Buying Guide
Key considerations for compressed gas cylinder replacements include load capacity, travel length, and mounting compatibility. Identify your chair’s base diameter, inner bore, and mounting hole spacing before purchasing.
- Capacity matters: choose a model that supports your weight plus typical occupant loads. Higher capacity reduces the risk of sag and extends chair life.
- Stroke and sit-stand range: longer strokes allow more seat height range, but verify the chair’s hydraulic path and clearance under the desk.
- Uniform sizing: most replacements use standard outer diameters (2 inches) and inner diameters (1.1 inches). Confirm with your chair model to avoid mismatches.
- Noise and smoothness: look for 360-degree rotation and low-friction operation for quiet environments.
- Installation and compatibility: check mounting screws, piston shaft diameters, and whether your chair uses a one-piece or modular lift assembly.
