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.
Certified for sustained, intensive use – On the Standard specification, Drumback carries BS 5459-2, the British Standard covering severe heavy-duty and 24-hour use seating. Both specifications carry a GS safety certificate 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:
BS 5459-2 certified on the Standard specification – the British Standard for severe heavy-duty and 24-hour use
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 and covers the two dimensions most responsible for a poor postural fit.
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: Move the lumbar contact point up or down to meet your spine
6-position sliding seat: Set seat depth to your femur length and relieve pressure behind the knee
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

Why it matters
Even a well-engineered chair won't help if it's set up incorrectly — you'll carry the same aches into a new chair. This guide covers the small, high-impact adjustments that fix the cause, not the symptom, so your chair delivers the comfort and support it's built for.
How you receive it
Place any order and we'll email your download link as soon as your order is confirmed. Open it on your phone, tablet or laptop and follow the steps as you set up your chair.
