  • Nice and warm
Size: Queen Color: White
They are warm and good quality. The cotton fabric is of good quality and doesn't lose feathers like other brands. The weight is the right weight for a cozy feeling without being overwhelming.

  • So Comfy
Size: Queen Color: Blue
Hello warm! Great value. Nice baby blue color! Excellent weight and provides good sleep quality. I just snuggle down and wrap this bad boy all around me. It’s so comfy. I would suggest to the manufacturer to make an oversized queen size comforter. The regular queen is a bit small for a 12-14” mattress. It doesn’t quite cover both sides of the mattress. But, cotton and down are a perfect combination. So soft! Great feel on the skin! I have not washed it yet so I have no comment for this. It has held its shape and puffiness rather nicely. Not flat like many! I believe there are some type air pockets or baffles that keep it puffy and airy. Just fluff it and go! I love it despite it being too short on the sides. Works better as a large topper! ... show more

  • Healed a Broken Heart
Size: Queen Color: White
I have a 10 yr old whos favorite blanket was a ridiculous giant down comforter I bought off of Facebook. It was so hard to wash my ex would have to bring it to the cleaners (which to my delight annoyed him). It finally fell apart. But my son was broken hearted so I found this comforter to keep up the tradition. Even ordered 2 so I have one at my house also. Just purchased the queen size. But it is big and fluffy. The outer material is a bit stiff and loud but will soften up with time. My son can happily bury himself in it. Broken heart healed. We will see how it holds up. ... show more

  • Warm and comfortable
Size: King Color: White
This comforter will fluff up after a few days. Super warm and comfortable! There is a slight chemical smell to it but it’s not a “bad” smell per se. I think that will go away after awhile. A great bang for your buck.

  • Amazingly comfortable snuggly duvet insert.
Size: California King Color: White
I've not even put the duvey cover yet bc it looks so nice. The only issues is a spot, that looks more like a burn. ?pn one side of the insert. I just make sure it's on the opposite side. I would've returned for another but I had already placed it on the bed. There were some lose strings that required some hand stiching but didn't mind. The feathers/down are great quality & the 100% outer shell is a must. I got this at a great sale price but probably would not pay full price as there a lot of better quality pieces at the original price at well known stores and good brands. ... show more

  • Weird smell…
Size: Queen Color: White
Quality-wise, this comforter insert feels nice. It’s soft and the weight it reassuring, but the smell? I opened this and let it air for days in an open room and after doing so, this still emitted a bad smell. Strong enough to spill out into the hallway and make the surrounding linens also smell of it. I do not recommend if you’re trying to buy this to accommodate guests (which is what I was preparing our extra bedroom for). ... show more

  • Very warm
Size: Oversized Queen Color: White
I like this comforter because it is nice snd warm, but the weight is a bit heavier than I was expecting. Definitely not an “all weather” comforters, will have to find one a bit lighter for spring and summer

  • Good budget item
Size: King Color: White
Took a while to plump up. Slight chemical smell, which sucks on a dry clean only. Warm and cozy, good for the price. My biggest complaint is I would of payed double for double the duck down in each square. It's kinda thin.
