Product Details

A drum-back construction that behaves like neither a mesh chair nor an upholstered one – Drumback stretches mesh over a polypropylene back shell rather than across an open frame. The result combines the airflow of a mesh back with the structural stability of a solid one, in a single moulded form.

Rated for sustained, intensive use – On the Standard specification, Drumback is rated for 24-hour use. Both specifications are rated to 110 kg. Its automatic synchro-mechanism responds to bodyweight without manual tension setting, with an additional fine-tuning control for those who want to override it.

Key Highlights:

  • Rated for 24-hour use on the Standard specification

  • Automatic synchro-mechanism with fine-tuning control – responds to your weight, then lets you adjust further

  • Height-adjustable backrest, 8 positions – standard, not an option

  • Sliding seat depth, 6 positions – standard, not an option

  • 3-position tilt limiter with free-flow recline

  • Integrated function buttons – controls sit within the mechanism housing rather than protruding beneath the seat

Two adjustments that are usually extras, included as standard – backrest height and seat depth are both adjustable out of the box, which is unusual at this specification level.

  • Automatic weight-responsive recline: The mechanism sets its own resistance from your bodyweight, so the chair works correctly without setup

  • Additional fine-tuning control: Override the automatic setting if you prefer a firmer or looser recline

  • 8-position height-adjustable backrest: Raises and lowers through eight positions

  • 6-position sliding seat: Set seat depth to your femur length

  • 3-position tilt limiter: Cap how far the chair reclines, or leave it free-flowing

  • Mesh over a moulded back shell: Airflow through the back without the frame flex of an open mesh panel
