A superb impact chair is currently available in eBay for a price that doesn't break the bank – the Robin Day space age 4-4000 chair for Hille.
I know it has impact because I have one in my home already, although it does look a little different than the above, due to this one being re-upholstered, but with some style I have to say. The recliner chair was made by Day for Hille in the 70s as part of a 'Living Theme' aimed at a younger crowd and sold in Habitat, offering up a podium for different seating angles and foam cushions for comfort.
Time has led to a little 'yellowing' of the chair (like ours too), but it's still an amazing seat that's been out of production for years. £399 gets it on a 'Buy It Now' or you can make an offer.
