Two seating spaces I didn't get a chance to sit in: some pointy mineral deposits by Aranda/Lasch in collaboration with Island Planning Corporation, and raumlaborberlin's Kitchen Monument, which played host to a programme of talks and exchanges.
The Giardini was dotted with interesting spaces to congregate, some more inviting than others. Modern Primitives by Arada/Lasch and Island Planning Corporation, are made of "loosely dispersed mineral furnishings, fabricated in foam with a hard Line-X finish." They are meant to be sat on, leaned on, held in your arms. I did see some people tentatively sitting down, but I forgot to come back and try them myself.
Nearby, raulaborberlin's Kitchen Monument provided an mobile space for collective interactions. This looked familiar, and I just realized it's the same inflatable space that's been floating around London this summer.
