Every part of a Stealth chair is replaceable and each one is in stock. Find the symptom below and we will point you at the part and the walkthrough.

1. Symptom

   The chair slowly sinks while I am sitting in it

   Usually the gas cylinder has lost its seal, which is the single most common failure on any pneumatic chair and is not repairable.

   Fix Your chair needs a new cylinder.

   Replacement cylinder → Watch the cylinder walkthrough
2. Symptom

   The chair rolls away from me on stage

   Usually The standard 60mm casters are on a tilted or uneven surface. They are best for a flat studio floor.

   Fix Go bigger before you go static. TourMax 4-inch touring casters roll over uneven surfaces rather than skating on them, and every set includes a locking wheel. Full glides are the answer only if you want the chair completely stationary.

   TourMax heavy-duty casters → Compare all caster and glide options
3. Symptom

   The backrest will not stay upright

   Usually The upright adjustment knob has worn or backed out, so the backrest can no longer hold its set height.

   Fix Replace your backrest height adjustment knob.

   Backrest upright adjustment knob → Watch the backrest walkthrough
4. Symptom

   The arm rest has gone loose

   Usually The arm rest knob has stripped or loosened.

   Fix Install a new armrest knob.

   Replacement arm rest knob → See all knobs and levers
5. Symptom

   The seat has come off or makes me feel like im falling out of the chair.

   Usually The seat bushings have worn or broken. They are the sacrificial part in the mechanism, so they are meant to go before anything structural does.

   Fix Replace the bushing set.

   Replacement bushings, set of 4 → Watch the bushing walkthrough
6. Symptom

   The chair will not go high enough for my console

   Usually You are at the top of a standard or touring cylinder. Front of house desks and standing racks often sit above what a normal office chair reaches.

   Fix fit the next height of cylinder. If you are going from a studio to touring cylinder, add a footring so you have somewhere to rest your feet.

   Cylinders → Add an adjustable footring
7. Symptom

   The base is cracked or a caster has snapped off

   Usually The base has taken an impact, usually in transit.

   Fix Install a new base.

   Replacement chair base → See casters and bases
8. Symptom

   The height lever does nothing when I pull it

   Usually Your cylinder underneath it has failed.

   Fix Replace your cylinder

   Cylinder Replacement → Extra Tall
