The fabric is silky smooth and drapes nicely over my California King mattress. There are 4 corner ties to hold the duvet in place. I have been looking forever for a duvet and duvet cover that ACTUALLY fits my bed and this is perfect! Thank you!!

No communication with these folks. I bought a silk comforter and cover and after one wash the cover split. Contacted them right away and never got a response.

This is probably the largest duvet cover Down Under Bedding has. Oops, sorry! I have found another super king size duvet cover that was made of cotton. You can check that out here: https://downunderbedding.com/collections/duvet-covers/products/100-cotton-400tc-super-king-cal-king-duvet-cover-110-x-101
I have already used many cotton duvet covers, and they were absolutely fine. But I got impressed with the bamboo cover because of its uniqueness. As I didn’t use any bamboo cover previously, I wanted to give it a try.
Down Under Bedding delivered the product within the promised date, and I am quite satisfied with their service. I promptly opened the package, and the bamboo cover was huge. It had that charm to impress me further and still holds that charm even after using it for weeks.
The price of this bamboo cover was less than the cotton cover I have mentioned before. But there was no compromise in comfort. Though the bamboo cover feels a bit stiffer than the cotton cover when new, it becomes softer and more comfortable after several usages.
Though they say the bamboo fabric is more durable than cotton, I can’t certify this yet because the cover is still new. But it is definitely stronger than cotton covers and provides greater comfort.
This cover has four corner ties to keep the duvet in place. So, there is no struggling at midnight because the duvet has shifted. Even after cuddling under this cover, the duvet stays as it is.
I have washed the duvet cover once and felt one issue with it. The cover gets wrinkled, and I need to press it to bring its charm back. Don’t know why; maybe it’s because of the nature of the bamboo fiber.
Everything else is totally fine till now. I am happy with the purchase and will visit Down Under soon for some bamboo pillow covers.
