Product Overview: Lightweight Grey-Frame Mesh Task Chair

Bridging the gap between a standard office chair and an agile collaborative seat, this mesh task chair is designed for the fluid reality of modern work. Its weight-balanced engineering ensures that multiple users can share a single workstation while enjoying immediate, personalised comfort without complex manual adjustments.

The Cobolt Advantage

  • Self-Weight Active Mechanism: The internal tension system automatically detects the user's body weight, providing a smooth and effortless reclining action that is perfectly calibrated to whoever is sitting in the chair.
  • Synchronised Tilt & Lock: The seat and backrest move in harmony to maintain optimal support for the lower back. With multiple lockable positions, users can find and fix their preferred angle for deep focus or relaxed collaboration.
  • Agile Two-Tone Design: The contemporary contrast between the grey frame components and the black mesh back makes this chair a versatile design asset that complements both professional corporate offices and creative educational studios.

Organisation & Personalisation

  • Sliding Seat Depth: Tailor the chair to your frame. The seat pan can be adjusted forwards or backwards, ensuring that taller and shorter users alike can maintain proper circulation and support behind the knees.
  • Breathable Mesh Back: The high-tensile black mesh promotes airflow, preventing heat build-up against the spine during long periods of work, keeping the user cool and comfortable in climate-controlled environments.
  • Integrated Gas Lift: Precision height adjustment allows users to align their eye level perfectly with monitors or work surfaces, significantly reducing neck strain and promoting better desk ergonomics.

The Cobolt Standard

  • Free Mainland UK Delivery: At Cobolt, we absorb all heavy freight logistics. Your office seating is delivered via Free Mainland UK Delivery, protecting your procurement budget from unexpected carriage surcharges.
  • 50 Years of Mastery: We leverage five decades of commercial B2B expertise to source and supply furniture that genuinely withstands the rigorous, daily usage of UK professional and educational estates.
  • Commercial Strength Assurance: Built with a 110kg maximum weight capacity and a 3-year warranty, this chair is engineered specifically for long-term commercial application rather than light domestic use.

Ideal Environments for the Black Mesh Task Chair

With its lightweight profile and intuitive weight-balanced mechanism, this chair is the premier specification for Touchdown Workspaces, Hot-Desking Zones, and Collaborative Meeting Rooms. Its durable build and mesh breathability also make it a favourite for Sixth Form Study Centres and Higher Education Libraries.

Key Features

  • Weight-Active Mechanism — Intelligently adjusts the recline tension based on the user's weight for an effortless "zero-adjustment" experience.
  • Synchro Seat & Back Tilt — Maintains a healthy angle between the torso and thighs, lockable in multiple positions for bespoke comfort.
  • Adjustable Seat Depth — Seat slides horizontally to accommodate different leg lengths and provide optimal lumbar alignment.
  • Gas Lift Height Adjustment — Smooth seat height transition (440-535mm) to suit various desk heights and user statures.
  • Grey & Black Two-Tone Frame — A modern, professional aesthetic that blends into any contemporary architectural interior.
  • 110kg Maximum Capacity — A robust structural rating that ensures safety and longevity in high-use commercial settings.
  • Breathable Mesh Construction — High-quality mesh backrest provides consistent lumbar support while ensuring maximum air circulation.

Frequently Asked Questions

1. What is a "Self-Weight Active Mechanism"?

A: It is an intuitive tilt system that automatically adjusts the resistance of the backrest based on the weight of the person sitting in it. This means multiple users can use the same chair without constantly fiddling with tension knobs.

2. Is this chair suitable for an 8-hour working day?

A: Yes. With its synchronised tilt, lockable positions, and seat depth adjustment, this chair provides the high-level ergonomic support required for full-time office or study use.

3. Why is "Seat Depth Adjustment" important?

A: Seat depth (or seat slide) allows you to move the seat forwards or backwards. This is vital to ensure that people of different heights can achieve a posture that supports their thighs without putting pressure on the back of the knees.

4. Can the chair be used by several different people in a hot-desking area?

A: Absolutely. In fact, that is exactly what it was designed for. The lightweight frame and weight-responsive mechanism make it perfect for shared workspaces where users change throughout the day.

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

A: The chair is structurally rated for a maximum capacity of 110kg (approximately 17 stone), which is the standard for commercial office furniture.

6. Will the armrests fit under my desk?

A: The arms have a height range of 640mm to 735mm from the floor. Most standard desks are 720-750mm high, so the chair will comfortably slide underneath most workstations when not in use.

7. Is the chair delivered ready-to-use?

A: The chair requires some simple assembly upon arrival. It comes with clear instructions and all necessary fixings to ensure it can be built and deployed in your workspace in minutes.

8. What does the 3-year warranty cover?

A: The 3-year commercial warranty covers all mechanical failures, including the gas lift, tilt mechanism, and structural frame defects arising from normal office usage.

2. Is this chair suitable for an 8-hour working day?

A: Yes. With its synchronised tilt, lockable positions, and seat depth adjustment, this chair provides the high-level ergonomic support required for full-time office or study use.

3. Why is "Seat Depth Adjustment" important?

A: Seat depth (or seat slide) allows you to move the seat forwards or backwards. This is vital to ensure that people of different heights can achieve a posture that supports their thighs without putting pressure on the back of the knees.

4. Can the chair be used by several different people in a hot-desking area?

A: Absolutely. In fact, that is exactly what it was designed for. The lightweight frame and weight-responsive mechanism make it perfect for shared workspaces where users change throughout the day.

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

A: The chair is structurally rated for a maximum capacity of 110kg (approximately 17 stone), which is the standard for commercial office furniture.

6. Will the armrests fit under my desk?

A: The arms have a height range of 640mm to 735mm from the floor. Most standard desks are 720-750mm high, so the chair will comfortably slide underneath most workstations when not in use.

7. Is the chair delivered ready-to-use?

A: The chair requires some simple assembly upon arrival. It comes with clear instructions and all necessary fixings to ensure it can be built and deployed in your workspace in minutes.

8. What does the 3-year warranty cover?

A: The 3-year commercial warranty covers all mechanical failures, including the gas lift, tilt mechanism, and structural frame defects arising from normal office usage.
