Spencer Ergonomic Chair

Spencer Ergonomic Chair - Four-Leaf Clover Backrest with Independent Lumbar Support

The Shappa Spencer Ergonomic Chair is built around a four-leaf clover 4-zone backrest — breathable mesh across the upper back, with a flexible TPU band through the two lumbar zones below. The lumbar support has its own independent adjustment mechanism, separate from the backrest recline and height controls, letting you adjust it up and down across 3 steps to change support strength and position — a more precise alternative to the single fixed pads found on many ergonomic chairs.

Beyond lumbar support, Spencer is built for long working hours and larger body types. A heavy-duty aluminium frame and Class-4 BIFMA-certified gas lift support up to 150kg, and the chair suits users from 150-200cm tall. Six-way adjustable armrests, a height-adjustable headrest, and an extendable footrest round out a chair designed to be customised to your exact posture.

Key Features of the Spencer Ergonomic Chair

Four-Leaf Clover Backrest with Independent Lumbar Support

The backrest uses a four-leaf clover 4-zone suspension design — breathable mesh across the upper two zones, flexible TPU across the two lumbar zones below — and the TPU lumbar band has its own independent adjustment mechanism — separate from the backrest recline and height controls — letting you dial in support strength and position across 3 steps to match your lower back. This is one of the key differences between Spencer and Shappa's other ergonomic chairs — a dedicated, independently adjustable lumbar support rather than a single fixed pad or a system that only moves in sync with the recline.

6D Adjustable Armrests

Armrests adjust across six dimensions — height, width, depth, front tilt (30°), rear tilt (15°), and 360° rotation — so you can match arm support to typing, mousing, or resting positions without compromise.

• 360° rotation - swivels to match any desk or seating angle
• Front/rear tilt - 30° forward and 15° rear tilt for typing or relaxed positions
• Height, width and depth adjustment - fits a wide range of body types and desk heights

Adjustable Headrest and Extendable Footrest

The 3D headrest adjusts for height, depth and angle to support your head and neck whether you're working or taking a break. The extendable footrest folds out for reclined rest positions and folds away when not in use.

5-Level Backrest and Seat Height Adjustment

The entire backrest — including the lumbar area — slides up and down across 5 levels (6cm / 2.36" of travel), and the seat height adjusts across its own 5 positions, so the chair fits your desk height and body proportions rather than the other way around. Backrest recline runs from 90° to 140° with a tilt lock to hold your preferred angle in place, for anything from focused work to a full break.

Perfect for Long Hours and Larger Body Types

Spencer is built for people who sit for long stretches and want support that adapts with them — whether that's a full workday at a home office desk, a long gaming session, or working from a larger-than-average frame. Supporting users up to 150kg and 200cm tall, with independent 3-step adjustable lumbar support to reduce lower back fatigue, Spencer is suited to Australian home offices and corporate workspaces alike.

Warranty and Support

Every Spencer Ergonomic Chair comes with a comprehensive 10-year warranty covering the frame, base, casters, gas lift mechanism, and all adjustment controls.

Easy Assembly

Spencer ships with clear DIY assembly instructions and all necessary tools included — no additional tools required. Threaded screw inserts and pre-drilled holes keep setup quick and straightforward.
