I really wanted to give these sheets a 5 star but couldn’t. First I want to say they are very comfortable. They are a cotton knit much like a t-shirt not like the shiny ones in the photo. The color I got was a Robin egg blue instead of a dark blue, which is fine as I prefer the lighter one, But they aren’t as pictured. Also on the plus side they fit the beds well. We bought a split king sleep number and we found the down side is the mattresses slide apart causing a hole. We tried several things and the beds still slid. We decided to try sheets made for a split top. They worked well to keep the beds together. You can still see a little indent between them at the bottom but not like it was before. Another nice feature, because they are a knit, the bottom of the bed on one side can be raised some without hurting the sheets. All in all we really like the sheets. The reason for the 3 star is I dont know how long they are going to last. I washed them before use and the photo shows you how much lint came off the sheets. That is a 4” x 4-1/2 “ x 1-1/2” pile of lint. I just washed them again after use and got another pile of lint just as big. They were washed On the color cycle and on delicate drying. If this continues I wonder how many uses we will get before they aren’t comfortable, have holes, or threadbare in spots. I can’t afford to keep buying $80 sheets every few months.Great set. I was not sure if I should buy them, however the price is good so I had to try it. Great quality can't tell the difference from the one I bought at the company, which by the way it was sooooo expensive. I made sure that I placed the split someone loose because I do not want it to rip as others had said. The fitted has enough space to place it perfectly. i had washed them already so far so good. I am buying it again and would recommended to others.UP DATE: 7 MONTHS LATER IT DID RIP IN THE SLIPT PART OF THE BED. I GUESS YOU GET WHAT YOU PAY FOR.I have been pleasantly surprised by the quality of these sheets for my king Sleep Number split-top bed. The fabric appears to be comparable to the Sleep Number sheets we have and they fit very well on the split top mattress. One feature I particularly like is the elastic around the corners without a loop (there's elastic all around the edges also). The Sleep Number sheets have an elastic loop on the corners (in addition to elastic on the edges) that makes them difficult to place on the split-top corners. These sheets are much easier to put on the bed and about half the price of the Sleep Number sheets.These are very nice, good quality, wash well, and the fit is great. If I have one complaint, it would be some pilling after a few washes. However, these are a much better product than the sheets sold by Select Comfort, and at a fraction of the price!Just received these sheets and put them to try the fit. $100 doesn’t go as far as it used to. The sheets seem to be less than 300 thread count and are thin. The fitted sheet is very large compared to other sheet brands. Kinda feel guilty for only giving 3 stars so I will update if they hold up well over the next year.Ordered a set of split to king sheets. The fitted sheet did not fit my bed. I contacted the seller and they immediately sent a perfect replacement.Great experience!!These fit very well and even though not the highest quality or thickness they are comfortable. It’s sad that they cost so much just being split top sheets.Had some issues with the sheets initially, customer service contacted me and took care of the problem promptly. Sheets are comfortable and the customer service was great.
