FAQs: Senior Primary Classroom Seating Advice

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, essential for maintaining healthy sitting habits during the final stages of Key Stage 2.

Q: How does the "Anti-Tilt" mechanism proactively prevent falls?

A: Older primary students are often active and prone to rocking on their chairs. The angled rear frame shifts the leverage point further back, making it mechanically difficult for the chair to tip backwards, thereby proactively preventing accidents.

Q: Is the Apple Green shell resistant to school supply stains?

A: Yes. The high-grade polypropylene shell is non-porous. Juice spills, ink, or paints cannot penetrate the surface and can be wiped away easily without leaving residues or fading the vivid verdant colour.

Q: Can adults safely sit on these Size 4 chairs?

A: Yes. Despite being dimensioned for children, the 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: How easy are these chairs to store during cleaning?

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 for reconfiguration.

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: Why purchase from Cobolt Furniture?

A: With 50 years of manufacturing 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 UK curriculum.

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: How easy are these chairs to store during cleaning?

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 for reconfiguration.

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: Why purchase from Cobolt Furniture?

A: With 50 years of manufacturing 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 UK curriculum.
