Felt like the chair was protecting us from some of the more insidious side effects of sitting down.

Conforms to your back while weight-sensitive recline adjusts automatically - but barely noticeably - with each movement.

Blends an industrial minimalist design with a slew of feel-good features.

A perfect score for seat comfort and backrest comfort, and we were impressed to note that its 'tri-panel backrest' also provided exceptional lumber support.

A very comfortable chair.

The Humanscale Diffrient World chair has produced a seat that's brimming with effortless ergonomic comfort all contained in a sleek design that adds a touch of modernity to a workspace.
