What Does Comforter GSM Actually Mean?
GSM stands for Grams per Square Meter, which measures the density and weight of the microfiber filling inside your duvet.
- 150 – 200 GSM: Lightweight summer / AC blanket.
- 250 – 300 GSM: The universal All-Season Sweet Spot for Indian AC bedrooms.
- 400 – 500 GSM: Ultra-thick, heavy winter razai replacement for extreme North Indian cold.

3 Features That Prevent Lumping and Cold Spots
1. Baffle-Box Diamond Stitching
Avoid comforters with linear or horizontal stitching lines. Baffle-box diamond or square quilting locks microfiber clusters into individual sealed compartments, preventing the filling from shifting or bunching up at the bottom during machine washing.
2. Microfiber vs Natural Cotton Razai
Virgin conjugated hollow microfiber traps body heat in millions of micro-air pockets while remaining light and breathable. Unlike traditional cotton batting that absorbs body sweat and turns lumpy and musty, microfiber dries rapidly and repels odors.
3. Corner Loops for Duvet Covers
Look for a comforter with at least 4 (ideally 8) sturdy corner loops. This allows you to anchor the inner quilt inside a removable, washable cotton duvet cover so it never bunches up inside.
