Great duvet insert
Size: King, Style: Light
Perfect duvet insert. I got a pretty expensive duvet to cover this and they worked great together. The fit was perfect and I didn’t feel like the duvet was smaller than its cover. This was a cheap option that keep us warm while not being too think. This product is also breathable and recommend if you live in a place that transitions from hot to cold often.

Great mid-weight comforter
Size: King, Style: Light
Great comforter, especially for the price. I put it in the dryer for a bit when I first got it and it became nice and fluffy. Perfect mid-weight duvet.

Warm, cozy, soft, 💜 love
I don't leave reviews very often (yes that is cliche) I just don't have time. I have been debating for a few months one what I actually wanted to do with my bedroom. Spring is coming and the dark is getting to me and wanted to still get an elegant feel. I have some light baby blue around in my other comforter but I needed lighter brighter. I saw this and how SOFT is looked and I LOVE soft and cozy, who doesn't? I am so glad I took the chance. With that I also ordered the pillow....what I thought were pillows but didn't read very clearly they were just the covers so I ordered pillows then the picture I knew would still be elegant but be able to tie all the peices in and OFF the internet. Sometimes colors are not the same online as in person since monitors are always different shades of a color.
Now on to this comforter. I didn't realize it came with the pillow covers. 💜 the set comes vacuum sealed but it is heavy when vacuumed. I undid the packaging a day later when I had time to wash. The cover flew out and I was perplexed, it's a pillow cover!!!! Awesome!!!! Ohhh there's 2, woohoo! Omg it's so soft. Oh I'm in heaven. Mmmmm hugging the pillow cover, I knew this was my kinda softness bed comforter. It is not LIGHT weight like say a throw blanket but it is light vs heavy bulky goose downs even though they say those are light. And when you wash it, its def not heavy if u spin the water out at super high setting on ur washer. I was able to carry it to the dryer fairly easy 20 ft away.
This is by far the BEST comforter I bought in my life. I am a hoarder when it comes to comforters. Thinking if I'm ever homeless I'll have lots of somethings to keep me warm. For the price and the quality, (the batting inside doesn't shift when washing) this will be another purchase in the future in another color so I can start a soft collection. I usually give my comforters that I dont use ( the oldest but still perfect condition) to a friend or homeless.
Great product!!!!

Soft warmth for cold nights
Color: Charcoal, Size: King
This bedding set with faux mink fleece and sherpa backing is perfect for cold weather or low-heated rooms. It’s ultra-soft on both sides, and the down-alternative fill keeps warmth in without feeling heavy. The reversible design lets you switch up the look, and the stitching holds up well.
Even after several washes, it keeps its texture and shape. No clumping or loss of loft. A practical choice for anyone who wants comfort, warmth, and simple style.

Great bedding at a great price!
Color: Tide Pool Blue, Size: King
I can’t believe how great this is for the price! Super soft, comfy and very warm. Perfect for wintertime. I don’t think I’d use it for other seasons…but it’s great right now.
