Winter Quilts

Australian winters vary dramatically — from mild coastal Sydney nights around 10°C to sub-zero conditions in alpine regions and inland areas. A good winter quilt needs to match the local climate, not just a generic "winter" label. This guide covers GSM ratings, fill materials, how insulating capacity varies between materials at the same weight, and how to choose between down, wool, and synthetic options.

For the complete guide to quilt types, construction, and warmth ratings across all seasons, see the Australian Quilt Buying Guide.

Quick reference by climate:

• Mild coastal (Sydney, Brisbane, Perth) → 350-500 GSM, wool or down
• Cold southern cities (Melbourne, Adelaide, Hobart) → 450-600 GSM, wool, down, or high-GSM microfibre
• Alpine / inland frost areas → 550-800 GSM, or layer a mid-weight quilt with a wool blanket
• Heated bedrooms → 350-450 GSM is usually sufficient regardless of location

This is the single most important concept in choosing a winter quilt. Different fill materials have very different insulating capacities per gram. Down traps far more air per gram than cotton or polyester, which is why a lightweight down quilt can feel warmer than a much heavier cotton quilt.

What this means in practice:

• A 500 GSM goose down quilt provides roughly equivalent warmth to a 700-800 GSM polyester quilt — at less than half the weight
• A 350 GSM alpaca quilt feels warmer than a 450 GSM wool quilt, because alpaca's hollow-core fibres trap approximately 20-30% more insulating air per gram than wool's crimped fibres
• Wool still outperforms cotton and polyester at the same GSM — its natural crimp creates effective air pockets, and it actively regulates temperature by releasing heat when warm

What is TOG?

TOG (Thermal Overall Grade) is a UK/European measure of thermal resistance — how effectively a quilt prevents heat from passing through. Higher TOG = warmer quilt. It is independent of weight, which makes it more accurate than GSM alone for comparing warmth across different materials.

• 1-4.5 TOG → Summer / lightweight
• 4.5-10.5 TOG → Spring/autumn / all-season
• 10.5-15 TOG → Winter

Australia doesn't use a standardised TOG system — most brands use GSM and a warmth rating (e.g., "warmth level 4-5" or "winter weight") instead. Where TOG is listed, it's useful for direct comparison. Where it isn't, use the material + GSM combination as a guide. For the full warmth rating chart, see the Australian Quilt Buying Guide.

Key terms for down quilts:

• Down-to-feather ratio — expressed as a percentage (e.g., 50/50, 80/20, 85/15). The higher the down percentage, the softer, loftier, and warmer the quilt. Feathers add support and structure but less insulation
• Fill power — measures the volume (in cubic inches) that one ounce of down occupies. Higher fill power = better insulation with less weight. Premium goose down reaches 600-800+ fill power
• Down-proof casing — high thread count cotton fabric (233+ TC) that prevents down escaping through the shell. Essential for durability

Downia stocks both duck and goose down quilts — from the Summer Lightweight 30% Duck Down through to the Gold Collection 85% White Goose Down. Snuggledown offers Hungarian White Goose Down quilts for peak luxury. See all feather & down quilts and read customer reviews.

One of the most common bedroom conflicts: one partner sleeps warm, the other sleeps cold. Dual-zone (or "his and hers") quilts solve this by using different warmth levels on each side of the same quilt — a warmer fill or higher GSM on one side, and a lighter, cooler fill on the other.

• Kelly & Windsor Gold His and Hers Alpaca Quilt — different alpaca fill weights on each side, available in Queen and King
• Couples Dual-Zone Tencel Quilt — Tencel fill with different GSM ratings per side
• Dreamaker All Season 2-Piece Wool Quilt — two separate quilts that clip together, allowing different seasonal weights

This approach eliminates the nightly tug-of-war over covers and means neither partner compromises on comfort. Browse the full dual warmth quilts range.

Other layering options:

• A fleece or cotton blanket at the foot of the bed for extra toe warmth
• An electric blanket (underblanket) to pre-warm the bed — then switch off and let the quilt maintain warmth
• Warmer sheets — flannel or brushed cotton sheets in winter create a warmer base layer than percale

How a quilt is stitched affects warmth distribution. For winter quilts this matters more than for summer:

• Sewn-through (channel or diamond) — stitching goes through both layers. Keeps fill evenly distributed. Can create thin "cold spots" along stitch lines. Suitable for mid-weight winter quilts
• Baffle box — internal fabric walls create sealed boxes that allow fill to loft upward without shifting. Best for heavy winter quilts — eliminates cold spots and maximises insulation. Standard construction for premium down quilts
