Product Overview: Ergonomic Red Operator Chair with Integrated Arms

Optimise your workstation with a chair that combines a high-impact red finish with clinical ergonomic flexibility. This operator chair is engineered to support long-term productivity, providing a stable and highly adjustable platform that thrives in both busy school administrative offices and corporate environments.

The Cobolt Advantage

  • Independent Back Rake Control: Gain total command over your seating posture. This mechanism allows you to adjust the tilt of the backrest separately from the seat, providing a bespoke recline angle that can be locked into multiple positions for focused or relaxed work.
  • Adjustable Lumbar Targeting: The manual back height control ensures that the anatomically contoured backrest sits exactly where you need it. By aligning the support with the natural curve of your spine, you significantly reduce the risk of posture-related fatigue.
  • Stable Fixed Armrests: Integrated armrests provide a permanent, grounded support system for the forearms and elbows. This reduces the strain on the trapezius muscles and shoulders, which is essential during prolonged typing sessions.

Durability & Safety Compliance

  • Commercial-Grade Red Upholstery: Upholstered in a heavy-duty technical red fabric, the seat and back are designed to resist pilling and abrasion, maintaining a professional and vibrant look even in high-traffic administrative hubs.
  • EN 1335 Certified Standards: This chair meets strict EN 1335-1:2000 and EN 1335-2:2018 criteria. It has been independently verified to meet the rigorous safety and structural requirements of a professional commercial office chair.
  • Precision Gas Lift: Equipped with a high-performance gas strut for smooth height adjustment (460-570mm), ensuring users can keep their feet flat on the floor for optimal pelvic health.

The Cobolt Standard

  • Free Mainland UK Delivery: We manage all transport logistics to ensure your budget is spent on quality equipment, not carriage. Every red task chair includes Free Mainland UK Delivery for total cost transparency.

  • UK Design Heritage: This chair is thoughtfully Designed in the UK, ensuring the proportions and mechanical adjustments meet the specific ergonomic needs of the modern British workforce.

A: Yes. You can manually raise or lower the backrest. This is essential for ensuring the integrated lumbar contour aligns perfectly with the small of your back to prevent fatigue.

5. What is the maximum weight the chair can hold?

A: This chair is structurally rated for a maximum user weight of 110kg (approximately 17 stone), which is the industry standard for daily commercial office seating.

6. Will the armrests fit under a standard school desk?

A: Absolutely. The chair is designed with standard UK workstation dimensions in mind. Most desks are 720-750mm high, and this chair will comfortably tuck under most work surfaces when not in use.

7. Is assembly difficult once the chair arrives?

A: Not at all. The chair arrives with clear instructions and all required fixings. Most users find they can have it built and ready for work in approximately 10-15 minutes.

8. What is included in the 3-year warranty?

A: Our 3-year commercial warranty provides comprehensive cover for all mechanical components—including the gas lift and tilt adjustments—and any structural defects in the frame.
