Overview

A 100 percent cotton, 300 thread count duvet cover for full or queen size duvets, made in a single-piece design with button closures and internal corner ties. It is OEKO-TEX certified and machine washable.

This is a cover only, meant to slip over an existing duvet insert rather than serve as bedding on its own. The button closure and internal ties are the practical detail here, aimed at keeping the insert from bunching or slipping out during use and washing, in place of a zipper that can snag the fabric over time.

  • 300 thread count, 100 percent long-staple cotton
  • Fits standard full/queen at 92 in W x 90 in L
  • Button closure with internal corner ties
  • OEKO-TEX Standard 100 certified

Who it's for

Fits anyone with a standard full or queen duvet insert who wants a soft, breathable 100 percent cotton cover rather than microfiber. Not for buyers needing an insert or fill included, since this is the cover only.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • 100 percent cotton, softens with each wash
  • Internal corner ties keep the duvet insert from shifting
  • Button closure instead of a zipper
  • OEKO-TEX certified, ships in a reusable cotton bag
What to check first
  • Cover only, no insert or fill included
  • 100 percent cotton will wrinkle and may need ironing
  • No owner reviews included in this batch

Performance notes

The 300 thread count long-staple cotton is woven for a lightweight, breathable feel that the brand says softens further with each wash. Internal corner ties hold the duvet insert in place inside the cover to reduce slipping, and button closures replace a zipper along the opening. Care is by machine wash cold and tumble dry low, and the cover ships in a reusable cotton bag rather than plastic packaging.

What size duvet does this fit?

How does the cover close?
