Designed in MunichSynchronised tilt mechanismClass 4 gas liftBS 5852 flame retardant
Built for long working days
Adjustable headrest
Height and angle both adjust, so the headrest meets your neck instead of pushing your head forward.
Lumbar support that moves
5 cm (2″) of height adjustment. Set it to your lower back rather than hoping the chair happens to fit.
Reclining mesh back
Lean back and lock the backrest between 90° and 120°. Focus upright, relax reclined.
Features
Breathable mesh back
Breathable mesh backrest keeps the air moving — even in summer.
Height-adjustable lumbar support
Every M3 comes with a lumbar support that adjusts 5 cm (2″) in height, so it sits where your back actually needs it.
Height-adjustable seat
The seat moves 10 cm (4″) in height, between 48.5 and 58.5 cm (19.1″–23.0″) — adjust it to your body, not your desk.
Adjustable headrest
On every M3 the headrest adjusts in height (11 cm / 4.3″) and angle — comfortable thanks to the breathable mesh.
Synchronised tilt with reclining backrest
Seat and backrest move together as you lean back, with the tension set to your body weight. On the Comfort the backrest locks in four positions between 90° and 120°.
Height-adjustable armrests
2D armrests with soft PU pads, height-adjustable on both configurations.

VALKENSTOL M3 — the all-rounder with a bit of design to it
The M3 is the model people pick when they want ergonomics that hold up over a full working day without the chair announcing itself in the room. Two configurations, same design, different levels of adjustment.
What makes a good office chair for a full working day?
Eight hours in one chair exposes everything it gets wrong. The M3 covers the parts that matter: a lumbar support you can set to your own back, a headrest that adjusts in height and angle, a synchronised tilt mechanism with tension adjustment, a mesh back that reclines and locks, and a moulded foam seat that keeps its shape instead of flattening after six months.
Who is the M3 for?
Designed for people between roughly 1.60 m and 1.90 m (5’3″–6’3″) with a recommended user weight of up to 120 kg (265 lbs); maximum load capacity is 150 kg (330 lbs). Built for full-time desk work with 8 hours or more of sitting a day.
Classic or Comfort?
The Classic covers the ergonomic basics — 2D armrests, height-adjustable lumbar support, backrest locking in one position. The Comfort adds 5 cm (2″) of seat depth adjustment and a four-position backrest. Pick by how long you sit, and how much you like adjusting things.
Who we are
VALKENSTOL is a design studio for ergonomic office chairs based in Munich, founded by Dr Stephan Braun because he couldn’t find a decent chair himself. Our chairs are designed in Munich and shipped from Germany.
