A 2010 deign by Antonio Citterio for Vitra. The Id concept chair comes in a wide variety of options. We particularly liked these examples due to the colour and condition of the light tan leather. The seat heiht, arm heaight angle of seat and lumbar support all adjustable.
We have three similar chairs, all in great used condition, at a significant reduction from the new price.
A study by the Institute for Biomechanics at ETH Zurich - one of the most renowned universities worldwide – showed that the ID Chair's scope of movement is fully utilised. EMG measurements (electromyography) confirmed that intuitive use of the weight-dependent forward tilt mechanism activates core muscles in the abdomen and back. This boosts the metabolism and stabilises the lumbar column. MRI/MRT measurements (magnetic resonance imaging) proved that the forward tilt function triggers movement in all segments of the lower spine. This relieves pressure and enhances the diffusion of nutrients to the intervertebral discs. These dynamic sitting features actively prevent health problems.
