These are super-smooth and they don't pill up like other cotton sheets (the organic cotton sheets sold here did pill within a few uses so I returned them and got these). They have an extra stretchy panel on the top and bottom to help keep them snug on the bed. I have an 8" high-end futon mattress and these fit just fine; I imagine they'd fit up to a 15" mattress. The colors I got (gray and teal) are nice, I just wish they had more options. I'd buy two or three more sets if they had other colors besides beige tones. I love these sheets so much! I'd recommend them to anyone who wants cool 100% cotton sheets that feel great and wear well. Trust me, I looked all over and couldn't find anything comparable at this price.

I love them, I purchased the orange colored sheets and they are absolutely rich looking and have a silky satin look, although they are 100% cotton! I use to but the 80.00 sheets from Sams Club for my king bed, but for the price of these, they are what I will be buying!

I bought my first set of the members mark 450 count sheets several months ago on sale when my sister recommended them. I have been waiting for them to go on sale again. I just purchased 3 more sets. The flexi-fit is great. It is an area at the top and bottom that stretches and helps to fit snugly over the mattress. No more struggling to pull the bottom sheet to fit the corners. It fits perfectly on my 12" mattress. I love these sheets!

I have decades of experience in purchasing sheets, these are a stand out! First purchase in store followed by a scramble to identify the label for a second on-line purchase because of the exceptional quality of the set. Deep pockets, no struggle for mattress fit and the feel of the fabric is superb!

Very nice sheets. Well made with elastic band all around as it should be. Great fit, comfortable and a slight sheen that makes it look so elegant!! Yrs, you can buy softer sheets but these are a great purchase!! Im particular about what i sleep on, so these are a fantastic find at this price ( got mine on sale!!). Very very pleased......wash n dry well......have purchased more!! Nuff said!!

This is not my first purchase of Member's Mark Deep Pocket Sheet Sets. I have had 2 other sets for over a year now. No complaints here. They wash up nicely and I like that they have an elastic panel at the foot and head so you don't have to guess where the head and foot are when you are putting the sheets on your bed. They stay on the bed and do not pop off either.

The quality of these sheets are amazing. We purchased at a great price and the only reason it got 4 out of 5 stars is, I was looking for cool sheets to sleep on, and they are not as cool as I like them. Definitely not hot or warm, just a tad bit lacking the coolness I was looking for.

This is the third set of these sheets, over many years, that I have had for my king size bed. Sam's club must be getting them from a different supplier. I ordered the white and they are more of a cream color, not bright white like the previous. They also are not as satiny smooth and "cool" feeling as the previous sets that I have owned.

I’ve purchased these sheets many times and have sent them to my sister and friends. But this latest version is fuzzy and rough. They are also very rough. I had to return them. Now I have no reason to have a Sam’s Club Membership since the sheets were the only reason for me to have one.

I love these sheets. I bought in 2 sizes and they fit the mattress perfectly. He ends are gusseted (gathered) for a perfect fit. I have deep mattresses and there is plenty of room, but due to the design, will work on smaller sizes to. The fabric is perfect. They are soft, but crisp.
