I'm amused by the way everyone's drooling over this as if it's new — it actually dates back to the early 1980s(!); see http://www.opsvik.no/index.asp?page… for some notes from the designer (plus animations).

Having had a pair of Gravity(s) at home for over ten years, can confirm that they are extremely (a) distinctive, (b) comfortable, and (c) expensive. [BTW: they're even MORE expensive if you get them covered in fancy non-Stokke fabrics, such as Alcantara ...] [OTOH, FWIW: eBay often has good used examples at less scary prices.]

w.r.t. specific comments above:

* iceberg, r55741, auger282, re impaling people: I'm afraid not :-) [in any case, I'm with smirkinghammer on that]

* barkingart, Grifter, re cats: on the other hand, I'm afraid that's something you do need to watch out for

* auger282, deusdiabolus, re space: yep, they do take up quite a bit of room — probably 6' front-to-back for their full range of positions

* HitScan, Penchurn, re stability: the wooden legs provide some degree of flex/give, which can be somewhat disconcerting at first, but they're actually incredibly stable — the design is all about balance — though things can go slightly roller-coaster if the cat jumps up onto you in the reclined positions!

* msg007: good luck!
