Chair Planet by Sven Ivar Dysthe. Manufacturer: Variér Furniture

Some seriously 60s looks and that's no coincidence - the Planet chair by Sven Ivar Dysthe was designed back in 1965. Designed as an elegant and functional armchair, it rotates as you'd expect, but it has something more - a patented mechanism that allows you to tilt the seat forwards and backwards. Complete freedom if you like.
