Update: replacement comforter is much better… really impressed with this small business
Size: Palatial King
Update:
The comforter on my bed is now everything I hoped for: fluffy, warm, and wonderfully cozy. Getting here was a two-part story, and it’s the happy ending and the fantastic service that created it that I really want to share.
I’ll be honest, my first comforter was a letdown. It arrived flat and thin and just never really… fluffed into the cozy cloud I was hoping for. I was pretty frustrated, which is why I left my original review.
But then, something really nice happened. The company actually reached out to me directly. They were so kind, listened without getting defensive, and genuinely wanted to make it right. They sent a replacement, no questions asked, and the difference has been night and day.
This new one is exactly what I’d imagined. It has a real, fluffy loft, it’s softer, and after letting it settle, it’s become the full, warm, and comfortable comforter I wanted from the start.
My quick takeaways:
· A small business that stands behind their work. This meant a lot.
· Customer service was top-notch kind, FAST, and professional.
· The replacement is clearly better quality: fuller, softer, and warmer.
· It’s a completely different (and better) experience than the first.
I really value when a company just focuses on fixing things. The way they handled this completely changed my perspective. While the first one missed the mark, their response and the quality of the replacement have made me a happy customer.
I’m glad I gave them the chance to make it right, and I’m finally cozy under the comforter I was hoping for.

Very Nice Comforter
Size: King
So far, very happy with my purchase, (King size comforter). Just received yesterday, unpackaged and put inside my duvet, then realized the instructions recommend you place it in the dryer, (as it comes vacuum packed). I really didn’t feel like messing with the duvet again and yet the comforter still fluffed out very nice. The outer shell is very soft, it has decorative piping around the edges and the filling is evenly spread out throughout all the pockets. One of the nicest features are the tabs, located on all four corners and in the middle of each side, (to tie to the inside of your duvet, if your duvet has the little inner strings) great for keeping the comforter in place.

Just one con…
Size: Palatial King
Loved everything about this duvet: great quality, true-to-size, 8 ties and REALLY big & fluffy. It was just way too warm for us, even during the winter. Wish we could find a duvet this full that was cooler.

Comforter
Size: King
This is the most comfortable comforter I have ever owned! Boutique hotel quality! This comforter is not too warm, yet it keeps us warm and is very lightweight, which I love! We sleep very soundly with this comforter! I highly recommend!

MASSIVE SIZE
Size: California King
I cannot tell you how soft this is but it's like a cloud made of cotton candy! It's so soft and fluffy! In arizona its too hot for a blanket like this most of the time but this is also really cooling. Its been great, I dont have a big washing machine so i take it to the laundromat and its still in really good shape. Its clean and looks so soft and beautiful
