FAQs: Secondary School Seating Advice
Q: Is "Size 5" correct for Year 7 through Year 9?
A: Size 5 (430mm seat height) is the ergonomic standard for students aged 11 to 14 years. It ensures that secondary students can sit with a flat-footed stance, which is essential for maintaining correct sitting habits during senior school.
Q: How does the "Anti-Tilt" feature improve classroom management?
A: Secondary students are often 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 colour for a busy senior school?
A: Yes. Dark Grey provides a professional aesthetic that reduces visual noise. The polypropylene is completely non-porous and resistant to ink and common school chemicals, allowing for instant sanitisation with standard cleaners.
Q: Can adults safely sit on these Size 5 chairs?
A: Yes. Despite being dimensioned for students, the high-strength powder-coated steel frame is rated for a massive 125kg. This makes it perfectly safe for teaching staff to sit briefly during group work 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 secondary 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 4.3kg 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 secondary school with a definitive long-term seating solution.
Q: Why purchase from Cobolt Furniture?
A: With 50 years of expertise, we are a trusted partner to UK education. We offer Free UK Mainland Delivery, expert product knowledge, and furniture built specifically for the demands of the modern curriculum.
