    Our search has ended!

    We were looking for GOOD sheets. The last set we purchased from a big retailer, pilled and wore thin in the feet area....after one year! So I read and read about sheets, and reviewed many products. We finally decided to purchase a set of Authenticity 50 sheets. We received the sheets and did as the instructions said... washed in cool water, dried on low. They fit great on the bed...first night of sleep? Sheer BLISS ! Comfortable, crisp yet soft...and the envelope pillow case? We love our pillows being contained and not falling out of the case. The first thing my husband said when we got up....go order another gray. Don't change your product...we do not mind the wrinkles...we love the comfort and we love the made in America...thank you so much!

    One big problem ...

    I could go on and on about how amazing these sheets are. Yes, they fit the bed like a glove and there is enough material in the flat sheet to tuck under the mattress and it won’t budge. Yes, these sheets have amazing temperature control. Yes, the envelope pillowcase enclosure is perfect. Yes, my difficult to please cats even enjoy sleeping on these sheets. There’s one huge flaw in these sheets though .... I never want to leave them. They just present a fairly large “life” problem I hadn’t initially anticipated. Anyways, I think it’s pretty safe to say I’ll be a repeat customer.

    Hi Julie, We love that you're sleeping better than ever! Hopefully you solve your "life" problem of never wanting to get out of bed.. sounds like quite the dilemma! And we can't get enough of your cat in bed - looks like she's as happy as you are! :)

    My favorite!

    My husband and I love these sheets. They fit our very thick king size mattress perfectly. No more pulling and pulling to get sheets to fit only to have to fix them every morning. These sheets are soft and keep you cool at night. They are very well made. I absolutely love the pocket pillow cases, genius! I will definitely be ordering more of these sheets and I highly highly recommend! LOVE MADE IN THE USA!!! Wondering if they will come out with flannel/fleece sheets in the future?

    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.


    Fitted sheet not deep enough for P5 Sleep Number

    We got king set in grey with duvet cover and flat sheet (I am trying to avoid washing duvet cover weekly). Sheets are comfortable, breathable and soft. I wouldn't call them crisp. My biggest issue is the fact that fitted sheet is not deep enough for my P5 Sleep Number mattress. My mattress is about 10 inches tall. Doesn't look good on platform bed. Unfortunately my cheap sheets had much better fit. Just outside of the 100 day trial window so I am stuck with this irritating drawback until they wear out. It's my fault for procrastinating. Would not buy another set because of this. Not at this price point.

    Dear Lyasya, We're sorry to hear about the issue with the fitted sheet not fitting your 10" mattress. That certainly shouldn't be the case! Can you please reach out to us at with a picture of your issue and we'll get you taken care of right away. Thank you for supporting Authenticity 50 and our Made in USA bed sheets!
