This is a very difficult review to write. Delivery was super fast, and When I got my sheets I washed them in cold water, and line dried them as I do all my sheets. They fit my mattress perfect, I even had extra room, which is hard to come by these days when you have a thick mattress. They were very comfortable, probably more comfortable than any other sheet I have purchased in the past few years. I alternate between linen, and percale, (high end bedding). However, after having them on my bed only six days, I went to make my bed and straighten out my fitted sheet, and I heard a rip; the corner had come apart, frayed. I was so shocked. I don’t know if I received a defective sheet, but I am returning it obviously. I am still undecided on doing an exchange, or if I should just get a refund. My last 2 sets from another company, I have had for 2 years, and still has held up well, and I even have cheap sheets that I use sometimes in between, and they never ripped. I take good care of my stuff. I even use high-quality laundry detergent, I use the laundress detergent, and regardless, it should not have come apart that soon. I will say that they are very very comfortable to sleep on, but the stitching is not that great for a sheet that cost $130. I compared the stitching to my other sheets, this sheet doesn’t have tight stitching, the threading seems loose. However, it could be that my sheet was defective. If it weren’t for this issue, I would give a 5 plus star rating for the comfort, and the sizing, as they feel wonderful to sleep on.
