    Like many folks, I've always been a student of the 400+ thread-count school. Boy, was I wrong. I've been testing out the Signature queen sheets for about a month now and I'm placing an order for our king bed. They wash beautifully and feel amazing. I'm so happy to say that I'm supporting an honest MADE IN THE USA product! Obviously these folks know what they are doing and I can't recommend them enough. You've not had a real night's sleep until you try Authenticity 50! I'll never buy anything else.

    Happy Signature Customer

    I’m pleasantly pleased with the quality and fit of the queen size sheets I purchased online. They fit over the mattress perfectly without feeling excessively tight or stressed at the corners. They’re still new and very comfortable. I’m confident they will get even softer with use and washings. This was the first time I purchased sheets online without physically inspecting them before buying. I’m even happier that I didn’t have to drive to a store and waste time shopping around. I recommend Signature Sheets without any hesitation or reservation.

    Best Sheets

    I received my first set of these sheets a little over a year ago as a present. When I first received them, I wasn’t sure about them...until I put them on my bed. They’re so comfortable, and they keep a good temperature; never too hot, never too cold. I love the pillow cases because of the closure. My pillows used to always fall out of regular cases, and now they don’t. The most important thing, in my opinion, is that this company grows and makes the sheets in the United States. It is important to my family and I, to purchase as many items that we can that not have toxic chemicals and other mysterious components. We also feel great supporting a company that creates jobs in the US. I can’t wait for new colors and hopefully will see some additional cotton items in the future!
