Material & Weave Science
A comforter has two key parts: the shell (outer fabric) and the fill (what’s inside). Together, they shape how it feels and performs.
The shell is defined by its:
- Fabric – like cotton, microfiber, or linen
- Weave – percale or sateen
- Thread count – 200, 300, or 400 TC
The fill can be either down or down alternative, each offering its own feel and level of warmth.
These factors influence your comforter’s breathability, moisture-wicking ability, texture, weight, and warmth.
At Cahoosh, we partnered with fabric and sleep experts to design comforters tailored to different sleep personalities, so choosing yours is effortless.
