Posture chair with leatherplus upholstery

The BOSS B306 is a black task chair upholstered in LeatherPlus, a leather and polyurethane blend designed for softness and durability. It features a thick padded seat with a waterfall-edge design and a cushioned backrest with built-in lumbar support. A pneumatic gas lift provides seat height adjustment, while the back depth can also be customised. The chair sits on a 25 inch nylon five-star base with hooded double-wheel casters for mobility.

Height-adjustable arms for personalised support

The T-style armrests adjust vertically to suit different users and desk heights, helping to support the forearms during long sessions. Buyers who need arms that also pivot, slide forward or adjust in width will not find those functions here. The mechanism lacks infinite tilt lock, knee tilt and tilt tension controls, so users who want a fully articulating recline with resistance settings should look elsewhere.

25 inch nylon base with hooded casters

The five-star base measures 25 inches across and is moulded from nylon for stability and smooth rolling on the supplied hooded double-wheel casters. This specification determines whether the chair fits the intended floor space and moves freely on the surface where it will be used.

Questions about this item

What comes in the box with the B306 chair and is any assembly hardware sold separately?

The box contains the chair frame, seat, backrest, adjustable arms, 25 inch nylon base, hooded double wheel casters and pneumatic gas lift; all required assembly hardware is included.

The specs list adjustable arms, pneumatic gas lift and a 25 inch base — how do I decide which configuration suits my desk height?

Choose this single configuration if your desk height matches the gas lift range; the adjustable arms and seat height let you fine-tune fit without needing a different model.

How does the 25 inch nylon base with hooded double wheel casters perform on carpet versus hard floors?

The 25 inch nylon base gives stable support while the hooded double wheel casters roll smoothly on both low-pile carpet and hard flooring without snagging.
