Kotton Culture 120x120 Super King Plus Duvet Cover Set - Luxury Cotton

Our review of the Kotton Culture 120x120 Super King Plus duvet cover set finds it best for sleepers who need an extra-large, hotel-style cover that stays cool and feels soft. The single biggest reason to buy is the combination of a true extra-large fit and 100% Egyptian cotton with a 600 thread count sateen weave, which delivers a noticeably smooth, breathable surface and a substantial feel that suits oversized comforters up to 118in x 118in. It is a duvet cover set for those who own oversized inserts and want a zipper closure and internal ties for a secure fit.

Key Features

• Extra-large fit: The 120in x 120in size is designed specifically for Super King Plus or Super Oversized King inserts up to 118in x 118in, preventing gaps and bunching common with smaller covers.
• 100% Egyptian cotton: The extra-long staple cotton with a sateen weave gives a soft, breathable surface that helps keep sleepers cool and comfortable year-round.
• 600 thread count: A dense sateen construction balances durability with a smooth, slightly lustrous finish that wears well over time.
• Zipper closure: A hidden zipper makes inserting or removing the comforter easier than button closures and produces a cleaner edge.
• Seven internal ties: Multiple corner and side ties keep a large insert aligned and reduce shifting, so the comforter lays flat overnight.
• Easy care: Machine washable and designed to resist fading, pilling, and shrinkage when laundered per instructions, simplifying upkeep for a large bedding set.

Who It's For

This duvet cover set is ideal for owners of extra-large or custom oversized inserts who need a true Super King Plus size and a hotel-quality feel. Couples with larger beds or anyone who prefers a roomy, full drape over the mattress will appreciate the 120in x 120in dimensions and the secure internal ties.

Shoppers who use standard king inserts should look elsewhere because the cover is not compatible with standard king comforters. Also, buyers seeking a budget microfiber alternative or those who require decorative closures may prefer different styles.
