Product Overview: Sky Blue Classic Polypropylene Swivel Computer Chair

The Cobolt CH61SK is a heavy-duty swivel chair specifically designed for "severe use" in secondary classrooms, IT labs, and libraries. Supplied with Free UK Mainland Delivery, it combines a serene Sky Blue aesthetic with the structural resilience required for high-traffic educational settings.

The Cobolt Advantage

  • Budget-Friendly Durability: Protected by a 5-year commercial manufacturer warranty, this chair is a long-term asset designed to outlast standard retail furniture in a school environment.
  • Security-Minded Design: Integrated tamperproof fixings ensure the shell remains safely and permanently attached to the swivel frame, deterring student interference.
  • Dynamic Learning Mobility: The reinforced 5-arm star base and high-quality castors facilitate easy transitions between focused screen time and collaborative group activities.

Ergonomics & Sustainability

  • Postural Correction: The anatomically sculpted shell is designed to support the spine’s natural curvature, aiding concentration during intensive digital projects.
  • Circulation Support: The waterfall front seat edge prevents pressure on the underside of the thighs, ensuring students remain comfortable during double lesson periods.
  • Circular Economy Commitment: 100% recyclable at end-of-life; the modular construction allows for effortless disassembly into metal and plastic components for responsible recycling.

Institutional Build Quality

Our ICT furniture is tested to a much higher standard than domestic seating. With a weight capacity of 100kg and a shell manufactured from stain-resistant, impact-tested polypropylene, the CH61SK is engineered for the "school test."

FAQs: The UK’s Leading ICT Seating Solutions

Q: How complex is the assembly for this chair?

A: Very simple. The chair requires basic assembly to connect the Sky Blue seat shell, the gas lift, and the 5-castor base. This modular design also ensures that components can be separated for future recycling.

Q: Is this chair suitable for secondary school students?

A: Absolutely. With a heavy-duty 100kg weight limit and height adjustment up to 520mm, this chair is specifically designed for students in Years 7-13, as well as adult learners and staff.

Q: Is the polypropylene shell stain-resistant?

A: Yes. The high-impact plastic is resistant to ink, chemicals, and general classroom dirt. It can be easily wiped clean with a warm, damp cloth and a non-abrasive cleaner.

Q: What is the benefit of the waterfall front?

A: The waterfall front edge curves downwards. This prevents the seat from pressing into the underside of the student's legs, maintaining healthy blood flow and comfort during long computer sessions.

Q: Will the Sky Blue colour fade?

A: No. The shell is manufactured from UV-stable polypropylene, which means the Sky Blue finish will remain bright and professional even in rooms with plenty of natural sunlight.

Q: Why are tamperproof fixings important?

A: Tamperproof fixings require specialized equipment to remove. This prevents students from dismantling the chairs, ensuring they remain safe and structurally sound for their entire lifespan.

Q: What is covered by the 5-year warranty?

A: Our 5-year guarantee covers all structural failures and manufacturer defects for the shell, frame, and gas lift mechanism under standard school usage.

Q: Why should my school buy from Cobolt?

A: With over 50 years of heritage, we specialize in seating that outlasts the competition. We offer Free UK Mainland Delivery and products that are rigorously tested to meet British education standards.
