Soft, Luxurious, Thick, Durable, and worth every dollar!

If you’re looking for thick, durable sheets that will last through years of washes, these are the sheets to buy. If you like soft, heavyweight sheets with a substantial feel instead of thin flimsy material, these are absolutely worth it. About every 6–8 years I end up searching for another quality set of sheets, and it’s always difficult to find the level of quality I want without spending $300 or more. These sheets genuinely feel top quality. They’ve stayed soft, thick, and comfortable without pilling or balling up, even after a huge number of washes. Highly recommend for anyone wanting durable luxury sheets that actually hold up long term. The slight wear shown in the photo is actually from my previous set of sheets that lasted around 8 years, not these. That’s the level of durability I look for, and these finally feel comparable! 100% Recommend!

Thick, Heavy Luxury

If you are looking for 100% luxury Supima cotton sheets that are thick, heavy and leave plenty of length to tuck under the end of the mattress then look no further. These are the best I have found.

WOW! I have never had such comfort while sleeping! I also have never had a 1200 thread count sheet set before…. This product and quality of sheets surpasses all others! They really are cooling, soft and can fit deep mattress as well. It’s a must have for me and my husband! Luxury for sure!

Great sheets!

After they quit making Fieldcrest sheets, I bought so many sets that just didn’t measure up. These Threadmill sheets are as close as I could get. I love the fact that they stay crisp, even after laundering many many times

Nice soft and thick sheets!

Nice and thick sheets. I like the higher thread county because they last longer and feel better to me. They are 100% cotton and wash well.

Wonderful thick cotton sheets

These thick cotton sheets are soft & comfortable. Love the color I pick (SeaFoam). Fitted bottom sheets have large corners and they have extra give for thicker mattress. The flat sheet is long and has extra length to tuck well under mattress. Elastic goes completely around bottom sheets. 2 Thick pillow cases fit well with extra length. I’m very picky about my cotton sheets and these are wonderful and well worth the money.

LOVE

Absolutely LOVE these sheets. They feel like our favorite set that we bought from Dillards over 20 years ago ($350). A little on the thicker side (not enough to make you feel hot) but that is one of the reasons I like them so much. Excellent price too!

These are luxurious, the color is really nice and they feel amazing to sleep in. In addition, the fit is perfect with enough of the sheet being tucked under the mattress to keep it perfectly in place.

Updated Review one year later. Still feels like luxury

Updated Review: one year later. These are the best sheets I have purchased in years. They have held up, no rips, no tears. The elastic is perfect around the corners They did not shrink excessively after washing, as the other brand sheets heavily advertised as an alternative under this listing. They have definitely become softer after a year of washing, but still retain their heavier, more expensive feel. In fact, the girl at the dry cleaner's couldn't stop raving over them. How beautiful, how thick and luxurious. She thought they were a way more expensive brand. I love to sleep under sleek, crisp sheets with no wrinkles, so I have them dry-cleaned. I am so pleased with these that I think I'll try one of the colour sets. I often find the colour version does not have the same feel as the white, but I've been so impressed that I'm going to give them a try.

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.
