Description

High mesh back task operator office chair built for demanding contract use. A triple lever mechanism adjusts seat and backrest angle independently, with a seat slide, ratchet height adjustable backrest and height adjustable lumbar support. Breathable airmesh seat, removable padded arms, a 125kg capacity and 21 upholstery colours.

Three levers, every angle yours

The Portland III's triple lever independent mechanism splits the adjustments most chairs lump together. One lever sets the seat angle, another sets the backrest angle, and the third handles seat height, so you can tip the seat forward for focused work while keeping the back exactly where your spine likes it. A seat slide moves the depth between 48cm and 53cm for longer or shorter legs, and a weight tilt tension control matches the recline resistance to the person in the chair. It is the sort of adjustability usually reserved for chairs at twice the price.

Support that lands where it should

The high contoured mesh backrest ratchets between 50cm and 58cm, so the whole back panel rises to meet your spine rather than hoping one height fits all. Within it, a height adjustable lumbar support fine-tunes where the firmest pressure sits, and the open mesh keeps air moving across your back through the day. Below, the high density soft moulded seat is finished in breathable airmesh fabric, pairing lasting shape with a surface that stays cool.

Contract-grade build, 21 colours

At 20kg with a 125kg maximum capacity, this high mesh back task operator chair is built for the demanding contract environment: shared desks, long shifts and users who do not baby their chairs, all backed by a 5 year mechanical guarantee. Take it in black airmesh from stock, or specify one of 20 bespoke colourways including the hard-wearing Rivet collection and Quest, made with yarn from recycled plastic bottles.

Right for your business

The Portland III suits offices fitting out for the long term: teams standardising on one chair for every height and build, busy studios, and anyone whose day genuinely runs the full 8 hours in the seat. One clear price, full specifications on the page, and no sales calls required.

Seat and height adjustment

  • 53cm wide high density moulded seat in breathable airmesh. Lasting shape from moulded foam, with a cool-touch breathable finish.

  • Gas seat height adjustment, 47cm to 58cm. A tall-reaching range that suits higher desks and taller users.

  • Seat slide with a 48cm to 53cm depth range. Full thigh support for longer legs without pressure behind the knees.

Backrest and posture support

  • High contoured mesh back, 47cm wide. Breathable, flexible support that keeps your back cool through the day.

  • Ratchet height adjustment, 50cm to 58cm. Raise the whole backrest so support meets your spine where it should.

  • Height adjustable lumbar support. Fine-tune the lower back pressure to suit your posture.

  • Independent seat and backrest angle adjustment. Set each angle separately via the triple lever mechanism, with weight tilt tension control.

Armrests

  • Height adjustable padded arms, 68.5cm to 76cm. Relaxed shoulders and supported elbows at desk height, and fully removable if preferred.

Size, capacity and usage

  • 65cm wide, 65cm deep, 99cm tall. A full-size task chair footprint that still suits a standard workstation.

  • 125kg maximum weight capacity. A contract-grade rating well above the everyday task chair.

  • Recommended for 8 hour use. Rated for the complete working day, every day.

  • 20kg build weight. The heft of a chair made for demanding contract environments.

Guarantee

  • 5 year guarantee on mechanical components, 1 year on fabric and foam. Long cover on the triple lever mechanism at the heart of the chair.

Our computer and task chairs range holds the full Portland family, with plenty more mesh office chairs to compare.

    High back version is better

    We have both the medium and the high back and the high back is worth the extra for anyone tall. Mesh is comfortable. Arms are fixed height on ours.
