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.

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.

Don't buy these sheets! Sam's Club has changed the way they make the fitted sheet. The fitted sheet has this satin like material all along the sides. It's horrible! I bought these a few months back and hated them. I threw them away. It's been a few months so I revisited them, checked the reviews again. All these people make it sound like these sheets are so great. I thought “Awesome! They went back to the old sheets. Enough people complained” Nope, that's not the case. They are still horrible. Don't buy them. Plus they smell weird out of the box.

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 hate these sheets. I think the information is misleading. Hydrocotton and lycrocell not 100%cotton, but you dont actually see the lycrocell until farther down in the description. They feel like cheap dollar store sheet or those sheets that say 1000 thread count but never say what the threads are made from. I could have gotten these same sheets from a vendor on the side of the road for half the price.

I am so upset with myself; I purchased this last year but did not open until I changed the bedding over from winter to summer. Unfortunately, I had these for some time and did not realize that I had purchased the wrong sheets. The Members Mark 450 thread count solid sheet is a much better sheet than this one, I have only used these new sheets about two months and the seams are already starting to loosen and even though it is s 500 thread count the 450-thread count is a much better sheet and stays tighter on the bed. I won’t make this mistake again, for anyone looking for a great sheet and has a thick mattress the Members Mark 450 thread count sheets are the best.

I never received this product. It shows shipped with a tracking number, but no movement at all under the tracking number. I was looking forward to receiving these sheets, but alas, not this time. I contacted customer service several times via email and never received a reply to my inquiries.

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'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.

I love that the sheets are a bright white. They are soft to the touch And very comfortable. They fit the bed perfectly and the elastic holds tightly (Hate when the sheets come off When you’re sleeping). Not sure about the temperature control haven’t really noticed a difference, but wasn’t looking for that feature either. Great buy!
