ID Trim L

Antonio Citterio, 2010/2021

With its compact padding, the backrest of ID Trim conveys a sense of classic elegance and quality craftsmanship. The sandwich construction with integrated lumbar support provides the comfort of an upholstered backrest while being almost as slim as a mesh backrest – presenting an alternative to both of these construction types. ID Trim L is an excellent choice for the executive office due to its high backrest, which offers extra relief from tension in the head and neck.

The ID Chair Concept offers countless customisation options to suit individual users. Thanks to different variations of the FlowMotion mechanism or the self-adjusting AutoMotion synchronised mechanism – along with a selection of backrests, armrests, seats and bases, and a broad array of colours and fabrics – every user and company can find the perfect ID Chair, whether for an open-plan setting, individual or team offices, conference areas or management offices. Despite the many possible variations, it always remains essentially the same chair in look and construction, with benefits for companies in terms of aesthetics, maintenance and service – and some models are 100% recyclable. A study by the Institute for Biomechanics at ETH Zurich – one of the most renowned universities worldwide – showed that the ID Chair's range 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. It also relieves pressure and enhances the diffusion of nutrients to the intervertebral discs. These dynamic sitting features actively prevent health problems. The pleasantly soft seat options, the multi-adjustable armrests and the supportive backrests provide a high degree of comfort. Thanks to the use of V-Foam – developed by Vitra in collaboration with BASF as the world's first recyclable polyurethane foam – the ID Chair is now even more sustainable: the upholstery of the seat cushion made of 100% recyclable V-Foam enables ID Chair configurations that are 100% recyclable. The ID Chair Concept consists of the models ID Cloud, ID Air, ID Mesh, ID Soft, ID Soft L, ID Trim and ID Trim L, each with a different backrest type. For a unified aesthetic, the ID Visitor family offers a range of matching meeting and visitor chairs.
