Wicks Away Moisture

Care

Durable Zips, Easy Cleans

FAQ
Questions, answered honestly.
How do SHEEX sheets actually cool you down?

Our performance knit pulls moisture from your skin and disperses it across a larger surface area, allowing heat to evaporate faster than traditional cotton. The result: a consistently cool sleep surface.

What's the 60-night guarantee?

Sleep on your SHEEX for 60 nights. If they aren't the most comfortable sheets you've ever owned, we'll refund every dollar, no questions asked.

How do they hold up after washing?

Unlike cotton that softens then breaks down, our performance fibers retain their softness and shape for years. Machine wash cold, tumble dry low.

Will they fit a deep mattress?

Yes. Our fitted sheets stretch comfortably over mattresses up to 18 inches deep, including hybrid and pillow-top constructions.

What's the difference between the SHEEX collections?

Each SHEEX sheet set has a slightly different feel and is designed to address different sleep needs. View our comparison chart to find the best sheet set for you.

Reviews

This should be a 1 Star Review

"This should be a 1 star review but hear me out these Sheets, Comforter, down pillows, and mattress pad combo are TOO good. I got a bundle deal of the original performance sheets, the mattress pad, comforter and duvet cover, and added the down pillows as a bonus and I have now been late to work TWICE because of the absolute euphoric cloud these product create to sleep on. I would give it a 1 star review for almost making me lose my job but it would be a disservice to how absolutely magical these sheets/ extra’s have been. Be wary if you sleep in these you will enjoy them…. TOO much."

— Nathan B. (5/5)

Im not filling out this ridiculous review

"I stayed in a hotel/ motel maybe 13 or 15 years ago in Ocala. They had the most comfortable pillows I had ever slept on. I looked at the label and bought some. They became worn out so I bought some more. The product is great. If you want to do something to improve work on communication. The day I received an email informing me the pillows had shipped was the same day I received the order. For a week I was wondering when you were going to ship. You change prices too much too. A person says to themselves Im tired but I will order in the morning. You wake up and the price is higher. The product is worth what its worth. To the best of your ability let people know when you ship and have good tracking. People like that. When I have train, I didnt want to know if you thought you were close to the bathroom or if the room temperature was to your liking. I wanted to know if you learned something. Hope it helps"

Q&A

Is this pillow as firm as a memory foam pillow or is it squishy?
