Details
The PelicanWork Model 77 Ergonomic Office Chair is what happens when an ergonomic chair stops trying to look like a chunky machine—and starts feeling like one smooth, floating system. Under the seat, a hollow, open-frame mechanism replaces the usual bulky “black box,” giving the chair a light, cloud-like silhouette while letting you see the engineering that usually gets hidden.
The magic is in motion: the AeroFusion Drive and multi-axis synchro-tilt are built to adapt naturally as you lean back—so reclining feels instinctive, not like you’re negotiating with levers every hour. As you move, the seat, armrests, and backrest travel together along an ergonomic path that keeps support steady across postures—especially when you lean back at your desk and your arms need to stay “with you,” not drift away.
Wrapped in full breathable mesh (back + seat), Model 77 stays cool through long workdays and longer nights—while key comfort points stay adjustable and precise, including height-adjustable lumbar support and an optional headrest for neck support.
Direct build cost split into materials, mechanism and labour & shipping.
Upholstery & Feel
- Full mesh design (seat + backrest) for all-day airflow.
- Mesh spec: Wintex “high-oxygen tech mesh” (Korea) for durability, breathability, and elasticity.
Mechanism & Motion
- AeroFusion Mechanism / open chassis: hollow structure replacing the traditional bulky mechanism housing (“black box”) for a lighter visual + mechanical system.
- Multi-axis synchro-tilt: designed to self-adapt so you can recline naturally without constant manual tweaking; seat/armrests/back move in harmony.
- Kinematics detail highlighted by the design team: 1° : 2° : 3° motion ratio between seat, armrests, and backrest so your whole body (including arms) moves together during recline.
Adjustability
- Lumbar support: height adjustable by 60 mm.
- Headrest (optional): height adjustment range 60 mm.
- Armrests: 2D with horizontal + vertical adjustment.
- Core controls shown: seat height adjustment + tilt lock.

Model 77 Adjustments

AeroFusion Mechanism Design
The PelicanWork Model 77 Office Chair features a hollow, open-frame mechanism that replaces the bulky “black box” with a light, cloud-like silhouette under the seat. Its transparent AeroFusion Drive delivers dynamic support and smooth, natural reclining, while the clear tilt assembly reveals the springs and linkage rods—turning engineering into part of the chair’s visual identity, not something hidden.

Synchro-Tilt Mechanism
The PelicanWork Model 77 Office Chair uses a specially engineered multi-axis synchro-tilt that adapts naturally as you move, so you can lean back freely without constantly fiddling with manual adjustments. The backrest, armrests, and seat travel together along an ergonomic motion path to keep support consistent across postures, making long gaming or work sessions feel stable, comfortable, and effortless.
Why Model 77 Stands Out
Model 77 is a premium ergonomic office chair designed for people who want long-hour comfort, breathable support, and a cleaner modern look than bulky traditional office chairs. Instead of hiding the mechanism inside a heavy under-seat box, Model 77 uses an open-frame engineering design that gives the chair a lighter, more refined silhouette while still keeping the support and adjustability expected from a serious ergonomic work chair.
It is made for modern workspaces where the chair has to do more than simply look professional. Whether you are setting up a home office, working long hours at a desk, building a focused study space, or upgrading a professional workstation, Model 77 is designed to support the body through changing postures. Its breathable mesh seat and back help reduce heat build-up, while its reclining movement, lumbar support, and synchronized ergonomic motion make it a strong choice for anyone searching for a mesh office chair for long hours.
Design, Materials & Ergonomic Features
Model 77 is built around PelicanWork’s AeroFusion Drive and open-frame mechanism, which replaces the usual bulky under-seat housing with a more transparent and lightweight mechanical architecture. This gives the chair a floating, engineered appearance while allowing the movement system to become part of the design language instead of something hidden from view.
The chair uses full breathable mesh across both the backrest and seat, making it especially suitable for long working hours in Indian weather, warm offices, and home workspaces where heat and sweat can become a real comfort problem. Unlike dense foam chairs that can trap warmth over time, the mesh construction helps maintain airflow while giving the chair a lighter, more responsive sitting feel.
Ergonomically, Model 77 is designed to move with the user. Its multi-axis synchro-tilt system helps the seat, backrest, and armrests travel together as you recline, so the chair continues to support you when you lean back instead of forcing your body to readjust. This is especially useful for people who alternate between typing, reading, thinking, video calls, and relaxed desk work throughout the day.
Key comfort features include height-adjustable lumbar support for lower-back positioning, smooth reclining support for posture changes, full mesh comfort for all-day airflow, and an optional headrest for users who want added neck and upper-back support. For search intent around ergonomic office chair, mesh office chair, reclining office chair, adjustable office chair, office chair with lumbar support, and office chair for long hours, Model 77 offers a more advanced and design-led alternative to generic task chairs.
Who It’s Best For
Model 77 is best for professionals, founders, creators, designers, developers, students, and desk users who spend long hours sitting and want an ergonomic office chair that feels supportive without looking heavy. It is a strong fit for home offices, corporate workstations, executive desks, study rooms, startup offices, and hybrid work setups where comfort, airflow, adjustability, and visual design all matter.
If you are looking for a breathable mesh office chair for long work sessions, a reclining office chair that supports posture changes, or a premium ergonomic chair that looks lighter and more modern than conventional office chairs, Model 77 is designed for that exact use case. It gives you the support of a performance work chair with a cleaner, more architectural design language.
