Care Guide

What Makes Our Duvet Inserts Unmatched?

We created a naturally soft fabric for our duvet shell by precisely weaving the highest-quality, 100% organic cotton threads. With our bafflebox construction, we turned fill density into a science, tailoring the exact amount of PrimaLoft® needed to support your climate and sleep temperature.

Allergy-Friendly, Down-Like Loft.

We partnered with the experts at DOWNLITE to bring the experience of a down duvet to life using PrimaLoft® Luxury Down Alternative®—a premium, down-like fiber that mimics the weight and gentle loft of down in an innovative, hypoallergenic fill.

The Finest 100% Organic Cotton on Earth.

We preserve the purity of our long-staple, 100% organic cotton by choosing not to use any harmful pesticides, GMOs or toxins like formaldehyde in the making of our products. It’s better for you and the planet.
