• Postural ergonomics and prolonged comfort: The monobloc design with flexible rear reinforcement follows the student’s movements, reducing muscle fatigue during classroom hours.
• Active prevention of injuries and impacts: The fully rounded edges and the non-slip texture of the polypropylene shell eliminate sharp edges, minimizing the risk of accidental trauma.
• Structural resistance and record-breaking stability: The chemical cycle with nanoceramics and anti-corrosion microcrystalline bath increases the adhesion of the epoxy-polyester paint by 300%, protecting the frame from rust, scratches, and nicks.
• Logistics space optimization: The ability to be stacked up to 8 chairs allows school staff to quickly clear classroom floors, facilitating daily routine sanitization cycles.
• Total floor grip and protection: Non-slip plastic feet mounted on each leg dampen dragging noises and prevent the formation of scratches or streaks on school floors.
• Quick and light movement: The transport handle integrated into the upper part of the backrest allows teachers and students to lift and reposition the chair with one hand and without effort.
• Ready to use without assembly costs: The chair is delivered fully assembled and factory-tested, eliminating downtime and costs related to manual assembly of components on site.

This size 5 school chair finds its optimal application in furnishing classrooms, computer labs, multimedia rooms, and canteens within primary schools, secondary schools, youth training centers, high schools, and advanced study rooms. Thanks to a seat height calibrated at 430 mm and general dimensions of 49x49x78.5 cm, it represents the perfect tool to meet the needs of public and private school institutions that require robust monocolor seating, compliant with ergonomics regulations and ISO certified to ensure a long life under heavy continuous use conditions.

The h979_44 model is the correct choice when the furnishing plan for schools requires a size 5 chair (430 mm seat) that is robust, hygienic, and equipped with a steel frame treated with nanoceramics to resist impact and continuous wear. It proves far preferable to common cheap plastic chairs or those with non-passivated metal structures, as the increased thickness of the steel tube (up to 2 mm in the cantilever version) combined with the polypropylene shell with non-slip texture ensures anti-tip stability and 300% superior corrosion resistance. Choosing this seat means investing in safe and ISO 9001, 14001, and 14006 certified school furniture, designed with respect for the environment to guarantee a long useful life in school departments.

What dimensional parameters define the size 5 of this school chair?

Size 5 identifies a chair with a seat height from the ground equal exactly to 430 mm. The total geometric overall dimensions of the chair provide a width of 49 cm, a depth of 49 cm, and a maximum total height from the ground equal to 78.5 cm, dimensions calibrated for use by primary and secondary school students.

What does the special treatment applied to the metal structure of this model consist of?

The metal structure, made of Ø 20 mm steel tube with a thickness of 1.5 mm for the 4-leg version, is subjected to an advanced industrial finish and protection cycle. This process includes an epoxy-polyester electrostatic powder coating preceded by a degreasing phase and the application of nanoceramics via an anti-corrosion microcrystalline bath and a passivation process. This treatment improves paint adhesion and resistance by 300% compared to traditional methods, protecting the chair from scratches and rust.

What ergonomic and safety measures are integrated into the polypropylene shell?

The monobloc polypropylene shell is designed according to strict school ergonomics criteria. It features a flexible rear reinforcement that follows the user’s movements, fully rounded edges to eliminate sharp contact points, and a non-slip surface texture that ensures seat stability. Additionally, the upper part of the backrest integrates a shaped handle that allows the chair to be grabbed and moved quickly and safely with one hand, supporting stackability up to 8 pieces.
