Not something we have seen in the UK, but for readers in North America, the Gus Modern Spencer armchair.
Packing that late 50s/early 60s Knoll-style look, the Spencer, which is available in various colours, has a blind-tufted seat and back cushion, plus a stainless steel inset base for a seat that's likely to be as comfortable as it is stylish.
Available from Allmodern in the US, prices start at $1,155.
