We've actually covered the reissue of this design before, but on right ebay right now is a pair of Rodolfo Bonetto Melaina easy chairs from the original 1970s issue, complete with a very 1970s colour scheme.
The original design by Bonetto was for Driade, with the chairs packing that distinctly 'Space 1999' look of the era, made of fibreglass and theoretically good for indoor use or out – although judging by the minor damage to these pieces, it might be wise to keep them away from the elements.
The reissues cost over £800 each, whereas these two chairs are £500 or 'best offer' for the pair. If you want more than two, the seller claims to have 'several' in stock, should you have a large family or social circle.
