MATCH High-Back Ergonomic Office Chair

The MATCH High Back is an adjustable ergonomic office chair designed for focused desk work, shared workstations, management offices and home offices. Instead of holding every user in one fixed position, it provides multiple adjustment points: a height-adjustable lumbar support, height- and angle-adjustable headrest, two-stage sliding seat, 4D armrests, tilt-tension control and a choice of locking mechanisms. The backrest also folds flat and can be tucked away under a sit-stand desk when raised, which suits shared workstations or meeting rooms where floor space needs to be freed up. These controls allow the chair to be configured around the user, desk and task.

For organisations comparing an office chair in Hong Kong, MATCH is available in silver-frame and black-frame versions, with an any-angle lock mechanism that lets you lock the backrest at any angle, plus an optional footrest. A high-density moulded-foam seat, waterfall front edge, mesh backrest and 660 mm five-star base balance everyday support, ventilation and stability. Optional mechanisms and finishes allow a project team to specify different chairs for individual workstations, shared desks or executive settings while keeping a consistent product family.

An ergonomic chair should be selected for fit, adjustability and intended use—not simply for the number of controls. Review the MATCH dimensions, configuration table and adjustment guide below, then contact Offmax to confirm the correct model number, available options, colour choices, stock availability, delivery arrangements, warranty coverage and pricing.

MATCH's Full-Spine-Support Design Philosophy

MATCH starts from a different design question: instead of supporting one part of the body, can a chair support the whole spine? Coordinated support across the head, neck, shoulders, back and sacrum lets the spine settle back toward a neutral position rather than being held at a single fixed point. The synchronized-tilt base is built to encourage a slightly reclined sitting posture, which keeps the body gently active rather than locked into one static position for hours. A study found that a slightly reclined posture can reduce disc pressure by around 50% compared with sitting upright, which is part of the reasoning behind this approach to seating.

65 mm Height-Adjustable Lumbar Support
MATCH includes a lumbar support with 65 mm of vertical adjustment. This lets the user position the support around the natural inward curve of the lower back rather than relying on a fixed pad. Start with the pelvis close to the backrest, then move the lumbar support until it feels even and comfortable. It should support the lower back without creating a concentrated pressure point or pushing the body forward.
The silver-frame version uses a black lumbar support within a silver frame, while the black-frame version uses a black frame and height-adjustable support. For hot-desking or offices where several people use the same chair, the ability to reset the lumbar position is more useful than a one-size-fits-all profile.

Adjustable Headrest: 70 mm Height, 90 mm Depth and Dual 80° Rotation

The headrest can be raised or lowered through 70 mm, slides forward and back through 90 mm, and adjusts through two independent 80° rotations — an 80° self-rotation of the pad and an 80° arm-rotation of the support arm. The pad is wider than many competing designs, so depending on the seated position, it can support the head, neck, shoulders and upper back together as part of MATCH's full-spine-support concept. This helps users of different heights position the headrest for upright work, reading or reclined sitting. A suitable setting should meet the back of the head or the area that needs support without forcing the head forward. Recheck the headrest after changing the backrest angle, because a setting that works upright may not feel right when reclined.

Two-Stage Sliding Seat and Waterfall Front Edge

Seat depth affects how much of the thighs are supported and how much space remains behind the knees. MATCH provides a two-stage sliding seat-depth adjustment, allowing the seat position to be adapted for different leg lengths. 
The front of the high-density moulded-foam seat has a waterfall profile. When the seat depth and height are set correctly, the thighs should feel supported while the front edge avoids pressing into the back of the knees. The cushion should not be treated as a substitute for movement; users should still change position and stand periodically during extended desk work.

4D Adjustable Armrests for Different Desk Tasks

MATCH uses black 4D adjustable armrests, with 100 mm of vertical travel, 50 mm of front-to-back travel, 20 mm of lateral travel and 40° of rotation. The black-frame specification also lists black PU arm pads, while the silver-frame series can be specified with leather-covered arm pads as an upgrade. Multi-directional armrest adjustment is useful when moving between keyboard work, reading, calls and other desk tasks.
Set the armrests so the forearms can rest naturally and the shoulders remain relaxed. They should not be so high that the shoulders rise, or so wide that the elbows move away from the body. Also check that the armrests do not prevent the computer chair from moving close enough to the desk.

Synchronized Tilt, Tension Control and Locking Options

MATCH uses a Bio-Antagon synchronized-tilt mechanism that mimics the body's natural movement, letting the backrest recline anywhere from 103° to a maximum of 135°, with lock available at any angle in between. Releasing the lock brings the backrest slowly back to an upright position rather than snapping it forward. A study found that a slightly reclined posture can reduce disc pressure by around 50% compared with sitting upright, which is part of the thinking behind this range. Tilt tension is also adjustable. Different The MATCH chair features an any-angle lock, allowing you to secure the backrest at any angle within its recline range. The backrest starts at 103° and reclines up to 135°, so you can adjust and hold your preferred position for working or resting.

For added comfort during breaks, the optional footrest version offers a wider recline range of 103° to 145°, allowing you to lean further back with your legs supported.
H3:Stable Base, Gas Lift and Frame Choices

Silver-frame models are listed with a Class 3 #100 silver gas lift, silver colour backrest frame, 660 mm silver aluminium five-star base and black nylon castors. Black-frame models are listed with a Class 3 #100 black gas lift, black colour backrest frame, 660 mm black nylon five-star base and black nylon castors. A polished or matt-black epoxy-powder-coated aluminium base is available as an upgrade for the black-frame series. All gas lifts have passed Bifma safety testing and German DIN4550 Class 3 safety testing. The five-star base carries a static load rating of 1350 kg and an impact load rating of 136+ kg, and is fitted with quiet PU castors rated for 130 kg static load and tested through 100,000 fatigue cycles.

The five-star base provides a broad support footprint, but floor type and movement should still be considered. Confirm that the selected castors are suitable for the actual flooring and that users have enough clearance to turn, move and recline safely.

Dimensions, Materials and Colours

The mesh-back and fabric-seat MATCH versions are listed at 660 mm wide, 660 mm deep and 960–1,045 mm high, with a seat-height range of 440–530 mm. The high-back leather version is listed at 660 mm wide, 660 mm deep and 1,125–1,215 mm high, with a seat-height range of 440–530 mm. These are product dimensions; the usable footprint will be larger when the chair is turned, reclined or fitted with an extended footrest. The optional footrest measures 360 mm wide by 460 mm long, sized for a midday rest or for stretching the legs during the workday.

Available fabric references shown on the page are SPC001 Black, SPC002 Grey, SPC003 Green, SPC004 Blue, SPC005 Dark Grey and SPC006 Orange. Mesh references are MN3001 Black, MN3002 White and MN3003 Grey. Screen colour, material batch and configuration compatibility can vary, so commercial orders should be confirmed against a physical sample or current swatch where colour matching matters.

Before selecting this office chair for a Hong Kong home or compact workplace, measure the desk height, under-desk clearance, door and lift access, circulation route and the space needed behind the chair. Allow extra room for the 660 mm base, castor movement, recline and any footrest extension.

How to Adjust the MATCH Computer Chair

• Set the seat height. Sit back and place both feet on the floor or on a stable footrest. The thighs should feel supported, and the shoulders should remain relaxed when the hands are at the keyboard.
• Set the seat depth. Keep the pelvis close to the backrest and slide the seat until it supports the thighs without pressing against the backs of the knees.
• Position the lumbar support. Move the 65 mm height-adjustable support to the lower-back curve. Choose the position that feels supportive without a hard pressure point.
• Adjust the armrests. Support the forearms while keeping the shoulders down. Check that the chair can still approach the desk and that the arm pads do not interfere with keyboard or mouse use.
• Adjust the headrest. Set the height and angle for the intended upright or reclined position. Avoid a setting that pushes the head forward.
• Test the tilt tension and lock. Start with controlled resistance, then test the available lock positions. Confirm that the selected model behaves as expected before regular use.
• Review the whole workstation. Chair adjustment cannot compensate for a monitor that is too high or low, a keyboard that is too far away or a desk that forces the shoulders upwards.

Hong Kong Labour Department guidance on computer workstations supports using a stable chair with adjustable seat height, an adjustable backrest and adequate lower-back support. It also recommends a suitable footrest when the feet cannot rest comfortably. Even with a well-adjusted ergonomic office chair, avoid staying in one posture throughout the day; stand, stretch and change position regularly.

Who Is the MATCH Office Chair Designed For?

MATCH can suit employees who spend substantial time at a computer, managers who want a high-back design, hybrid workers setting up a home workstation and organisations fitting shared or assigned desks. Its range of lumbar, headrest, seat-depth, armrest and tilt adjustments is especially relevant when the user needs more configurability than a basic fixed office chair.

For shared workstations, the controls must be easy for each person to reset. Provide simple adjustment instructions near the desk and include chair setup in workstation onboarding. For individual users, test the relationship between the chair, desk and monitor rather than judging the chair in isolation.

For corporate procurement, specify the user-height range, expected daily use, workstation dimensions, quantity, preferred colour, flooring, delivery location and required date. Ask Offmax to record the complete SKU and every upgrade on the quotation. This reduces ambiguity between silver and black frames, locking mechanisms, footrest versions and base finishes.

Frequently Asked Questions About MATCH

1. Is MATCH an office chair, computer chair or ergonomic chair?

It can be described as all three, but each term explains a different aspect. MATCH is an office chair intended for desk settings, a computer chair suited to screen-based work, and an ergonomic chair because it provides adjustable lumbar support, seat depth, armrests, headrest and tilt controls. “Ergonomic” does not mean one setting will fit every user; the chair must be adjusted to the individual and workstation.

2. What is the difference between a standard office chair and an ergonomic office chair?

A standard computer chair may only provide basic seat-height and recline functions. MATCH is designed around the concept of full-spine support, with a multi-directional head and neck rest, height-adjustable lumbosacral support, 50 mm + 50 mm two-stage seat-depth adjustment, 4D armrests and the Bio-Antagon biomechanical synchronized-tilt mechanism. These adjustment points support different working, slightly reclined and resting positions, allowing users to configure the chair around their body dimensions and sitting habits. Suitability will still depend on the individual user, desk setup and actual sitting experience.

3. Is MATCH suitable for long working hours?

MATCH is designed around full-spine support and flexible adjustability. The head and neck rest, lumbosacral support, seat depth, armrests and synchronized-tilt mechanism can all be adjusted to help users change sitting positions during extended computer work. However, even with an ergonomic chair, users should still stand, stretch and change posture regularly rather than remaining in the same seated position for prolonged periods.

4. How does the MATCH any-angle locking mechanism work?

MATCH uses the Bio-Antagon biomechanical synchronized-tilt mechanism, allowing the backrest to move with the user and provide continuous support while reclining. The backrest can be adjusted within approximately 103°- 135° and locked at any preferred angle within this range, giving users greater flexibility to switch between working, slightly reclined and resting positions.

5. Does every MATCH chair include a footrest?

No. The footrest is an optional feature and measures approximately 360 mm wide by 460 mm long. It can be used when reclining or when users want additional support while stretching their legs. Please confirm with us whether the selected MATCH model and configuration support the footrest.

6. What safety and durability specifications does MATCH have?

The MATCH gas lift has passed BIFMA safety testing and the German DIN 4550 Class 3 safety test. The five-star base is specified with a static load capacity of over 1,350 kg and an impact load capacity of over 136 kg. The PU castors have also passed a 100,000-cycle fatigue test.

7. What should I measure before buying an ergonomic chair in Hong Kong?

Besides desk height and under-desk clearance, check the chair width and seat depth, the space required for reclining, castor movement and any additional clearance needed if a footrest is selected. If the office uses height-adjustable desks, the MATCH foldable backrest can also be considered when planning storage beneath the desk. Check in advance whether the folded chair can fit comfortably within the available under-desk space.

8. Can several employees share the same MATCH ergonomic chair?

Yes. MATCH offers multiple adjustment points, including seat height, two-stage seat depth, lumbosacral support, 4D armrests, head and neck rest, and synchronized tilt, allowing different users to readjust the chair to suit their body dimensions and preferred sitting position. For shared workstations, users should reset the key adjustments before use to ensure appropriate support and comfort.
