FAQs: Leading Secondary & Adult Learning Seating

Q: What is a "Size 6" chair and is it suitable for my students?

A: Size 6 is the industry standard for users aged 14 years and above, including adults. With a 460mm seat height, it ensures that users' feet are flat on the floor to promote correct spinal health in secondary schools and colleges.

Q: How does the "Anti-Tilt" feature help with classroom management?

A: Older students are often prone to "chair swinging". The angled rear frame changes the leverage point, making it mechanically difficult for the chair to tip backwards. This proactively reduces accidents and focus disruptions.

Q: Is the white colour difficult to keep clean in a busy institution?

A: No. The polypropylene material is non-porous and resistant to ink and common chemicals. It can be wiped clean instantly with standard anti-bacterial sprays, ensuring your environment maintains a high level of hygiene.

Q: What is the maximum weight capacity of this chair?

A: Despite being lightweight, the high-strength steel frame has an adult-grade load capacity of 125kg. This ensures it is robust enough for all senior students and adult staff.

Q: Are these chairs easy for estates teams to manage?

A: Yes. Weighing 4.3kg, they are robust but remain manageable for staff. They also stack safely, allowing teams to clear floor space efficiently for cleaning or exams.

Q: Does the chair meet UK safety standards?

A: Absolutely. It is fully compliant with BS EN1729, meaning it meets the specific requirements for ergonomic posture and structural durability for use in UK educational settings.

Q: Is the chair sustainable for my environmental policy?

A: Yes. At the end of its life, the chair can be separated into its plastic and steel components, both of which are 100% recyclable. This supports your commitment to carbon reduction targets.

Q: What does the 15-year warranty cover?

A: The warranty covers any structural failure in the frame welds or the integrity of the shell due to manufacturing defects. This provides your institution with exceptional long-term budget security.

Q: Why choose Cobolt Furniture for secondary seating?

A: With over 50 years of heritage, we are a trusted partner to UK education providers. We offer Free UK Mainland Delivery, expert advice, and products designed specifically for high-traffic environments.

A: Older students are often prone to "chair swinging". The angled rear frame changes the leverage point, making it mechanically difficult for the chair to tip backwards. This proactively reduces accidents and focus disruptions.

Q: Is the white colour difficult to keep clean in a busy institution?

A: No. The polypropylene material is non-porous and resistant to ink and common chemicals. It can be wiped clean instantly with standard anti-bacterial sprays, ensuring your environment maintains a high level of hygiene.

Q: What is the maximum weight capacity of this chair?

A: Despite being lightweight, the high-strength steel frame has an adult-grade load capacity of 125kg. This ensures it is robust enough for all senior students and adult staff.

Q: Are these chairs easy for estates teams to manage?

A: Yes. Weighing 4.3kg, they are robust but remain manageable for staff. They also stack safely, allowing teams to clear floor space efficiently for cleaning or exams.

Q: Does the chair meet UK safety standards?

A: Absolutely. It is fully compliant with BS EN1729, meaning it meets the specific requirements for ergonomic posture and structural durability for use in UK educational settings.

Q: Is the chair sustainable for my environmental policy?

A: Yes. At the end of its life, the chair can be separated into its plastic and steel components, both of which are 100% recyclable. This supports your commitment to carbon reduction targets.

Q: What does the 15-year warranty cover?

A: The warranty covers any structural failure in the frame welds or the integrity of the shell due to manufacturing defects. This provides your institution with exceptional long-term budget security.

Q: Why choose Cobolt Furniture for secondary seating?
