Back in black. Don’t let the Hatejäll minimalist Eighties matt-black less-is-more, form-is-function design put you off – this is a deeply comfortable chair sold by IKEA.

The gently curved lines accentuated by sewn details are kind to your body and pleasant to look at. Also, there’s a tilt and height-adjusting mechanism that’s built to outlast years of the ups and downs running any small business.
