Threadmill Supima Cotton Sheets 1000tc King Set - Luxury Sateen

In this review the Threadmill Supima Cotton Sheets 1000tc King set proves to be a clear choice for sleepers who prioritize a soft, hotel-style feel and long-term fabric quality. The biggest reason to buy is the authentic 100% Supima cotton with a 1000 thread count that delivers a velvety sateen hand and notable durability; the set feels substantial out of the package and becomes softer after washing. These sheets are aimed at people who want a premium, breathable bedding set with a deep pocket fitted sheet that stays in place.

Key Features

• 100% Supima Cotton: The natural extra long staple yarns provide superior softness and strength that improve with each wash.
• 1000 thread count sateen: The dense weave gives a smooth, slightly lustrous finish that reads as hotel-quality on the bed.
• Deep pocket fitted sheet: The fitted sheet includes a 17'in deep pocket with all-around elastic to hold snugly on thicker mattresses.
• 4 piece King set dimensions: The set includes a flat sheet (110'in x 104'in), a fitted sheet (78'in x 80'in + 17'in pocket), and two King pillowcases (20'in x 40'in) for full bedding coverage.
• OEKO-TEX certified and sustainable production: Manufactured in a wind and solar powered factory and free from harmful chemicals for eco-conscious buyers.
• Care and durability: Machine washable with guidance to fold promptly to reduce shrinkage and wrinkles, and constructed to resist pilling and fading.

Who It's For

The set is best for sleepers who want a plush, hotel-like sheet with a durable cotton weave and a fitted sheet that fits deep mattresses. Couples, those with sensitive skin, and anyone who values a naturally breathable fabric will appreciate the pure Supima cotton and sateen finish.

Shoppers seeking a budget thin sheet or those needing a wide range of color/size customization might look elsewhere; also note there are mixed reports about exact fit for some mattress heights, so buyers with unusually thick or irregular mattress toppers should double-check dimensions before purchasing.
