About this item

This is a replacement gas lift cylinder for office chairs that sink or won't hold height. It compresses to 11.69" and expands to 17.2", giving a 5.5" stroke range, with a 2" outer cylinder diameter and 1-1/8" piston shaft that fits most standard chair bases, including Herman Miller Aeron — but not IKEA or some other brands. Built from steel and rated to BIFMA/ANSI Class 4 standards, it supports up to 1000 lbs. Measure your current cylinder before ordering to confirm fit.

• Compressed length 11.69" (297mm), extends to 17.2" (437mm) — 5.5" of stroke to raise your seat higher
• Outer cylinder diameter 2" (50mm), piston shaft 1-1/8" (28mm) — check these measurements against your current cylinder before ordering
• Steel build rated Class 4 / BIFMA-ANSI standard, holds up to 1000 lbs
• Fits most standard office chairs, including Herman Miller Aeron — not compatible with IKEA chairs or some other brands
• Swaps in easily to fix a sinking seat, with full 360° swivel once installed
