Summary

A Sedus swivel chair whose suspended backrest follows you and reclines up to 45°.

Best for

  • People who like a backrest that moves with them as they shift.
  • Reclining breaks; the back opens to 45°, depending on body weight.
  • Offices buying through a dealer, where Sedus configures each chair.

Good to check first

  • The standard rating is 120 kg (about 265 lb), so check it against your weight.
  • 3D armrests, lumbar support and a neck support are options; pick them when you configure.
  • Choose the 450 mm seat if you want more depth than the standard 420 mm.
  • Sedus sells it through dealers, so ask for a quote with your chosen options.

The trade-off

A distinctive moving backrest and deep recline, sold by quote rather than at a list price.

Value check

What Sedus highlights

  • Dorsokinetic backrest

    The backrest is suspended so it can follow your movements. Sedus first developed this idea for its Paris chair in 1987.

  • Similar mechanism

    Seat and back move together at a fixed ratio, and the tension is set to your weight. Sedus calls this its Similar mechanism.

  • 45° recline

    The back opens up to 45°, depending on body weight. Sedus pairs this wide angle with the moving backrest.

  • Options to configure

    3D armrests with soft-touch, leather or gel pads, a height-adjustable lumbar support and a neck support are available. The back comes as a membrane or cushioned version.

As described by Sedus on its official pages; not a Chairpedia assessment.
