Vitra MedaPal

Combining intelligent technology with exceptional comfort, the MedaPal office swivel chair exudes an air of lightness with its simple, user-friendly design. Constructed from a small number of high-quality parts, it makes an economical, ecological and long-lasting addition to any office.


The innovative polyamide back frame, precisely moulded in a single piece and covered with a netweave sling, provides targeted lumbar support. At the same time, the backrest offers flexibility and freedom of movement. A slight indentation in the contoured seat keeps the pelvis upright. All these characteristics are combined with the synchronised mechanism to create instant comfort, and intuitive controls prevent users from making incorrect adjustments.

MedaPal offers all the necessary functions for ergonomic comfort in a sustainable quality, which makes it an extremely economical office swivel chair. Easy maintenance is facilitated by a small number of parts while the backrest, seat cushion and armrests are simple to replace.


MedaPal was the very first office swivel chair to be awarded the ‚Blue Angel‘ seal for low-emission upholstered furniture. In addition, it has been certified with the ‚GREENGUARD Indoor Air Quality Certified Label‘.

ID Chair Concept

The ID Chair Concept offers countless customisation options to suit individual users. The FlowMotion and the ProMatic mechanisms with their multiple functions, a variety of backrests, armrests and bases as well as a wide range of colours and upholstery covers allow each user and each company to create ‘their’ own ID Chair – be it for open-plan workspaces, 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.

A study by the Institute for Biomechanics at ETH Zurich – one of the world’s leading universities – demonstrated the comprehensive benefits of the ID Chair’s range of movement. EMG measurements confirmed that the intuitive use of the weight-dependent forward tilt results in greater activity of the stomach and back muscles. This boosts the metabolism and stabilises the lumbar column. MRI measurements 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 vertebral discs. These dynamic sitting features actively prevent health problems.

The chair is available with the “ProMatic” chair mechanism as well as with the “FlowMotion” mechanism. “ProMatic” automatically adapts to the weight of the user. The user therefore only has to set the seat height. ProMatic is ideal for touchdown workstations and for conference and meeting areas of all kinds. The Flow-Motion mechanism and its many functions can be set to the exact requirements of the respective user.

The soft seat and supportive backrest ensure great comfort. With the optional integration of Clima Seat fleece, the seat maintains pleasant thermal conditions for up to eight times longer than conventional seat surfaces.

The ID Chair Concept consists of the models ID Air, ID Mesh, ID Soft, ID Trim, ID Trim L and ID Trim Cap, each with a different backrest.

Vitra Tip Ton

Tip Ton is a tilting chair fully maid of plastic. From the normal position, users can tilt the chair forwards by shifting their weight. This forward tilt sitting position straightens the pelvis and spine. Tip Ton is made entirely of polypropylene. This ensures the longevity of the chair and makes it 100 per cent recyclable. Tip Ton is stackable up to four chairs and comes in eight different colours.

In 2010, the Swiss Federal Institute of Technology Zurich (ETH) conducted a study on the degree to which pressure to the spine can be relieved by alternating sitting positions. The results show that shifting between the various sitting positions – i.e. between upright, a reclining and a forward-tilting position – sets all segments of the tower spine in motion. This both relieves pressure on and inccreases the nutrient supply to the intervertebral discs. Tip Ton’s special geometry encourages the user to alternate between the above sitting positions. Moreover, whereas in the past the health benefits of relieving the intervertebral discs where reserved for office chairs, Tip Ton Allows user to profit from these benefits in an array of different environments. 30 Jan 2012 Tip_Ton_00012692 Tip Ton 1 Tip Ton 2 Tip Ton 4

Vitra Physix

Physix, developed with the shared engineering expertise of Alberto Meda and Vitra, is the all-round chair for today’s modern office. Its light, expressive, and high-quality look and easy adjustment options make it ideal for the use in a variety of different work and meeting situations. At the time, Physix meet the most discrening demands in termsof both comfort and ergonomics thanks to its sophisticated design and materials.

Physix5

The structure of Physix is based on the idea of creating a continuous seat shell by stretching a single textile panel between two side members. With its design, the chair assumes its place in a long line of iconic chairs while taking the typology to yet another level.

Physix4Using state-of-the-art materials and production technology, Alberto Meda orchestrates an interplay of three elements to create a new dynamic sitting experience: a flexible frame construction, an elastic knit cover and a stabilising mechanism.

Together these three characteristics form an ingenious construction that explores new possibilities of dynamic sitting through the interaction of flexible and rigid elements.

The aim behind the structural design of AC 4 was to discreetly integrate the functional elements required for optimal comfort. Up until now, the design of office chairs has emphasised either their aesthetic appearance or their functional features. By contrast, the integration of ergonomic features in AC 4 is so subtle that its sophisticated structural components remain concealed. It achieves a balance between the most advanced ergonomic functions and an unobtrusive appearance: the innovative technical features of AC 4 are neither put on display, nor are they hidden beneath foam padding. AC 4 is an emblematic object with an elegant appearance and uncompromising functionality, ideally suited for refined offices and conference spaces.

AC 4 is available as an office swivel chair and in the version AC 4 Conference for meeting venues.
