We have featured the more commonly seen Hille 4-4000 armchair by the same designer in the past, but not the Obo, which is a far more quirky (and we think rarer) piece.
It has a frame of lightweight polypropylene construction and still has its original bold upholstery. Great for a seat, great for design, great for any interior inspired by the space age era. £220 is the 'Buy It Now' price, but you can put in a cheaper offer if you like. many more images on the listing.
