Beanbags are just fine, sure. But Kumeko has built a better beanbag, and it's called the Snug Chair.
Ever wanted to be swaddled like a baby? Ever wanted to chill out inside of a paddled shell that adjusts to your body position? Or, how about sleeping inside of a laundry basket? The last one, maybe not so much. If you're interested, contact Kumeko here for a quote. Snug: the ultimate nap zone. [Kumeko via Inhabitat]
