I purchased these sheets in the past through Bed Bath & Beyond, and was very pleased with their quality. I was dismayed when BB&B stopped carrying the brand. I tried others, but finding a quality twin xl sheet set like Wamsutta never happened. I was so happy to hear that they started manufacturing again. I was a bit apprehensive because another company had acquired the brand. I decided to order a set because of their return policy. I was very impressed not only with the delivery and packaging but the quality of the sheets. So far, after 3 washings, the sheets have held up and have not shrunk. I followed the instructions, cold water and low heat. I do have a 2" foam mattress topper, and the bottom sheet does not come off. So far very pleased with this purchase.
