Perfffff
Color: White, Size: Oversized King, Color: White, Size: Oversized King
So very comfy! I did not expect to love this as much as I do. I was worried about it being too hot. It’s not. I was used to sleeping with a quilt but this is so comforting, the weight of it is so cozy & perfect. I sized up with oversized king for my king size duvet cover. Its so fluffy and perfect for the aesthetic I wanted

So cozy!
Color: White, Size: King, Color: White, Size: King
I absolutely love this comforter! It's very cozy, soft, and fluffy! I bought it for a duvet that I have and it fits it perfectly. It has loops on all four sides to tie a duvet and comforter together, which is really helpful. This comforter is also breathable so it helps me sleep better at night because I'm not getting overheated. The color and appearance is true to the pictures it displayed. It also seems to be quite durable and good quality. I would definitely recommend for anyone needing a new cozy comforter!

Perfect summer blanket for hot sleepers
Color: Olive Green, Size: Oversized King
Oh my, we love this blanket so much. It's soft it's warm in our 65° bedroom at night I steal sometimes get too hot underneath of it and I have to uncover but it's not as bad as the one I had replaced it with which is going to be our winter blanket this is going to be our summer blanket. Can't say enough about how soft and cozy and comfortable this is it's not a heavy blanket which is not what we wanted anyways and when I make the bed it looks very nice and not puffy.

Solid Affordable Duvet Insert Comforter
Color: White, Size: Queen
This is a great affordable all-season duvet insert comforter. There are multiple tie downs to attach to the duvet cover, not just the 4 corners. It is soft and washes well. It's plenty warm in the cold but might be too much during the hotter months. I live in San Diego where the average yearly temperature is at least 70 degrees. During the majority of the year this comforter ended up being too warm for me. I've used it for nearly 2 years but just replaced it with the much thinner Bedsure cooling comforter. If you're a hot sleeper or live in a warm climate, I'd recommend that product. This is still a good comforter, just not for me.
