No mention anywhere of down and feather percentage so my guess based on price alone is it's probably only like 10% down.

Try Bullseye Deals on eBay (Target's liquidator). It usually has good deals, though it did take me about a month to outfit my new bed at the prices I wanted.

I was going to say, when it comes to brands you have never heard of , what are the chances that this contains nothing that it says it does.

While some of us here just refuse to accept this brutal fact

The only review that doesn't sound fake reports this to be two flat sheets with only a few stray feathers in each pocket.

Hundreds of reviews that have the same formatting all have the same exact message

I'm also extraordinarily suspicious of the plethora of immediate thumbs ups... there is NO WAY fifty people with knowledge of this made up brand and one specific dubious product instantly found this post
