Description

Ergonomic mesh back office chair with a synchronised tilt that moves seat and back together, backed by anti-shock and a weight tensioner. Height adjustable lumbar support, multi adjustable removable arms, an optional pivoting headrest and 21 upholstery colours, rated for 8 hour use with a 120kg capacity and a 5 year mechanical guarantee.

A tilt that moves with you

Recline in the Prism and the seat and backrest move together in a synchronised ratio, keeping your feet grounded and your eyes level rather than pitching you backwards. The weight tensioner dials the resistance to your build, so a lighter user is not fighting the mechanism and a heavier one is not falling through it, and the anti-shock feature stops the backrest springing forward when you lean back and let go. It is the difference between a chair that reclines and a chair that reclines well.

Set to the person, not the average

As befits a high back ergonomic mesh office chair, the backrest breathes through warm afternoons and carries a height adjustable lumbar support, so the firmest pressure lands exactly where your lower back wants it. Gas height adjustment runs from 47.5cm to 57.5cm, a usefully tall range for higher desks. The armrests adjust for height between 65.5cm and 71.5cm and for angle, with pads that slide to suit different sitting positions, and they remove entirely if you prefer. An optional headrest, height adjustable and pivoting, looks after the neck through long calls and late finishes.

Upholstery to suit the office

Black fabric from stock keeps it classic; 20 bespoke colourways make it yours. The hard-wearing Rivet collection covers muted industrial shades, Quest is made with yarn from recycled plastic bottles, and brighter options run from Bergamot Cherry to Maringa Teal.

Right for your business

The Prism suits anyone equipping desks for genuine all-day use: growing teams, home workers keeping office hours, and businesses that would rather buy one well-adjusted chair than replace three cheap ones, helped along by the 5 year mechanical guarantee. One clear price, full specifications on the page, and no sales calls required.

Seat and height adjustment

  • 49cm wide seat with a 49cm to 54cm depth. A comfortable sitting area with room for longer legs to be properly supported.

  • Gas seat height adjustment, 47.5cm to 57.5cm. A tall-reaching range that suits higher desks and taller users.

Backrest and posture support

  • High mesh back, 43cm wide, 58cm to 76cm high. Breathable support up the full length of the spine.

  • Height adjustable lumbar support. Position the lower back support exactly where you need it for long, comfortable sittings.

  • Synchronised tilt with anti-shock. Seat and back recline together naturally, and the backrest never springs forward at you.

  • Weight tensioner. Adjustable recline resistance to match the person in the seat.

Arms and headrest

  • Multi adjustable removable arms, 65.5cm to 71.5cm. Height, angle and sliding pads keep arms supported in a natural posture, or remove them entirely.

  • Optional height adjustable, pivoting headrest. Proper neck support for reclined working; choose the chair with or without.

Size, capacity and usage

  • 67cm wide, 65cm deep footprint. Full ergonomic support that still fits a normal workstation.

  • 120kg maximum weight capacity. A sturdy rating comfortably above the budget task chair.

  • Recommended for 8 hour use. Built and rated for the complete working day.

Guarantee

  • 5 year guarantee on mechanical components, 2 years on fabric and foam. Long cover on the synchro mechanism that makes the chair worth having.

    Comfortable and properly adjustable

    Ergonomic mesh chair with arms that move and a back that actually supports. Set it up in ten minutes and it has been right ever since. Good value.
