Cal California Super King: 110" X 100" or 279.4 cm X 254 cm

DOWN UNDER BEDDING brings you California Super King Size duvets designed for every season! Whether you are looking for a lightweight summer duvet, a heavier-weighted duvet for winter, or one that can be used all season long, these specialized duvets bring you all the extra comfort required for any type of climate.

Each duvet is made with a 289 thread count 100% cottonouter shell that is durable, soft, and breathable. The filling is made from 100% goose down that is processed and cleaned to the standards of the Down Association of Canada . Each specialized duvet has different fill weights to accommodate the season it is designed for.

The duvets are constructed with a 12" baffled box design that helps prevent fill from shifting and provides an even amount of thickness throughout the comforter. A double-stitched white cord all around the duvet delivers extra reinforcement. All the duvets are equipped with corner ties which help keep the comforter inside a duvet cover. These duvets are proudly finished and filled in Canada.

California Super King Size Duvet:

California Super King Size duvets are designed for high-contoured king mattresses that are too tall for a standard king duvet. The added length allows the duvet to properly hang off the sides of the bed. A duvet with more coverage is great for sharing, as the excess fabric makes it ideal for two people.

Lightweight Summer Comforter (25 oz Fill Weight)

A lighter and cooler duvet for hot summer. Treat yourself to something designed to help you sleep more comfortably in the summer. No more settling for a flat sheet. You can have all the comfort you love from a duvet, even during hotter nights. This is a thinner and lighter duvet with less fill weight, creating a cooler and more enjoyable duvet experience for warmer climates.

All-Season Comforter (35 oz Fill Weight)

Designed for all-season use, you can enjoy this duvet all year round. Crafted perfectly to keep you nice and toasty in the winter but is still cool enough for summer use. This is the best choice for those who prefer to use one duvet all year instead of switching between winter and summer duvets. The need for only one duvet is less costly and saves on storage space too!

Heavyweight Winter Comforter (45 oz Fill Weight)

This duvet is crafted with extra filling to create a hot experience for winter climates. Designed for colder days when a heavier and much more insulating duvet is required. The extra filling within the duvet gives the blanket higher insulation properties by creating an abundance of tiny compartments inside the down to trap and hold the heat within. This is one of the warmest duvets on the market and is surely the best choice for winter.

Care Instructions:

Do not wash this down-filled product. This could affect your duvet's quality and encourage the filling to leak out.
Spot cleaning is recommended. Use cold water and a small amount of mild detergent. Allow the spot to air dry.
Refresh the down inside the duvet by letting it hang outside in the sun for a few hours. This will help disinfect the down.
Always use a duvet cover with your comforter as this protects it from stains and dirt buildup, keeping it fresher and looking newer for longer.

Teresa MacIntosh
Well made and soft

Purchased the all season weight Cal king size. Beautifully fits my queen size mattress that is extra high. I find the filling adequate and should be very comfortable in warmer weather, but I find the duvet too cool for winter and spring weather. Should have purchased the winter weight. That said it is a beautifully made duvet.

Jill C
Soft, warm and luxurious

I live in the Lower Mainland of BC and the medium weight of this blanket is perfect for both myself (notoriously cold sleeper) and my husband (a warm sleeper) in our winter climate. Hoping it will still be fine come the hottest days of summer but if not, I will be back to purchase the summer weight... that's how much I love it! Delivery was quick too.

Thank you very much for a beautiful authentic organic review Jill.
