Info Overview

About the Lunhem.

The Lunhem is an ergonomic mesh task chair built around a honeycomb-structured suspension back, engineered for people who stay seated through long, focused working days. Four-dimensional armrests, a synchronised tilt mechanism and a sliding seat let each user shape the chair to their own body rather than adapting to it.


A Back That Breathes

  • Honeycomb Suspension Structure: A moulded polyamide frame carries a multi-layered, cellular weave that flexes where the body moves and firms up where it needs support.
  • Breathable Mesh Throughout: Air passes freely through the backrest and seat, so the chair stays comfortable through warm afternoons and long sessions at the desk.
  • Contoured Lumbar Support: The backrest follows the natural curve of the spine, holding posture without forcing it.

Adjusts to the Person, Not the Average

  • DONATI Synchronised Tilt: Seat and back move together at a fixed ratio, with lockable positions for upright work or a short recline.
  • Sliding Seat Depth: 590–630 mm of travel means taller and shorter users both get proper thigh support without pressure behind the knee.
  • 4D Armrests: Height, depth, width and pivot all adjust, so forearms stay supported whether typing, sketching or on a call.
  • Optional Headrest: A padded, height-adjustable headrest for users who lean back through video calls and reading.

Built to Stay in Service

  • Five-Star Base: Powder-coated steel or polished aluminium, rated to 136 kg.
  • Floor-Friendly Castors: 60 mm polyurethane wheels roll quietly and protect parquet and hard flooring.
  • Gas-Lift Height Range: 440–520 mm, covering standard and taller desk heights.

Certified and Recognised

  • BIFMA Certified: Independently tested for durability and long-term commercial performance.
  • Greenguard Certified: Verified for low chemical emissions, supporting healthier indoor air quality.
  • Award-Winning Design: Red Dot Award 2023, iF Design Award 2023 and International Design Excellence Award 2023.

Where It Works

  • Focused Desk Work: Full-day seating for open-plan floors and private offices.
  • Hybrid and Home Offices: Compact footprint with the adjustability of a full commercial task chair.
  • Shared Workstations: Quick, tool-free adjustment makes it practical for hot-desking.

A back that breathes

A back that breathes

The Lunhem is built around a moulded polyamide suspension frame carrying a multi-layered, honeycomb-structured mesh. The cellular weave flexes where the body moves and firms up where support is needed, while air passes freely through backrest and seat — so the chair stays comfortable through warm afternoons and long sessions at the desk.

A DONATI wire-control synchronised tilt moves seat and back together with lockable positions for upright work or a short recline. The sliding seat travels 590 to 630 mm, so taller and shorter users both get proper thigh support without pressure behind the knee. 4D armrests adjust for height, depth, width and pivot, and an optional padded headrest supports the neck for reading and video calls.

FAQ Lunhem

Questions about this product.

All FAQs
How is the Lunhem's back different from a normal mesh chair?

The Lunhem carries a moulded polyamide suspension frame with a multi-layered, honeycomb-structured mesh. The cellular weave flexes where the body moves and firms up where support is needed, while air passes freely through both backrest and seat. The mesh itself is a fine, tear-resistant fabric from Kusch+Co in Germany.

Can the Lunhem be adjusted for different body sizes?

Yes. Seat height covers 440 to 520 mm and the seat pan slides between 590 and 630 mm of depth, so both taller and shorter users get proper thigh support. 4D armrests adjust for height, depth, width and pivot, and a synchronised tilt with multiple lockable positions lets users choose an upright or reclined working posture.

Is the headrest included?

The headrest is optional. The padded, height-adjustable headrest measures 160 by 70 mm and is well suited to users who lean back through video calls or reading. Please specify the variant with or without headrest when ordering.

Are the castors suitable for parquet and hard floors?

Yes. The Lunhem comes with 60 mm polyurethane castors designed specifically for hard flooring. They roll quietly and protect parquet, laminate and other smooth surfaces, so no additional floor mat is required.

What is the maximum load and warranty?

The Lunhem is rated for a maximum user weight of 136 kg. Warranty covers 8 years on the mechanism, 5 years on the gas lift and armrest pads, and 2 years on the fabric and mesh, subject to normal commercial use and T&Cs.
