    • I love this comforter
Size: Oversized King Color: White/All Season
It’s not as fluffy as pictured but I was actually happy with that. It’s the perfect weight size and super comfortable and warm

    • Great!
Size: King Color: Grey/Heavyweight
This down comforter is very good and very warm especially in cold temperatures. It’s fluffy and lightweight, but it is very efficient. I am very happy with my purchase.

    • Affordable, poofy, love it
Size: Twin Color: Grey/Heavyweight
The cotton material is not heavy duty but it's going to keep me toasty this winter. I searched long and hard, high & low, on many different sites. I had a limited budget, but my RV has no heat & after an injury that's kept me from working, early SS says I can't work yet. I needed something to keep my dogs & i from freezing. The price for what I got was a gogodsend. Its gonna be zero tonite so arrived just in time. I am exceptionally pleased. I have had down alternative comforters in the past, but they just werent as warm. This down is certified responsibly harvested so its even more of a bargain. I bought a verybpretty duvet cover to keep it protected too. Im giddy. And warm! ... show more

    • Very Warm
Size: Full Color: White/Heavyweight
I swapped out my electric blanket for this giant marshmallow . I had to wrestle it into submission, in order to get the Duvet cover on it. A task I'd rather go the rest of my life without doing again. It's constructed well, thick heavy, soft, exactly what I was looking for. It looses tiny feathers here and there but they don't poke me, like some cheap down blankets. There's nice spot to tie in your duvet, at each corner. All in all this was a good purchase. ... show more

    • Durable and long lasting, cool and comfortable
This has become my favorite summertime comforter. It's simple but well made, cool and comfy, and washes well. Been using it over a year now and it still comes out of the washing machine looking like new. definitely worth the money.

    • Fantastic!
Size: Full Color: White/Heavyweight
This comforter is very high quality! The cotton cover is good and dense so that no fuzz escapes at all! The comforter also has, double sewn seams and, the baffling is done with expertise. Because it didn’t cost as much as all down, I selected this one that also has feather fibers and small feathers. I had it out for a week to see if it would leek with normal movement. It did not. We put it in a cotton duvet cover and now my Mother (who is always cold) is warm all night! ... show more

Size: California King Color: White/Heavyweight
I bought this California king duvet insert and I will never look back! By far the coziest duvet ever. Pro tip: always buy a Cali king insert with a king duvet cover for optimal fluffiness!

    • Did not like the feel
Size: King Color: Grey/Heavyweight
This product fluffed up nice and was quite heavy. However, the outside felt sort of plastic ky and was loud. I probably could of purchased a cover but for the price and color options, I was expecting to use as is. I returned for a different option. The color was a beautiful charcoal Grey though.
