Takumi - backrest

The chair backrest has been designed with durability, ergonomics, and precise user adaptation in mind. It is made of durable, resistant, yet flexible upholstery, mounted on a polypropylene frame with 30% fiberglass added, ensuring high structural stability and even load distribution.

Underneath the upholstery of the Ergo Takumi chair's backrest, additional full-surface back support is provided in the form of a contoured, biomimetic structure with an ergonomic, mesh, woven shape. This element is made of light grey antibacterial TPE (thermoplastic elastomer), which enhances hygiene of use and improves the functional qualities of the backrest.

The upper part of the backrest is upholstered to a height of 135 mm, the sides to a width of 60 mm, and the lower part to a height of 40 mm. The entire structure is set within a frame that forms a characteristic 'window', through which the thermoplastic elastomer structure is visible, emphasizing the product's technological character.
The backrest width is 420 mm, widening to 475 mm at the bottom, and its height is 565 mm. The height adjustment – along with the contoured lumbar section – is performed using 4 detents over a range of 45 mm, allowing precise adaptation to the user's height and body build. The backrest tilt angle is adjustable in 6 positions from 85° to 125°.

The back of the chair's backrest is mounted on a durable polished aluminum structure. The screws attaching the backrest to the height adjustment mechanism and the lumbar part are aesthetically concealed under a plastic cover. The structural element consists of two polished aluminum arms, diverging downwards and connecting under the seat with the mechanism components and armrests, ensuring the integrity and rigidity of the entire structure.

The chair's backrest structure has the function of following the natural movement of the user's back during left and right leans, providing dynamic, multi-planar support and high working comfort.

The possibility of adjusting the backrest height allows it to be adapted to the user's height, providing proper support for the entire spine. The tilt adjustment allows changing position during work, which improves circulation and reduces muscle fatigue.
