    I already had the duvet cover set with fitted bottom sheet and pillow cases and decided to add the top sheet and additional cases for warm weather when a duvet is not needed. These pieces color match perfectly!


    Love the sheets!

    I researched and researched before buying the A50 sheets. I really wanted a Made in America product and was really pleased to find all the information on the website about sourcing, manufacturing...all of it. We love to support small businesses, too, so that was another plus. I also really wanted to be able to get a queen fitted and king flat sheet. I just like an extra big top sheet, and not all companies have that option. We've just had the sheets for a couple weeks now, but they have not disappointed. The weight is very comfortable...not too light and not too heavy, and the cotton weave is great. I'm so happy we treated ourselves to this quality product, and I know we'll be enjoying them for a long time! Thank you!

    Perfect sheets

    Perfect!!! The best part is that they are entirely made in the U.S.A. The sheets are so comfortable and we have never been so comfortable in our bed. Congratulations. It makes me laugh when the ads say their sheets are the greatest. All are made in foreign countries. Thank you for sheets made in America. I have recommended your sheets to several people.

    Thanks for the Flat Sheets!

    I needed to have an extra-long queen flat sheet, so I was able to purchase an additional flat sheet now that you sell them individually. Thank you so much! I stitched the additional piece of fabric onto the end of the flat sheet I already had purchased, and now my newly lengthened sheet fits my needs perfectly. Thanks for being sensitive to your customers needs. Perfect sheets, perfect company!!!

    Loved the first set sooo much, bought a 2nd set!

    Title says it all. We loved the first set of sheets so much, we bought a 2nd set. Authenticity also helped us out by making available a king size top sheet only for purchase. Thank you Authenticity!

    Love the sheets and duvet. Really, really love the customer service!'

    After receiving my first order of duvet, sheet and pillowcases, I wanted an extra top sheet. It was sent immediately and I really appreciate the quick and courteous response. Will use their bedding exclusively!!!! So soft and welcoming after a long day! A-plus for being made in USA!! JD Tucson
