Treston Ergo 35 Task Chair

Treston Ergo 35 high industrial task chair for raised workstations

The Treston Ergo 35 is a Finnish-designed high industrial task chair for assembly, packing, quality control and other technical work carried out close to the workpiece. Its broad seat-height range, adjustable seat angle and supportive backrest let the user move between upright and forward-leaning positions as the task changes. The chair comes with a foot ring and glides. This combination is well suited to elevated workstations: the foot ring gives the feet a clear resting point, while the glides provide a stable base when the user turns, reaches or changes position.

Made for work above standard desk height

The 580–850 mm seat-height range allows the Treston Ergo 35 to be used at raised assembly benches, packing tables and inspection points. It can also provide seated support in work areas where employees alternate between standing and sitting. Height adjustment helps align the user with the work surface and the task instead of forcing the body to adapt to a fixed chair height.

A high workstation chair must do more than raise the seat. When the feet no longer reach the floor comfortably, a suitable support point becomes important. The included foot ring gives the user a place to rest the feet and makes the elevated sitting position easier to maintain. The glides prevent free rolling and help the chair stay where it is placed, which is useful in close, precise work where unwanted movement can interrupt the task.

Support for forward-leaning precision work

Assembly and inspection often require the user to lean towards small parts, tools or measuring equipment. The Treston Ergo 35 uses a contact backrest mechanism that follows the working position and maintains support when the upper body moves forward. The seat tilt can be adjusted to support a more open working angle at the hips. Together with the height-adjustable backrest, this helps the chair adapt to different users and different stages of the job. The backrest is 460 mm high, providing useful support while leaving room to turn, bend and move the upper body.

Black fabric or black ESD fabric upholstery

Two upholstery options are listed for this product page: black fabric and ESD fabric. Fabric provides a soft textile surface. The choice allows the chair to be matched to the requirements of the workstation. Both listed upholstery variants are rated at 50,000 Martindale cycles. The Martindale figure provides a standard way to describe how well an upholstery material withstands repeated rubbing.

Adjustment that supports changing tasks

Industrial work rarely holds the body in one position all day. A user may sit upright while checking instructions, lean forward during assembly, turn to collect a part and then raise or lower the seat for the next task. The Treston Ergo 35 is designed around this kind of variation. Seat-height adjustment sets the main working level, seat tilt supports close work, and backrest-height adjustment helps place support where it is needed. These controls also make the chair easier to use in a shared production environment.

Foot ring and glides for elevated seating

The foot ring is one of the defining features of this high industrial task chair. It provides a consistent support point below the seat when the chair is adjusted beyond normal desk-chair height. The user can therefore keep the feet supported even when the seat is raised for work at a high bench. The glides complement the foot ring by keeping the chair stable on the floor. This matters when the operator applies light sideways force, reaches for a tool or leans towards the bench. The glides are intended to resist unintended rolling during the task.
