Threadmill Supima Cotton Sheets Queen 1000 TC - Hotel Quality Sateen

Our review of the Threadmill Supima Cotton Sheets finds them best for sleepers who want a true hotel-style feel and long-lasting softness. The biggest reason to buy is the authentic 1000 thread count made from 100% ELS Supima cotton, which delivers a rich sateen sheen and a plush hand that improves with each wash. These sheets aim to elevate bedroom style while remaining breathable enough for year-round use, and they come as a complete four-piece Queen set with a deep pocket fitted sheet for thicker mattresses.

Key Features

• 100% ELS Supima Cotton: Provides superior softness and durability compared with standard cotton for a luxurious nightly feel.
• 1000 thread count sateen weave: Offers a velvety finish and subtle sheen that looks like hotel linens while remaining breathable across seasons.
• Generous deep pocket fitted sheet: The fitted sheet fits up to 17' deep pockets with all-around elastic to reduce bunching on thick mattresses.
• Four-piece Queen set dimensions: Includes a flat sheet 92' W x 104' L, fitted sheet 60' W x 80' L + 17' pocket, and two 20' W x 30' L pillowcases for a complete bedding solution.
• OEKO-TEX certified and eco-conscious production: Made without harmful chemicals and manufactured in a wind and solar powered factory, adding sustainability to its premium finish.
• Easy care guidance: Machine wash at room temperature and fold promptly to reduce shrinkage and keep the smooth finish.

Who It's For

The Threadmill Supima set is ideal for people who prioritize a plush, hotel-like sleep surface and want bedding that softens with each wash; couples and individuals with medium to thick mattresses will appreciate the 17' deep pocket and all-around elastic for a secure fit. Shoppers who value long-staple cotton and responsible manufacturing will also find this set appealing because of the OEKO-TEX certification and renewable energy production.

Those who should look elsewhere include buyers seeking a budget ultra-low-cost sheet set and anyone who needs unusually large sizes beyond standard Queen dimensions. There is mixed customer feedback about fit and size, so shoppers who require guaranteed oversized top sheets or custom lengths may prefer to verify measurements before purchasing.
