The best blanket I’ve owned!
Size: Oversized King(120"x96"), Color: White, Size: Oversized King(120"x96"), Color: White
The first king size comforter to actually fit my king size bed properly. All of my previous comforters were too short/not wide enough. I ordered the oversized king and it’s the best fit I’ve ever seen. It’s lightweight enough for summer but still heavy enough to be warm in the winter. You can feel the quality in this blanket. And it comes with a carrying bag as well!

It’s a great purchase
Size: Full/Queen(90"x90"), Color: White
I purchased this on a whim. I’m glad I did! It is the right weight and provides the warmth I crave at night. Most importantly it is quiet. My old down made a crinkly sound when moving which disturbed my sleep. This one thank God, does nothing of the sort.

It feels like a gentle hug !
Size: King/Cal King(106"x90"), Color: White
This comforter is not too heavy and not too light, and yet it feels just like a gentle hug around your body which feels just right and perfect for a good night's rest. The color is white which is no problem because it's meant for a duvet cover and didn't have a smell at all which I was concerned about with reading other reviews. It is a perfect size for my bed which is king size and lays over just a bit on either side. If you like something that hangs over the bed more I would suggest buying the California King. It's a great value for the money, because you can't put a price tag on a good night's sleep. The only downfall to this comforter is that it feels so good that it's hard to get out of bed! When you purchase this it will be a bit flat because of packaging but once you get it on the bed it fluffs up after a few hours, you can also shake it out a bit if you want it filled out a bit better, I found it easier to put the duvet cover on it first and then gently shake it out over the bed.
