  • UPGRADED CLASS 4 GAS LIFT CYLINDER: Constructed from thick alloy steel, this Class 4 gas lift is rated for up to 1000 lbs and delivers rock-solid support without sinking or wobbling. Ideal for heavy users and high-traffic kitchens, bars or commercial spaces.
  • SMOOTH HEIGHT ADJUSTMENT: 8.5" stroke piston gives a 19.5"–28" height range, 2" outer tube and 1-⅛" tapered stem. Whisper-quiet lift plus 360° swivel makes it perfect for bar stools, kitchen islands, workbenches or vanity tables.
  • SAFETY CERTIFIED & DURABLE: Validated by BIFMA, SGS and TÜV Rheinland, the cylinder uses premium steel with an anti-burst ring that resists rust, leaks and cracks. Cycle-tested for 50,000+ adjustments to give years of reliable everyday use.
  • EASY TO INSTALL: Usually tool-free. If the old cylinder is stuck, tap lightly with a rubber mallet or pry it out. Insert the new lift into the base, align with the seat mount and press until it clicks. Quick, cheap refresh that makes your stool feel brand-new.
  • AFTER-SALES SUPPORT: Every cylinder is backed by a 5-year warranty against manufacturing defects (excludes misuse). Buy once, enjoy years of steady, worry-free performance.
