought these same sheets last year and loved them. They changed the material of the fitted sheet and it feels like cheap plastic that is rough on the skin. Sams just continues to disappoint me, between no longer carrying items I used to buy to tanking quality.

The sheet set was purchased a year ago from the store. I was surprised when I noticed a huge tear in the sheet while sleeping on them. I really loved the look and feel of the sheets. I can't believe they don't hold up as long either the higher thread count.

I absolutely LOVE these sheets!!! I won't ever buy anything but Members Mark sheets. Great quality, wash and dry great. I love the elastic in the corners to keep the fitted sheet in place.. and I love that they come in a six piece set which include the extra 2 pillow cases. I highly recommend.. and I now have 3 sets and ordering more .

I didn't notice on the listing or other reviews that the fitted sheet had a different material for the elastic surround. I was pretty surprised to see that it's a cheap polyester material, and then it still doesn't stay put on our mattress very well so there's a visible line between cheap polyester and regular sheets. The sheets themselves are a nice material, wash well and feel crisp ---- but I wouldn't buy again due to the cheap material around the edges of the fitted sheet.

I just bought these for my guest room and have never in my life seen such a cheap way to cut corners! 100% Polyester on the sides of the fitted sheet! Really!? It said 500 thread count on the packaging in big letters, but I never suspected that I would have to read the fine print to see that the fitted sheet was made with slippery polyester sides. Do better! Now I am stuck with these sheets because I washed them and my guests will be here in an hour. Ugh. Unbelievable. I feel cheated.

The sides of the fitted sheet are made of windbreaker-type material. Makes them appear very cheap and the worst is that these sheets are LOUD. Every time you move or turn over they make a loud swishing sound. I can't recommend these, I only wish I could return them but they e already been washed.

I'm giving these 5 stars based solely on quality and workmanship. The stitching is excellent and the material is a really good cotton blend. They do feel, in weight and quality like a 700 thread count cotton sheet. I ordered one print and one solid set and they were both beautiful and looked vibrant. I have slept on the printed sheet set for a week now and they are equal in every way to cotton in comfort and breathability. My wife sleeps hot and she loves them. I gave these a shot based on the incredible price, for a fitted king sheet set it was cheap to say the least. I figured it's Sam's club the return will be hassle free if I don't like them. All that being said these are not perfect. I read about the supper annoying dye smell and it's absolutely true. They come extremely well packaged and as soon as you open them you will be overwhelmed by the fun odor of what I can only describe as hot, wet, card board. Even though I read about this I was unprepared for the smell. Fortunately, I was prepared to launder them so I didn't have to suffer long. I washed these in cold (Tide) and tumble dried them on gentle and I don't know if it was still some smell lingering in my laundry room (I had to wash each set individually as they are different colors) but there was a ever so slight hint left so I washed them again in cold (Tide) and dried them again on gentle with my usual dryer sheet and after removing them promptly they came out perfect. As mentioned before we have slept on them for a week and they smell and feel like putting on fresh pj's as a kid. I like them so much I just bought another set in a different color. So if you don't launder your bedding before you use it you are gross and so are these. Sorry, just saying.
