Product Overview: Size 4 Charcoal Anti-Tilt Senior Primary Seating
The Cobolt Size 4 Chair provides a durable, ergonomic foundation for students transitioning toward secondary education. Dispatched with Free UK Mainland Delivery, it is engineered to survive the high-frequency cleaning and heavy daily use required in Year 5 and Year 6 classrooms.
The Cobolt Advantage
- Fifteen-Year Financial Shield: Our extensive structural warranty provides unparalleled budget protection, ensuring your furniture remains a one-time capital investment for over a decade.
- Preventative Safety Design: The specialized anti-tilt legs act as a mechanical safeguard, shifting the balance point to discourage "chair swinging" habits among older students.
- Low-Maintenance Aesthetic: The non-porous charcoal shell resists staining and allows staff to maintain clinical standards with a simple wipe-down procedure.
Junior Posture & Responsibility
- Upper Primary Ergonomics: Adhering to Size 4 EN1729 standards, the 380mm seat height ensures students maintain a healthy lumbar position while keeping feet firmly planted.
- Eco-Responsible Lifecycle: Constructed from 100% recyclable polypropylene and steel, this chair supports your institution's carbon reduction targets.
- Enhanced Blood Flow: The downward-curved front edge removes pressure points behind the knees, preventing restlessness during tabletop learning sessions.

FAQs: Senior Primary Classroom Seating Solutions
Q: Is a "Size 4" chair correct for my Year 5 and Year 6 students?
A: Size 4 (380mm seat height) is the ergonomic standard for children aged 8 to 11 years. It ensures that senior primary students can sit with a flat-footed stance, which is essential for maintaining correct sitting habits during the final years of Key Stage 2.
Q: How does the "Anti-Tilt" feature improve classroom management?
A: Older primary students are often more active and prone to rocking on their chairs. The angled rear frame shifts the leverage point, making it mechanically difficult for the chair to tip backwards. This proactively prevents accidents and related focus disruptions.
Q: Is Dark Grey a practical choice for a primary school?
A: Yes. Dark Grey provides a sophisticated aesthetic that reduces visual overstimulation. The polypropylene is completely non-porous and resistant to ink and common school chemicals, allowing for instant sanitisation with standard anti-bacterial cleaners.
Q: What is the maximum weight capacity for these Size 4 chairs?
A: Despite being dimensioned for junior students, the high-strength powder-coated steel frame is rated for a massive 125kg. This ensures it is robust enough for occasional teacher use or evening community hires without structural risk.
Q: Are the seats tamper-proof to prevent interference?
A: Absolutely. We use industrial-grade tamperproof fasteners to secure the shell to the grey steel legs. This ensures students cannot loosen the fixings and that the chairs remain a permanent, safe asset in your school.
Q: Does this chair comply with fire and safety regulations?
A: Yes, it is fully compliant with BS EN1729 Parts 1 & 2, which are the specific standards for UK school furniture regarding ergonomics, strength, and structural durability.
Q: How easy are these chairs for cleaning staff to manage?
A: These chairs are designed for vertical stacking, allowing cleaning staff to clear floor space efficiently after the school day ends. Their lightweight 3.5kg build makes them easy to move.
Q: What does the 15-year warranty cover?
A: Our 15-year guarantee covers any structural failure of the welded steel frame and any manufacturing defects in the polypropylene shell. It provides your primary school with a definitive long-term seating solution.
Q: Why purchase from Cobolt Furniture?
A: We are a UK-based manufacturer with over 50 years of experience supplying schools. We provide Free UK Mainland Delivery, expert product knowledge, and furniture built specifically for the demands of the UK primary curriculum.
