The Cobolt Advantage

FAQs: The UK’s Leading School Seating Solutions

Q: What is the "Size 4" 380mm height suitable for?

A: Size 4 (380mm seat height) is the industry standard for children aged 8-11 years. It is specifically dimensioned for upper-primary students (Years 4, 5, and 6), ensuring their feet rest comfortably on the floor while maintaining correct spinal alignment.

Q: Why are the feet colour-coded on school chairs?

A: Colour-coding the feet is an estates-friendly feature that allows staff to instantly identify the seat height of a chair from a distance. This simplifies room reconfigurations and furniture audits in large primary schools.

Q: What does "FIRA Certified" mean for my school?

A: FIRA Certification means the chair has been independently tested by the Furniture Industry Research Association. It confirms the chair meets strict British and European standards for school furniture strength, stability, and ergonomics.

Q: How many of these chairs can be safely stacked?

A: These traditional 4-legged chairs are designed for high-density storage and can be safely stacked up to 8 high. This is ideal for clearing classrooms for deep cleaning or for school events.

Q: How do I maintain these chairs for the long term?

A: We recommend checking the frame and top connections every six months. The feet should be inspected periodically and replaced if worn. For cleaning, simply use a warm, damp cloth and a non-abrasive cleaner.

Q: Are these primary school chairs environmentally friendly?

A: Yes. These chairs are designed for a circular economy. They can be completely disassembled into metal and plastic parts, allowing each material to be responsibly recycled at the end of their service life.

Q: What is the standard delivery time for these chairs?

A: Our standard delivery time is 4 weeks. Please note that during peak periods, specifically the school summer holidays, lead times may extend. We recommend ordering early for September school refits.

Q: Why should my school buy from Cobolt Furniture?

A: With over 50 years of heritage, we are a trusted partner to the UK public sector. We offer Free UK Mainland Delivery, FIRA-certified products, and a commitment to sustainability that helps your school estate run responsibly.
