Product Overview: EN1335 Certified Nylon-Backed Task Seating

Equip your administrative hubs with a seating solution engineered for relentless daily use. By integrating a solid polymer backrest with a high-shine chrome foundation, this task chair provides unyielding structural support while maintaining a sharp, professional corporate aesthetic.

Architectural Strength

  • Solid Nylon Backrest: Moving away from susceptible fabrics, the rigid black polymer backrest is highly resistant to impacts, scuffs, and tearing. It provides absolute, unbending support for the user's spine during intensive desktop activities.
  • EN1335 Accreditation: This unit has undergone rigorous independent testing to meet European standards for office furniture dimensions, safety, and mechanical endurance, ensuring it easily outlasts non-certified alternatives.
  • Chrome Metal Base: The high-tensile five-star base is finished in polished chrome, delivering exceptional weight-bearing capabilities (up to 120kg) and a premium metallic contrast to the black upper chassis.

Ergonomic Operator Mechanics

  • Airmesh Seat Pan: The base cushion is upholstered in a specialised, highly porous airmesh textile. This facilitates rapid heat dissipation and moisture control, keeping staff comfortable throughout a demanding eight-hour schedule.
  • Responsive Lock-Tilt: A robust under-seat mechanism allows users to rock backward fluidly to relieve pelvic pressure, or secure the chair entirely in a strict upright position for maximum data-entry focus.
  • Manual Tension Calibration: The integrated weight dial lets occupants manipulate the spring resistance of the chair's tilt, creating a perfectly balanced pivot that matches their individual stature and mass.

The Cobolt Standard

  • Complimentary Mainland Freight: We absorb all carriage overheads for your order. Your durable task seating arrives with Free Mainland UK Delivery included, preserving your estate's capital.
  • 50 Years of Industry Pedigree: Leveraging half a century of B2B expertise, we exclusively curate seating that is proven to endure the punishing realities of British educational trusts and commercial enterprises.
  • Domestic Manufacturing: Constructed locally within the United Kingdom, this product champions national supply chains, enforces strict quality oversight, and limits the carbon emissions tied to international shipping.

Frequently Asked Questions

1. What exactly does the EN1335 certification mean for my business?

A: EN1335 is an incredibly strict European standard for office seating. It means this chair has passed severe, repetitive mechanical tests for stability, structural strength, and ergonomic dimensions. It guarantees you are buying a product that will survive long-term commercial abuse.

2. Why choose a solid nylon backrest over a standard mesh or fabric one?

A: A solid polymer backrest provides unparalleled durability. It won't tear, stretch, or absorb spills like fabric, and it offers a much firmer, unyielding posture support system that is ideal for industrial or high-turnover environments.

3. What is an "airmesh" upholstered seat?

A: Airmesh is a highly porous, 3D-woven textile. Unlike flat fabrics or vinyl, its structure allows air to pass freely through the seat cushion, actively preventing heat and sweat build-up during long 8-hour shifts.

4. Will the chrome metal base rust over time?

A: The five-star base is heavily plated in commercial-grade chrome, which is highly resistant to corrosion and scuffing from footwear. A simple wipe down with a dry cloth will keep it gleaming in a standard indoor office environment.

5. How does the 120kg weight capacity compare to normal chairs?

A: Standard retail or light-office chairs generally max out at 100kg to 110kg. The 120kg rating (approx. 18.8 stone) on this unit denotes the use of a reinforced gas strut and a stronger metal base, delivering superior longevity.

6. Can I lock the chair into a reclined resting position?

A: No. This model is equipped with an upright tilt lock. While you can enjoy a fluid, tension-controlled rocking motion when it is released, the mechanism will only lock securely into place when positioned vertically at 90 degrees.

7. Will the fixed armrests collide with standard office desks?

A: The armrests sit at a height of 610mm from the floor. Given that standard UK work surfaces are typically 720mm to 750mm high, the chair will effortlessly slide beneath the vast majority of desks when not in use.

8. How is the warranty split between the different parts of the chair?

A: To provide comprehensive commercial assurance, the structural mechanics (the chrome base, gas cylinder, castors, and tilt lever system) are covered for 2 years. The softer components, namely the airmesh fabric and internal seat foam, carry a 1-year guarantee.

Product FAQs

Frequently Asked Questions

1. What exactly does the EN1335 certification mean for my business?

A: EN1335 is an incredibly strict European standard for office seating. It means this chair has passed severe, repetitive mechanical tests for stability, structural strength, and ergonomic dimensions. It guarantees you are buying a product that will survive long-term commercial abuse.

2. Why choose a solid nylon backrest over a standard mesh or fabric one?

A: A solid polymer backrest provides unparalleled durability. It won't tear, stretch, or absorb spills like fabric, and it offers a much firmer, unyielding posture support system that is ideal for industrial or high-turnover environments.

3. What is an "airmesh" upholstered seat?

A: Airmesh is a highly porous, 3D-woven textile. Unlike flat fabrics or vinyl, its structure allows air to pass freely through the seat cushion, actively preventing heat and sweat build-up during long 8-hour shifts.

4. Will the chrome metal base rust over time?

A: The five-star base is heavily plated in commercial-grade chrome, which is highly resistant to corrosion and scuffing from footwear. A simple wipe down with a dry cloth will keep it gleaming in a standard indoor office environment.

5. How does the 120kg weight capacity compare to normal chairs?

A: Standard retail or light-office chairs generally max out at 100kg to 110kg. The 120kg rating (approx. 18.8 stone) on this unit denotes the use of a reinforced gas strut and a stronger metal base, delivering superior longevity.

6. Can I lock the chair into a reclined resting position?

A: No. This model is equipped with an upright tilt lock. While you can enjoy a fluid, tension-controlled rocking motion when it is released, the mechanism will only lock securely into place when positioned vertically at 90 degrees.

7. Will the fixed armrests collide with standard office desks?

A: The armrests sit at a height of 610mm from the floor. Given that standard UK work surfaces are typically 720mm to 750mm high, the chair will effortlessly slide beneath the vast majority of desks when not in use.

8. How is the warranty split between the different parts of the chair?

A: To provide comprehensive commercial assurance, the structural mechanics (the chrome base, gas cylinder, castors, and tilt lever system) are covered for 2 years. The softer components, namely the airmesh fabric and internal seat foam, carry a 1-year guarantee.
