GSM is the single most important number on a wool quilt - and the one most shoppers don't understand. In this guide we break down what 350, 500 and 700GSM actually mean for warmth, and which quilts and duvets suit your climate and sleeping style.
What Does GSM Mean in a Quilt?
GSM stands for grams per square metre - the weight of wool fill inside the quilt. Higher GSM means more wool, which means more warmth:
- 350GSM - lightweight, ideal for summer and warm climates.
- 500GSM - all-rounder, suits most Australian homes most of the year.
- 700GSM - heavyweight winter warmth for cold sleepers and southern winters.
Why Choose Australian-Made Merino Wool?
Woolcomfort quilts are made in Australia from premium merino wool, and wool beats synthetic fills in almost every way:
- Temperature regulating - wool keeps you warm in winter and breathes in summer, reducing night sweats.
- Naturally hypoallergenic and dust-mite resistant - great for asthma and allergy sufferers.
- Moisture wicking - wool absorbs and releases moisture so you stay dry and comfortable.
- Durable - a quality wool quilt easily outlasts cheap polyester fills.

Deep Winter and Cold Sleepers: 700GSM
The Woolcomfort Aus Made Merino Wool Quilt 700GSM Single ($138.59) is a proper winter weight - the kind of cosy you want in a Victorian or Tasmanian July, without piling on three blankets.
Pro tip: Many households run a 350GSM for summer and a 500GSM or 700GSM for winter. Two quilts cover the whole year for less than the cost of one premium doona elsewhere.

Frequently Asked Questions
Is 500GSM warm enough for winter?
For most of coastal Australia, yes - 500GSM handles mild to cool winters comfortably. If you live somewhere frosty or feel the cold, step up to 700GSM.
Can you machine wash a wool quilt?
Always check the care label. Most wool quilts prefer gentle machine wash or professional cleaning. Airing your quilt outside regularly keeps it fresh between washes.
Wool vs down vs polyester - which is best?
Wool is the best all-rounder: it regulates temperature better than polyester and handles moisture better than down, while being naturally hypoallergenic.
