Looking for a "most agreeable sitting sensation"? These water-resistant indoor and outdoor modern bean bags, Do Nuts, look best suited for kids, but they also have heating properties appealing to everyone (filled with EPR "beans" that absorb and give back the body's heat).

Coolhunting has a sassy little write-up about these comfy seats, worth reading for the idea that they "hug your body like Madonna in a pink leotard." A Belgian product, distribution sites so far only include Europe and Mexico, but the site does not list product pricing or shipping costs. Anyone know of a similar product stateside??

Standard size runs 120 x 45 cm, but you can customize any size you like from the Sit on It company, who also sells non-donut shaped bean seats.

(Thanks, Andy, for the tip!)
