Product Overview
The STWIENER Alaskan King Comforter is an extra large down alternative comforter measuring 120 by 132 inches. The listing says the extra width suits a family of four and avoids the tug-of-war at bedtime, and that it drapes well over the sides of a large bed.
The cover is 100% microfiber, which the listing describes as soft and breathable, like a hug, and quiet, in contrast to noisier fabrics. The color on this listing is dark blue.
The fill is 200 GSM microfiber down alternative. The listing says it is fluffy and breathable, suited to hot sleepers, and a good choice for people who cannot use goose down and feather bedding because it avoids the odor and sharp quills of feathers.
The listing says the comforter is vacuum packed and may need fluffing, which is common for rolled and compressed bedding.
Score Breakdown

Scores are consistent editorial judgments, not laboratory measurements, and we did not receive a paid sample.
Key Features
120 x 132 inches, wide enough for shared sleep.
100% microfiber that is soft and breathable.
A fluffy down alternative without feathers.
Holds the filling in place.
Secure the comforter in a duvet cover.
Machine washable on a cold gentle cycle.
Design and Build Quality
The comforter measures 120 inches by 132 inches. It is large enough to cover an Alaskan King bed and, according to the listing, even a California King bed, so check your mattress size before buying to avoid too much overhang.
The shell is 100% microfiber, which is a synthetic fabric that is soft, resists wrinkles and is easy to clean. The fill is a 200 GSM microfiber down alternative, which mimics the loft of down without animal feathers.
Construction uses box stitching to hold the fill in place and prevent filling from leaking or bunching. The listing says the hem is durable and not easily worn.
Four corner rings and 4 side loops allow the comforter to be fixed inside a duvet cover, so it can be used as an insert. The listed weight is about 8.8 pounds.
Performance in Everyday Use
Comfort comes from the loft of the fill and the softness of the cover. The listing describes the comforter as lightweight and fluffy, which suits people who prefer a lighter feel, and says it is breathable for hot sleepers.
Size is the main practical benefit. At 120 by 132 inches it is much wider than a standard King comforter, so two people can have plenty of cover each, which helps with night-time tugging.
The comforter arrives vacuum packed. The listing says it may not fluff up on opening and suggests drying it in a dryer or in the sun for a few hours. This is a normal step with compressed bedding.
Care is simple. Wash cold in the washing machine on a gentle cycle and wash separately, and use low temperature steam ironing if needed. A large comforter may need a commercial machine, so check your washer capacity.
The listing does not state warmth ratings, so winter-only sleepers may want to check the fill weight before buying.
