Nice

Although not as soft as we expected but still a very nice sheet set. Washed well and dried quickly. Unfortunately we left the sheets in the dryer so they are a bit wrinkly for the picture, oops. We love that they come with a little bag which can be reused for anything due the added handles! No waste like some other sets!! The fitted sheet has deep pockets that will wrap around any king sized mattress. The top sheet is bigger than some others sheet sets we have bought, and that is a plus :) Now we don't have to think the other side has more sheet cover than the other, hahaha! The pillow cases are very good sized as well.

Soft & Cozy

The scrunchy part of this fitted sheet is pretty thin. It works for now but time will tell if it will get looser around the mattress. The sheets themselves are really soft and breathable, though. They've held up so far after a few washes, are still soft, and haven't formed any pills yet either.

It’s nice to see sheet sets you cannot see through.

These are very good quality sheets. They are also very warm. While they are on the bed, I only need a blanket to keep warm. No bulky comforter is necessary.. These sheets are also environmentally conscious in that they don’t use plastic in their packaging and they even come in a little reusable bag that can carry small items after the sheets are removed. The color of the sheets is also a rich blue that didn’t fade when the set was washed. Nor did any of the sheets shrink when the laundry instructions were followed. I give these sheets a definite 5 stars. If you are a fan of nice non microfiber sheets, then this set is for you. However, if you prefer the thinness of microfiber sheets, then you may find these sheets stifling and hot. I love high quality sheets that last so this sheet set really resonated with me. Threadmill sheets are my new personal favorite. They look like they could sell for a pretty penny and I Iove them. I don’t regret getting them at all.

Like the feel

These sheets feel somewhere in between cotton and silk. The blue is vibrant and matches the rest of our decor. I like that the fitted sheet has elastic all the way around instead of just the corners although it would even be nicer if the elastic was a little wider. This set came in really nice packaging with statements on the use of environmental friendly packaging such as the cloth bag. Definitely gift-able. I kept the cloth bag as I'm sure we'll find a use for it. Not disappointed at all in this set.

Thick and nice.

Love these sheets. Thick with a slight sheen, color was a bit different than I thought they would be but not a big deal. Deep pockets, easy to put on without a lot of tugging and pulling. You won’t be disappointed with these sheets.

This Linen Set Feels Like Sleeping in a High-End Hotel even after many washes and use

I waited to write this review until after many cold washes and regular use. They remain incredibly soft and comfortable, with great value and barely any wrinkles after washing. The texture is very pleasant to the touch. I’m gradually replacing all synthetic fabrics with more natural, gentle materials. I’ll definitely be buying more sets, including some as gifts.

Fantastic sheets. Thick fabric, tight weave and sturdy construction. Wanted higher thread count but found it’s not necessary. Very pleased with my purchase!

Wow great sheets!

These Threadmill brand cotton sheets are the best sheets we have ever bought. They were a little more than I wanted to pay but I'm so glad we got these. They honestly feel like sheets at a really expensive hotel and we actually think we are sleeping better with them!

Best on the market

These sheets are the best! The color is rich. The sheets are silky smooth. They are ample sizes so there is no tug of war at night. They wash and dry quickly. They are easy to remove and put back on. Ill never by any other brand. Ever!

Deep pockets.

Easy to make the bed with a 14.5 inch mattress. Sheets feel like they are not there.

Too wide—-hang too long on each side.

They certainly are extremely wide for a standard king size bed. I don’t think I like the too plush feel as they do not want to stay tucked under. I think I will step back a couple of steps next time to a little less of the plush.

Frequently Asked Questions

How rare is Supima?

Supima is American-grown cotton that represents less than 1% of cotton grown worldwide, making it one of the rarest premium cotton fibers. Its extra-long staple fibers create exceptional softness, strength, and a smoother feel. 

Will these fit my thick mattress?

Yes. The 17" deep pockets with all-around elastic and large corner gussets are designed for thick mattresses. The all-around elastic keeps sheets anchored throughout the night without slipping.

Will these sheets wrinkle?

Yes. Natural cotton can wrinkle, particularly after washing. Remove them promptly from the dryer and avoid over-drying for a smoother appearance.

Will these sheets soften over time?

Yes. The Supima cotton fibers naturally soften with each wash, becoming smoother and more comfortable while retaining their substantial, luxurious feel.

Why do these sheets feel so heavy compared to other cotton sheets?

The 1200-thread-count Supima cotton is woven with a dense, substantial construction with significantly more fibers per square inch than lower thread-count sheets. This intentional heaviness contributes to the luxury feel and exceptional durability that customers compare to high-end hotel linens.
