Product Details

A full synchronous task chair built for long working days – Prompt is built around a full synchromatic mechanism with integrated forward tilt, an instant-response tension control wheel with 240° of travel, and a five-position backrest lock. It is specified for office and home-office users who sit for extended periods and want the chair to move with them rather than hold them still.

Adjustment where it matters, without unnecessary complexity – A sliding seat sets seat depth to leg length, the backrest adjusts for height, and seat tilt is included as standard. On the upholstered backs the chair is GS-certified to a 150 kg user weight, placing it well above the typical 110 kg rating of standard office seating.

Key Highlights:

  • GS-certified to 150 kg user weight on the upholstered backs – independently tested, not a manufacturer estimate

  • Instant-response tension control wheel (240°) – tune recline resistance to your bodyweight

  • Five-position backrest lock – more lock points than the four-position mechanisms common at this level

  • Integrated forward tilt – tips the seat forward for focused desk work

  • Sliding seat depth adjustment – standard, not an upcharge

  • Height-adjustable backrest – positions lumbar support to your spine, not the average

Built for people who sit six hours a day or more – Prompt's adjustments are the ones that change posture: seat height, seat depth, backrest height and recline resistance. Cold-moulded polyurethane foam is used on the upholstered seat and backrest, and the upholstery is applied without adhesives.

  • Pneumatic seat height adjustment: 400–540 mm depending on specification, letting you set feet flat with a neutral knee angle

  • Sliding seat depth: 70 mm — clears the back of the knee while keeping full thigh support

  • Height-adjustable backrest: Aligns the lumbar curve of the backrest to your own

  • Adjustable torsion control: A 240° wheel sets how much resistance the recline offers

  • Forward tilt: Opens the hip angle for periods of close, concentrated work

  • Free-flow recline with five-position lock: Move freely, or fix the backrest where you want it

Why it matters

Even a well-engineered chair won't help if it's set up incorrectly — you'll carry the same aches into a new chair. This guide covers the small, high-impact adjustments that fix the cause, not the symptom, so your chair delivers the comfort and support it's built for.

Place any order and we'll email your download link as soon as your order is confirmed. Open it on your phone, tablet or laptop and follow the steps as you set up your chair.

The Apex Ergonomics Pack is available only to Apex Comfort customers — not included when the same chairs are bought from general retailers or marketplaces.
