    • 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

    • The best comforter I’ve purchased hands down!
Size: Queen Color: Black/Heavyweight
Definitely worth the purchase! Extremely warm, comfortable and snuggly!

    • 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

    • 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

    • Beat down comforter for the price!
Size: Oversized King Color: White/All Season
Review Image by Amazon Customer Amazon Customer
I have an Eastern King bed, it’s wider than a Cal King. And this down comforter is the absolutely perfect size for it! I wanted a comforter that covers all sides of the bed down to the bedskirt, since all the others ones I’ve had only barely come down halfway past the sides of my mattress showing the sides of the bed sheets. I got the oversized king one and it’s perfect! Also keeps my husband and I warm at night but not overly warm. I laid it out after removing from package for 24 Hours and gently padded it all over with my wooden back scratcher to help it fluff up nicely. So happy I purchased this beautiful comforter and great price!!!! ... show more

    • The Perfect Comforter
Size: King Color: Grey/Heavyweight
The packaging was very deceiving. I was afraid that I had made a sizing mistake. However, once I got it fully expanded and ran it in the dryer for 20 minutes, it is the most amazingly comfortable blanket I own. This works perfectly when you get it in the extra size.

    • The Heavy Weight is the ONE if you wants heavy, super super warm, down comforter
Size: King Color: Grey/Heavyweight
Yes! This one. If you want a heavy weight down comforter, this is THE one. I've had quite a few high end feather and down comforters, but this one is hands down one of the best. If you select their regular one, vs the heavy weight, I have a feeling that you'll also love that one. Great quality.

    • 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.
