Product Overview: Size 4 Green Reinforced Primary Chair

The Cobolt Green Reinforced Chair is the industry-standard choice for senior primary school classrooms. Dispatched with Free UK Mainland Delivery, it is built to survive the "school test"—constant daily usage, classroom transitions, and the energetic environment of 8-to-11-year-olds.

The Cobolt Advantage

  • Unmatched Durability: Our industry-leading 15-year guarantee protects your procurement budget, ensuring these chairs serve multiple generations of Key Stage 2 pupils.
  • Efficient Space Management: These units stack securely up to 10 high, allowing classrooms, libraries, and dining halls to be cleared quickly for cleaning or physical activities.
  • Staff-Friendly Identification: Colour-coded anti-slip feet correspond to the Size 4 standard, enabling site teams to instantly identify and organise height-appropriate furniture across the school.

Ergonomics & Sustainability

  • BS EN1729 Compliance: Perfectly scaled for the 8-11 age demographic (Size 4), the shell promotes correct spinal alignment during a vital stage of student growth.
  • Eco-Responsible Lifecycle: The chair is designed for a circular economy; it can be fully disassembled into plastic and metal components for responsible specialist recycling.
  • Advanced Support: The anatomically moulded shell provides essential lumbar support, helping older children stay focused and comfortable during core subject lessons.

Anti-Tamper Construction

We prioritise classroom safety and maintenance. By removing all nuts and screws from the exterior, we have created a smooth, tamper-proof chair that removes the risk of small parts being loosened or clothing being snagged.

The Cobolt Standard

  • Free UK Mainland Delivery: We handle all shipping costs at no extra charge, keeping your refurbishment project strictly on budget.

FAQs: The UK’s Leading School Seating Solutions

Q: Is "Size 4" the correct choice for my Year 6 classroom?

A: Yes. Size 4 is the industry standard for children aged 8 to 11 years. With a seat height of 380mm, it is designed to support pupils as they prepare for the transition to secondary school dimensions.

Q: How does the "anti-tilt" feature protect students?

A: The chair's frame geometry shifts the centre of gravity, making it mechanically difficult for students to lean back on two legs. This is a proactive safety feature that reduces falls in the classroom.

Q: Why is the "no nuts or screws" design important for Key Stage 2?

A: At this age, students can be more inquisitive. Our anti-tamper design means there are no external fixings to be loosened, and no sharp edges to snag school uniforms or blazers.

Q: Can these chairs be safely stacked?

A: Absolutely. These reinforced chairs stack stably up to 10 units high, allowing site teams to clear halls or classrooms quickly for different activities.

Q: What is the purpose of the colour-coded feet?

A: The feet are coloured to correspond with the "Size 4" specification. This allows staff to instantly identify height-appropriate furniture when chairs are moved between rooms.

Q: Is the Green plastic easy to sanitise?

A: Yes. The high-grade polypropylene is non-porous and easy to clean. A simple wipe with a damp cloth and mild detergent will maintain high hygiene standards across the school.

Q: Are these chairs genuinely British made?

A: Yes. Every chair is designed and manufactured in the UK. This ensures superior build quality, a low carbon footprint, and faster availability for our UK customers.

Q: Why purchase from Cobolt Furniture?

A: With 50 years of heritage, we are a trusted partner to UK education. We offer Free UK Mainland Delivery, a 15-year warranty, and expert advice to simplify your procurement.
