Alaskan King Comforter
Comforters and duvets sized to fit the massive 108" x 108" Alaskan King mattress. Finding the right oversized comforter ensures proper coverage and a polished bedroom look.
Buying Tips
- Look for comforters at least 120" x 120" to ensure proper drape on all sides
- Consider a duvet with removable cover for easier washing
- Down alternative fills are easier to find in oversized sizes than genuine down
- Check if the comforter is machine washable–oversized items may require commercial washers

Fill Types and Warmth
Alaskan King comforters come in several fill types, each with different warmth and weight characteristics:
Down alternative (polyester fill)
$150–$300The most common option at this size. Lightweight, hypoallergenic, machine-washable. Good for moderate climates and people who prefer easy care.
Down (goose or duck)
$300–$600+Warmer, lighter, and more luxurious than synthetic fills. Requires dry cleaning or a very large capacity washer. Limited availability in 108" × 108".
Bamboo or microfiber
$150–$300Moisture-wicking and lightweight. Good for hot sleepers. Available from OCOCHI.
Wool
$400+Natural temperature regulation – warm in winter, cool in summer. Heavy. Very limited in Alaskan King size.
Important consideration: An Alaskan King comforter is enormous. Make sure your washing machine or dryer can handle it. Many owners use a commercial/laundromat machine for washing oversized comforters, or choose a duvet with a washable cover instead.
Duvet Cover vs Comforter: Which to Buy
At Alaskan King size, a duvet with a removable cover is often more practical than a standalone comforter:
Duvet + cover advantages
- ✓Easier to wash – you wash the cover, not the entire filling
- ✓Easier to change styles – swap covers seasonally
- ✓Standard washing machine can usually handle just the cover
- ✓If the duvet insert gets too warm/cool, swap inserts without replacing everything
Standalone comforter advantages
- ✓Simpler – no inserting duvet into cover (which is a workout at 108" × 108")
- ✓Often cheaper upfront
- ✓No bunching or shifting inside a cover
If you go the duvet route, check that the cover and insert dimensions match. An Alaskan King duvet cover should be 108" × 108" or slightly larger (110" × 110") to accommodate the fill without being too tight.
Frequently Asked Questions
What size comforter fits an Alaskan King bed?
You need a comforter specifically made for Alaskan King beds, typically 120" x 120" or larger. Standard King comforters (104" x 88") are far too small and won't cover the sides properly.
Where can I buy Alaskan King comforters?
OCOCHI, Alaskan King Bed Company, and Big Mattress Co. offer Alaskan King comforters. Expect to pay $200–$600 depending on fill type and quality.
Can I use two King comforters on an Alaskan King bed?
Some couples use two separate King comforters side by side (the 'Scandinavian method'). This works but leaves a gap in the middle and doesn't look as polished as a single oversized comforter.
What's better for an Alaskan King: comforter or duvet?
A duvet with a removable cover is often more practical because you can wash the cover without dealing with the massive comforter itself. However, quality Alaskan King duvet covers are harder to find than comforters.
