We couldn't be happier with this Duvet (comfortor)! It took a long time, and a few snafus before we got the right item, in the right size, but it was totally worth all the headache and extra work!! The silk ticking is ecsquisite, and the down is nicely distributed in each TRUE, closed, baffled box. A little bit of down came out of the packaging when we unfurled the sensual waterfall of fluffily filled silk; but for me this just demonstrated that the clusters inside are of the highest quality I've ever encountered - pristine white, large, fluffy, puffs, without a even hint of feather or quill. It IS warm: Late Fall and Winter. Spring and Summer, probably use ONLY if you keep the AC running (which we ALL should be trying not to do!) if you live up north, you might consider purchasing 2 of these beauties, for the REALLY COLD Winter nights. BTW, FYI - these DO have a couple of seams, that are visible when the duvet is laid out without a cover! If you have OCD, this'll probably drive you bonkers, so make sure you've got a nice, seamless cover, to put over it!!
