M18-M148 - Ergonomics in a new form!

In this high-tech office chair you sit comfortably and feel well and fit even after a long working day. The swivel chair M18-M148 combines innovative design with maximum individual adjustment options. This allows you to adjust not only the seat height, but also the angle and height of the headrest as well as the height of the armrests individually. With the lockable synchro mechanism, the angle and resistance of the breathable mesh backrest can also be adjusted. Particularly comfortable and firmly upholstered is, in addition to the ergonomically pre-shaped fabric-covered seat, the height-adjustable lumbar support. The modern look is impressively rounded off by the solid base made of polished aluminium.

  • Extra wide headrest, adjustable in height and angle
  • High, breathable mesh covered backrest
  • Pleasantly thick-padded lumbar support, height-adjustable up to 5.5 cm
  • Height-adjustable armrests with softpad covering
  • Wide, contoured seat: luxuriant cover with rounded seat front
  • Comfortable synchronous mechanism - The mechanism or rather the resistance when leaning back can be individually adjusted via a rotary knob below the seat and can be locked in an upright position.
  • Stable, high-quality, polished aluminium base
  • Fitted with weight-activated multi-purpose castors. As such, the user has complete freedom of movement while seated. Upon standing up, the safety braking mechanism hinders unwanted movement of the office chair. The castors are unlocked when pressure is placed back on the chair.
  • This chair complies with DIN EN 1335 Part 1-2 & EN1021-2

To keep your new office chair beautiful for a long time, it should be cleaned regularly. Here are a few practical tips on how to care for your office chair and how to properly treat and clean leather, synthetic / faux leather and fabric.
