GSM means grams per square metre. On a quilt it commonly describes the amount of filling over a given area, but it is not a universal warmth rating across different fibres and constructions.
Read GSM alongside the filling
Two quilts with the same GSM can differ in thickness, drape and feel. Check the filling composition, outer fabric, quilting pattern and any separate warmth classification supplied by the maker. Confirm whether the figure describes filling alone or another part of the product.
| Your situation | Useful comparison |
|---|---|
| Warm room or frequent overheating | Lighter options within the same range, cover fabric and the ability to remove a layer |
| Cooler room | The range's documented warmth options and the bedding already used |
| Shared bed | Individual preferences and whether separate layers are easier to adjust |
Build a flexible set of layers
Rather than buying solely by the largest GSM number, consider a quilt and a removable blanket that can be adjusted as the room changes. Check that the cover does not compress the quilt and that the finished size gives sufficient coverage. Care also affects the choice. A bulky quilt may be difficult to wash and dry in a small home even when its label permits machine washing. Compare the product's care requirements with the facilities available, and avoid treating a seasonal label as a precise temperature guarantee.
