This is designer Aga Brzostek's comfy looking Autumn/Winter Chair. That's a bad name, but a good idea. It's a chair with an integrated sweater blanket cover that you can get into and wrap all around you to stay warm on those cold winter nights. Plus if there's a house fire you're sure to die in it, so there's that.
Thanks to chichi, who agrees the most comfortable blanket is the warm body of a lover. Not too heavy a lover though because then it gets hard to breath but you don't want to hurt their feelings by telling them they're too heavy but you also don't want to die.
