Choosing a down comforter comes down to a few key factors: fill type, fill power, fill weight, construction, and size. This guide covers each one clearly so you can find the right fit for your sleep style and bedroom. Prefer a shortcut? Take our Down Duvet Quiz for a personalized recommendation.
1. Goose down vs. duck down
The most important difference is fill power potential. Goose down clusters are larger, which allows for higher fill power (up to 950 loft) and a loftier, lighter feel. Duck down is a great value option and performs similarly at lower fill powers (600–800 loft). Both are warm, breathable, and durable when properly cared for. See the full comparison →
2. Fill power and fill weight
These two terms are often confused, but they measure different things:
• Fill power measures the quality and loftiness of the down. Higher fill power = fluffier, lighter, and warmer per ounce. Linens Delight carries options from 600 to 950 loft.
• Fill weight is the total amount of down inside the comforter (measured in ounces). More fill weight = more warmth, regardless of fill power.
Together, these determine how warm and lightweight your comforter feels. Warmth levels are also measured in TOG ratings — see our TOG guide for a full breakdown by season.
3. Season and sleep style
Match your comforter to your climate and how warm you sleep:
• Hot sleepers / warm climates: Summer (2–5 TOG), lower fill weight
• Most sleepers / year-round: All-season (8–9 TOG)
• Cold sleepers / cold climates: Winter (12–14 TOG), higher fill weight
All Linens Delight duvets are available in multiple fill weights. Browse our full comforter collection to filter by warmth level.
4. Baffle box construction
Look for baffle box construction — a grid-like internal stitching that keeps down evenly distributed across the entire comforter. Without it, fill shifts toward the edges over time, creating cold spots. All Linens Delight duvets feature baffle box construction for consistent warmth and maximum loft.
5. Choosing the right size
A well-fitted comforter should drape over the sides of your bed with enough coverage for two people. Dimensions can vary by manufacturer, so always verify measurements before purchasing. Our size chart outlines exact comforter and duvet cover dimensions.

6. Pair it with a duvet cover
A duvet cover protects your comforter from dust, oils, and daily wear — and makes cleaning simple. Because down bedding requires professional cleaning, a cover you can toss in the wash regularly significantly extends the life of your duvet. It’s also an easy way to refresh your bedroom’s look. Browse our duvet cover collection.
7. Don’t forget the pillow
A great comforter deserves a matching pillow. Down pillows come in soft, medium, and firm options — the right choice depends on your sleep position. Side sleepers generally need firmer, higher-loft support; back and stomach sleepers do better with softer, lower-loft options. Take our Down Pillow Quiz or explore our Signature Pillow Collection.
8. Certifications to look for
When buying down bedding, look for these certifications as indicators of quality, safety, and ethical sourcing:
• DOWNMARK® (Down Association of Canada) — verifies genuine down content and quality standards set by the Canadian Government
• OEKO-TEX® Standard 100 — confirms the product is free from harmful chemicals, important for sensitive skin
• RDS (Responsible Down Standard) — certifies ethical and humane animal sourcing
All Linens Delight products carry DOWNMARK® and OEKO-TEX® Class 1 certification. View our certifications →
