Product Overview: Size 6 Sky Blue Classic Skid-Base Chair

The Cobolt Sky Blue Skid-Base Chair is engineered specifically for the modern learning environment. Supplied with Free UK Mainland Delivery, it is designed to survive the "school test"—constant movement, heavy daily use, and the high-pressure environment of secondary and higher education.

The Cobolt Advantage

  • Budget Longevity: With a 15-year warranty, we eliminate frequent replacement cycles, ensuring your furniture budget goes significantly further over the next decade
  • Estates-Friendly Design: Our skid-base frames glide rather than gouge, protecting vinyl and laminate floor investments from expensive resurfacing costs
  • Classroom Safety & Focus: Anti-tilt geometry removes the distraction of "swinging" on chairs, reducing the risk of falls and keeping the classroom environment orderly

Ergonomics & Sustainability

  • BS EN1729 Compliant: Dimensioned for "Size 6" (ages 14 to adult), the shell supports the natural "S" curve of the spine to prevent chronic back pain
  • Eco-Conscious Choice: Proudly UK-manufactured using 100% recyclable polypropylene and steel, supporting your school’s carbon reduction targets
  • Waterfall Edge: The curved front seat maintains healthy blood flow during double periods or exam sessions, preventing student restlessness

Vandal-Resistant Build

Classroom furniture must be tamper-proof. We utilise high-security fasteners to ensure the seat shell remains permanently attached to the frame, preventing students from dismantling the unit in busy environments.

  • 50 Years of Heritage: We are a trusted partner to the UK public sector, providing furniture that meets strict education compliance standards
  • Free UK Mainland Delivery: We absorb shipping costs to keep school procurement simple and transparent

FAQs: The UK’s Leading School Seating Solutions

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

A: Size 6 is the industry standard for users with a stature range of 1590mm to 1880mm. It corresponds to a seat height of 460mm, making it the essential choice for Secondary Schools (Year 10+), Sixth Forms, Colleges, and Universities. It is designed to comfortably accommodate fully grown students and adult staff.

Q: Why is a skid-base frame better for school floors than 4 legs?

A: Traditional 4-leg chairs concentrate 100% of the pressure on four small points, often gouging vinyl and laminate floors. The steel skid base acts as a continuous rail, spreading user weight evenly. This protects your floor investment and allows the chair to move quietly—vital for exam halls and libraries.

Q: How effective is the Anti-Tilt frame for classroom safety?

A: It is highly effective. By angling the rear frame back, the centre of gravity is shifted. This makes it mechanically difficult for a student to lean back dangerously on two legs, a proactive design feature that significantly reduces the risk of falls and spinal injuries in the classroom.

Q: Does this chair comply with BS EN1729 standards?

A: Yes. This chair is fully compliant with BS EN1729 Parts 1 & 2. Part 1 covers the ergonomic dimensions required to promote good posture, while Part 2 certifies the structural strength and stability needed for heavy-duty institutional use.

Q: What is the maximum weight limit for these chairs?

A: These chairs are engineered for durability and are rated for a maximum user weight of 125kg (approx. 19 stone). This robust capacity ensures they are safe for use by senior students as well as adult learners and teaching staff.

Q: Can these chairs be stacked for storage?

A: Yes. The skid-base frame is designed for stable vertical stacking up to 5 high. This is perfect for multi-use school halls or for clearing classrooms quickly for cleaning and floor maintenance.

Q: Are the shells "tamper-proof" to prevent vandalism?

A: We understand the rigours of school life. The polypropylene shells are secured to the steel frames using tamper-proof fasteners. This prevents students from dismantling the units, ensuring your furniture remains safe and structurally sound for years.

Q: Is the Sky Blue colour UV-stable and easy to clean?

A: Yes. The high-grade polypropylene is UV-stabilised to prevent fading in sunny classrooms. The non-porous surface is resistant to ink and chemicals; simply wipe with warm soapy water to maintain high hygiene standards across your estate.

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, a market-leading 15-year warranty, and expert advice to ensure your procurement process is simple and efficient.

Product FAQs

FAQs: The UK’s Leading School Seating Solutions

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

A: Size 6 is the industry standard for users with a stature range of 1590mm to 1880mm. It corresponds to a seat height of 460mm, making it the essential choice for Secondary Schools (Year 10+), Sixth Forms, Colleges, and Universities. It is designed to comfortably accommodate fully grown students and adult staff.

Q: Why is a skid-base frame better for school floors than 4 legs?

A: Traditional 4-leg chairs concentrate 100% of the pressure on four small points, often gouging vinyl and laminate floors. The steel skid base acts as a continuous rail, spreading user weight evenly. This protects your floor investment and allows the chair to move quietly—vital for exam halls and libraries.

Q: How effective is the Anti-Tilt frame for classroom safety?

A: It is highly effective. By angling the rear frame back, the centre of gravity is shifted. This makes it mechanically difficult for a student to lean back dangerously on two legs, a proactive design feature that significantly reduces the risk of falls and spinal injuries in the classroom.

Q: Does this chair comply with BS EN1729 standards?

A: Yes. This chair is fully compliant with BS EN1729 Parts 1 & 2. Part 1 covers the ergonomic dimensions required to promote good posture, while Part 2 certifies the structural strength and stability needed for heavy-duty institutional use.

Q: What is the maximum weight limit for these chairs?

A: These chairs are engineered for durability and are rated for a maximum user weight of 125kg (approx. 19 stone). This robust capacity ensures they are safe for use by senior students as well as adult learners and teaching staff.

Q: Can these chairs be stacked for storage?

A: Yes. The skid-base frame is designed for stable vertical stacking up to 5 high. This is perfect for multi-use school halls or for clearing classrooms quickly for cleaning and floor maintenance.

Q: Are the shells "tamper-proof" to prevent vandalism?

A: We understand the rigours of school life. The polypropylene shells are secured to the steel frames using tamper-proof fasteners. This prevents students from dismantling the units, ensuring your furniture remains safe and structurally sound for years.

Q: Is the Sky Blue colour UV-stable and easy to clean?

A: Yes. The high-grade polypropylene is UV-stabilised to prevent fading in sunny classrooms. The non-porous surface is resistant to ink and chemicals; simply wipe with warm soapy water to maintain high hygiene standards across your estate.
