Office chairs

Ergonomic office chairs are a relevant market for high-quality molded foams — users spend 6-10 daily hours sitting, making comfort and postural support critical product components. Typical construction: seat in molded HR foam with density 45-55 kg/m³ for combination of immediate comfort and long-term durability, backrest in HR foam of lower density (30-40 kg/m³) for ventilation and flex, armrests in integral skin PU (paintable coating, firm touch with impact absorption). Premium models incorporate zoned foams (different densities in lumbar, shoulder, hip regions), viscoelastic foam in the seat (pressure distribution), and combinations with technological mesh (tensioned mesh as alternative to foam in specific segments). Competitive market globally, with reference brands (Herman Miller, Steelcase, Haworth, Flexform) operating in premium segment and Chinese brands (Sihoo, Hbada, Naouyo) dominating world volume. In Brazil, brands like Flexform, Frisokar, Cavaletti compete in different segments.
