If you want to be a criminal mastermind, you need three things – a cunning plan, a cat and a big chair to swing around in. Something like this B&B Italia Metropolitan Armchair.
It’s a fairly new design (2003) by Jeffrey Bernett, but with a flowing look rooted firmly in the 1960s. In terms of structure, the chair is made of tubular steel with Bayfit flexible cold shaped polyurethane foam for comfort and a choice of upholstery for the finish. The base is either spokes or disc, whatever you prefer.
Available online, you can pick one up for £1,366 – no doubt paying for itself after you’ve held the world to ransom.
