  • Love
Size: King Color: White/All Season
I love the weight of this comforter. I have a huge one that is really heavy so this is a nice change. The fit is great. I appreciate the loops so i can tie my duvet cover to it. It fluffed fine and is warm and cozy.

  • Finally! In Love with this topper!! Super Plush & Heavy
Size: Oversized Queen Color: White/All Season
The media could not be loaded. when I tell you, I have purchased so many of these pillow toppers and was looking for the ultimate plush topper that felt like all of The five star hotel I had been in I can confidently tell you this is not a paid advertisement. This is the one. To be honest, when I received it, I thought I had ordered the wrong thing because the first thing I noticed is how heavy it was! I mean, considering what it is… I struggled to open the package because it was sealed and the minute I cut it open this thing sprung up and filled out so beautifully. Please take a look at my photos and my video again. This is not a paid advertisement. This is the first pillow topper. I have truly been impressed with. The waffle stitching is very well done. The filling did not take hours to flush up and plump up. It was immediate when I cut the package when you lay on top of this I’m telling you it’s going to be very difficult for you to get up in the mornings because you are going to love crawling into bed And staying in bed. It has Support ties that fits snuggly underneath your mattress. The elastic is at least one inches thick and it stays put as soon as you put your sheets on top. I’ll be honest I need to go back and read the details. I don’t think this is waterproof but if it is, this makes this an absolute must have. I don’t know how well this is going to do a washing machine. It says washable because when I tell you, this thing is so heavy, I cannot imagine washing this and being soaked with water I would definitely recommend taking this to a dry cleaners or a commercial laundry mat because I think this would knock any regular machine out of kilter but again highly highly recommend this purchase well done. ... show more

  • So comfy
Size: King Color: Black/All Season
I love this comforter. It got way more fluffy than I thought it would. It’s heavy so it feels nice with the weight pressing on you all night. It’s on the warmer side of blankets. The quality is exactly what I expected for the price, very good. We have both slept so much better. It could be a bit wider, but still fits nicely. ... show more

  • Nice duvet
Size: King Color: White/All Season
It’s not as fluffy as the pictures show, which wa a bit disappointing and hence the removal of a star. Otherwise it’s nice and warm

Size: Oversized Queen Color: White/All Season
Perfect weight, soft, comfy, and good quality. I put a duvet cover on it to maintain it and give more options for color changes for coordination.

  • Best down comforter I’ve ever had
Size: King Color: Black/Heavyweight
I got the king black heavy weight and upon opening it, it had an odd smell but I sprayed my favorite maverick wicks room spray on it and eventually the smell aired out and I don’t notice it the day after receiving it. When I tell you this thing is comfy, I mean the best down comforter I’ve ever owned! I’m absolutely obsessed! The black color is gorgeous and I love the crinkle crisp sound when you pull it over you. The weight is perfect! It covers our king bed perfectly. I couldn’t be more happy that I got this! I don’t think I’ll put a duvet on it either because so far my Australian Shepard collie mix dogs hair isn’t sticking to it surprisingly and I love the look of it by itself. Buy it, you won’t regret it! ... show more

  • Hugely Disappointed
Size: King Color: White/All Season
First off, the package came several days earlier than it was expected; while this was exciting at first it has certainly made me wonder since. Secondly, the box had a "burnt rubber" smell to it. Opening the box only made the smell worse as I came to find the comforter vacuum sealed. It looked a bit strange but I thought maybe it was just because it'd been in an air tight packaging for a while. I took it out only for it to just flopped open like a wet rag as it tried desperately to rise. It didn't do much after I gave it some time and remained a sad looking. . . wet . . . thing. (??? Don't know how else to describe the sound or look of it unfolding from the packaging in such a sad way.) The color then became quite apparent that it was a strange "old book page" yellow instead of the white I was expecting. I was further surprised to find there were no identifying branding on the comforter or inside the box, there were also no care instructions provided, even on the products tag, just the typical warning to not remove unless the owner of said product. Washing the comforter, on cold and gentle setting, did not get rid of the smell. It took several turn overs in and out of the dryer for it to feel even remotely close to something damp. That 'burning tire' perfume wasn't going to go away regardless of baking soda dustings or long gentle cycles through the wash. After less than 24hrs of having this comforter in my possession, and trying to somehow give an inanimate object the benefit of the doubt, there was no salvaging the situation and so it HAD to be returned ASAP. For a pricy product with rave reviews I was incredibly surprised and hugely disappointed that I received such a poor quality item. It did not live up to the "pictures" depicting the item or the high expectations I had. Edit: I was originally going to wait to open the package until I had moved into my new apartment, but I'm really glad that I didn't wait, I was too anxious to have a nice duvet insert for once. Got my hopes too high but learned to be more thorough when investigating Amazon buys. I also ordered it as a "new" all season weight and I believe I was sent the light weight in a king size instead. The more I look back on the experience it makes me wonder if I didn't receive someone else's reject/return. ... show more
