If you’re looking for unique seating options, or anything else modern and fresh, try visiting the MoMA Store.
For lighting, the Standing Blue Lamp designed by Isamu Noguchi is gorgeous, and who can resist the Wise Ol’ Owl Mobile, inspired by 1960’s Japanese and Danish design designed by Helene Ige. For seating, how about the very cool Ripple Chair from Ron Arad (looks like a giant bow), or the Supernatural from Ross Lovegrove, available in green (shown) or white. The Supernatural also happens to be somewhat of an affordable find at $180.-USD.
