Olive + Crate Bamboo Comforter King Size Duvet Insert 102"x90" — Breathable, Recycled-Fill, Cool-to-Touch

The Olive + Crate Bamboo Comforter King (102" x 90") is a breathable, planet-conscious duvet insert that blends viscose from bamboo and recycled polyester for a soft, cool, all-season bed layer.

Designed to mimic the loft and comfort of traditional down without animal products, this king-size duvet insert combines a silky bamboo-derived shell with a lightweight, fluffy fill. It’s built to fit standard king duvet covers and provides temperature-regulating performance that works well for year-round use. Thoughtful details like box stitching and corner ties keep the fill evenly distributed and secure inside your cover.

How does this comforter feel and sleep during warm nights?

The bamboo viscose outer shell promotes airflow and feels smooth against skin, reducing cling and trapping less heat than many synthetic covers. The 60% recycled polyester/40% bamboo viscose fill keeps loft while allowing moisture to move away from the body, helping sleepers stay comfortable through the night.

• Silky 100% viscose from bamboo exterior for cool-to-touch comfort
• Breathable fill blend that resists overheating
• Box stitching maintains even loft across the insert

Will it fit and stay in place inside my duvet cover?

This insert is tailored in a true king dimension (102" x 90") to fill standard king covers without excess bunching. Corner ties inside the comforter fasten to cover loops so the insert stays put and maintains an even appearance on the bed.

• True king sizing for full coverage and flattering drape
• Corner tie attachments to prevent shifting inside covers
• Box-stitched construction prevents fill migration and cold spots

How easy is it to clean and care for this duvet insert?

Made for everyday living, the comforter is machine washable and engineered to retain softness after repeated laundering. Low-maintenance care makes it suitable for households with pets, kids, or frequent use—simply follow the label instructions for best results.

• Machine washable for convenient at-home cleaning
• Durable fill that stays plush wash after wash
• Colorfast white fabric blends easily with most covers and décor

What makes this an eco-friendlier option?

The shell uses 100% viscose sourced from bamboo, and part of the fill is recycled polyester, which lowers reliance on new synthetic fibers. The comforter carries Oeko-Tex Standard 100 certification, signaling that the textiles were tested for harmful substances and made with sustainability considerations.

• Outer shell: 100% viscose derived from bamboo
• Fill: 60% recycled polyester and 40% bamboo viscose blend
