Soft cotton flat sheets

Do you remember the high-quality, American-made bed sheets from 20-30 years ago. We drew inspiration for our Signature Sheets from the old Fieldcrest, Cannon and Springs sheets of our recent past. Those sheets were made to sleep cool, get better with washes and stand the test of time.

Discussing with expert manufacturers we settled on 100% American-grown cotton as the foundation. Cotton sleeps cooler in the summer and warmer in the winter to help regulate body heat. The experts also advised a thread-count in the 200-250 range as giving the best durability and softness - we settled on an honest 220 for a crisp feel that keeps you cool in the summer and will last for years.

And if you hate having your pillow falling out in the middle of the night you’ll love our Envelope Closure Pillowcases. They keep your pillows tucked in their case, right where they should be.

Frequently Asked Questions

From laugh lines to broken-in blue jeans, wrinkles tell a story of a life well lived. We minimize chemical wrinkle treatments for better breathability, durability, and a softer hand. Anti-wrinkle treatments use harsh chemical resins that reduce the quality of the fabric and are potentially bad for your health. We chose a great night's sleep over wrinkle-free chemicals.

We've all heard that higher thread-count is better. But that's simply not the case! For soft, cool sheets that hold up for years, 180-280 thread count is a perfect range. Transparency is important to us which is why we offer an Honest 220 thread-count sheet set.

We take care of our customers and offer free shipping for orders to the lower 48 states, as well as Hawaii, Alaska, and APO. Orders are typically shipped within 1 business day, and most orders are delivered in 2 business days.

  • Wash on cool, gentle cycle.
  • Tumble dry low on low heat.

Kristin R.

I love the sheets and also that you can single sheets in case you need just a top or bottom sheet. Thank you for your quality as well.

Jason W.
These are really GREAT SHEETS. Thank You!

The Title of Review says it all, but to break it down: Made In USA. Perfect ft. Perfect feel. Perfect.

James S.
Best sheets ever

I’ll never use another brand. Soft and comfortable

Carly S.
Very Nice -

Overall I like this sheet - it is breathable and the fabric seems like it will age well. Some of the seams were a little cheaper looking than I expected given the price point - but overall I like to try to support companies that are paying a living wage to their employees. I don’t have a lot of money but I try to buy less items that are better quality and are good for people and/or the environment. Hoping that these sheets meet the quality standard to last for many years.
Also, I wanted to buy a whole set but they are NEVER all in stock. I know that the supply/covid etc…. but it is still a bit annoying. Would be nice if they offered 1 warm colour (like ivory/cream/warm tan).

Best Sleep in the USA !

We love our sheets they are so nice and cooling for me and my husband likes the warming. They fit our California King like a glove easy to make the bed with just a pull to straighten out sheets. Then on with my day!

Made in USA from Seed-to-Stitch®

Our goal with every product is to make something YOU WILL be proud to own. That’s why we focused on making sure our bed sheets are 100% made in the USA, every step of the way. We were told it was impossible to make bedding in America, but we didn’t listen. You’ll be proud to be in the 1% of Americans who sleep on American-made bedding.

Our Signature Sheet Sets start with American-grown cotton. That cotton then takes a short trip to Georgia, where it will be spun into fine yarns and woven into sheeting fabric. Both the spinning and weaving process require highly skilled technicians and specialized machinery to make sure the fabric meets high standards of durability and quality. After weaving, the fabric is finished in Tennessee, and then finally cut & sewn by hand into the sheets you love in New Jersey. You’ll love sleeping on these bed sheets made in America from Seed-to-Stitch®.
