Takumi - seat

In Ergo Takumi - the seat is made of high-quality cast polyurethane foam using high-temperature molding technology. The foam used, with a density of 55 kg/m³, has a thickness of 57.5 mm. The polyurethane foaming process in molds ensures a uniform, compact structure without empty spaces, which translates into high durability, resistance to deformation, and long-term retention of performance parameters. The foam does not require the use of glue or formaldehyde, making it safe for health and environmentally friendly.

The front edge of the seat has been ergonomically rounded, which reduces pressure on the thigh muscles and limits the risk of lower limb numbness when maintaining a forward-leaning position, e.g., during handwriting. The entire seat is covered with durable and wear-resistant upholstery.  The underside of the seat is a cover made of polypropylene with an addition of 25% fiberglass, 3.1 mm thick, which effectively prevents deformation and strengthens the structure.

The seat width is 490 mm, and the depth is 500 mm. Seat height adjustment is performed using the first aluminum handle (dim. 73x23 mm), located under the seat on the left side. This adjustment allows you to place your feet stably on the floor, while maintaining an angle of approximately 90° at the knees. This is the basis of an ergonomic position that supports proper circulation and reduces strain on the lower back. It also prevents nerve compression, muscle tension, and numbness in the legs and buttocks.

Depth adjustment is available in the range of 40 mm in the Ergo Takumi model. The mechanism is operated by a handle (dim. 45x15 mm), made of polyamide with an addition of 30% fiberglass, located under the seat on the right side of the seated person, which allows for intuitive and ergonomic adjustment to the user. This adjustment allows the chair to be adapted to the user's thigh length. The appropriate distance between the seat edge and the knees prevents pressure on blood vessels and improves sitting comfort.

Additionally, the seat offers the possibility of forward tilt adjustment within a range of 3°, supporting a more dynamic, active sitting position.
