Carismo - seat

The ergonomically contoured seat is made of high-quality cast polyurethane foam (polyurethane foaming technology in molds) with a density of 55 kg/m³ and a thickness of 69 mm, covered with durable and resistant upholstery. The foam molding process at high temperature and the use of flexible material guarantee a uniform structure without empty spaces, which translates into high durability and resistance to deformation. The foam does not require the use of glue or formaldehyde, making it safe for health and environmentally friendly. The underside of the seat is a cover made of polypropylene with 25% fiberglass, with a thickness of 3.1 mm, making it resistant to deformation.

The seat has a rounded front edge to reduce pressure on the thigh muscles and prevent numbness in the lower limbs when maintaining a forward-leaning body position (e.g., during manual writing).

The width of the seat is 510 mm, with armrests 700 mm, and the depth is 510 mm. The seat height adjustment range of 500-600 mm is performed using a lever located just below the seat on the right side of the person sitting. This adjustment allows the feet to be placed firmly on the floor, while maintaining a knee angle of approximately 90°. 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.

The seat also has a depth adjustment of 45 mm, using a lever located under the seat on the left side of the person sitting, which allows for easy and ergonomic adjustment of the chair to the user. This adjustment allows the chair to be adapted to the user's thigh length. The appropriate distance between the edge of the seat and the knees prevents compression of blood vessels and improves sitting comfort. The seat combines excellent functionality with an ergonomic form, ensuring high sitting comfort even during long-term work.
