Product Information

Full details

The Eclipse I Lever Draughtsman Operator Chair is an ideal seating solution for professionals in drafting, laboratory, or high-counter environments who require ergonomic support during extended tasks. Its primary strength lies in its highly adjustable architecture, offering both seat depth and backrest positioning to accommodate diverse body types. While it provides excellent foundational support with its cushioned waterfall seat, users should note that the single-lever mechanism requires a brief adjustment period to master the dual-function controls.

FAQs

Is this chair suitable for a standard 29-inch desk?

This chair is specifically designed as a draughtsman model, meaning its minimum height is generally higher than standard operator chairs. It is best suited for standing-height or adjustable drafting desks.

Can I remove the backrest?

While the backrest is removable for maintenance or transit, it is designed to be a permanent part of the ergonomic support structure and should remain attached for daily use.

Does the chair swivel 360 degrees?

Yes, the chair features a full 360-degree swivel base to allow for easy movement between tools and surfaces in a workspace.

What is the weight capacity of the Eclipse 1?

The chair is built for standard commercial use and is tested to support up to 110kg safely.

Are the casters safe for wooden floors?

The chair comes with standard casters, but using a protective floor mat is recommended for hardwood floors to prevent scratching over time.

How do I adjust the seat depth?

Use the seat depth adjustment lever to slide the seat pan forward or backward, then release the lever to lock it into your preferred position.

Troubleshooting

Chair height keeps sinking

Check if the gas lift cylinder is fully engaged in the base. If it continues to sink, the gas lift may require a replacement component.

Backrest feels loose or wobbly

Locate the tension adjustment bolts behind the backrest mount and tighten them firmly with an Allen key.

Lever is difficult to engage

Ensure you are applying the correct pressure; sometimes shifting your weight off the chair while lifting the lever makes the mechanism move more freely.

Pros and Cons

Pros

  • Ergonomic waterfall seat edge promotes better circulation
  • Highly adaptable for tall desks or drafting tables
  • Contoured backrest provides reliable lumbar support
  • Adjustable seat depth caters to various leg lengths
  • Simple, durable design suitable for high-traffic environments

Cons

  • Single lever requires learning the control sequence for angle vs. height
  • Lacks adjustable armrests for users who prefer forearm support
  • Best suited for specific high-counter tasks rather than executive lounge use

Setup, Compatibility & Care

To assemble the chair, ensure the gas lift is firmly seated into the five-star base before attaching the seat pan. The chair is compatible with standard hard-floor surfaces, though chair mats are recommended to prevent excessive caster wear. To care for your Eclipse chair, vacuum the cushioned fabric regularly to prevent dust accumulation. For minor spills, spot clean with a mild soap solution and a damp cloth; avoid soaking the cushion to maintain the integrity of the foam. Check and tighten all adjustment bolts every six months to ensure smooth operation of the lever mechanism.
