About this item

  • WIDE HEIGHT ADJUSTMENT RANGE: A wide lifting range of 150mm (5.9") with a minimum height of 11.8" and a maximum height of 17.7". Whether adjusting the height of the desk or customizing it for multiple users, the office chair gas cylinder always ensures the ideal sitting position.
  • COMPATIBILITY: With an outer diameter of 50mm, a piston diameter of 28mm and a rod of 45mm, this office chair cylinder replacement fits most standard office chairs that accept a 2" mounting hole. Please check the size to ensure compatibility.
  • RELIABILITY AND SAFETY: Lift up your office chair with this Class 4 hydraulic cylinder certified by SGS and BIFMA. Constructed of thickened steel with an explosion-proof and pressure reduction design, capable of withstanding up to 1,000 pounds without wobbling, losing or malfunctioning, it is the ultimate alternative to office chair replacement parts, which ensures you long-term peace of mind.
  • SILENT AND ULTRA SMOOTH LIFTING: Thanks to precision seals and pneumatic dampers, height adjustments are silent and the 360° rotation quiet. No squeaks, no shots, just smooth movements and a quieter workspace.
  • EASY INSTALLATION: Simply remove the protective cap (if applicable), remove the old pneumatic lifter (we recommend the use of a rubber hammer), insert the new office chair piston and you're done: no additional screws or complicated steps are required.

How can I check whether a product will fit my workspace?

Please review the dimensions, weight capacity, mounting requirements, and available clearance listed on the product page. For desks, chairs, cabinets, and mounted accessories, we recommend measuring your room, doorway, desk surface, and installation area before ordering.

How do I know whether an electronic accessory is compatible with my device?

Check the product page for supported device models, port types, operating systems, voltage, plug type, monitor size, weight limits, or printer compatibility. Contact us before purchasing if you are uncertain about compatibility.

Do office furniture products require assembly?

Many desks, chairs, cabinets, stands, and shelving products require some assembly. Assembly requirements and included hardware vary by product, so please review the individual product description and instructions before purchase and use.

How much does shipping cost?

Why did only part of my order arrive?

Products may be stored in different warehouses or shipped in multiple boxes. As a result, items and furniture components may arrive separately with different tracking numbers. Please review all shipping confirmation emails before reporting an incomplete delivery.

Can I change or cancel my order?

Please contact us as soon as possible after placing your order. We will make a reasonable effort to update or cancel an order that has not entered processing or shipment, but changes and cancellations cannot be guaranteed once fulfillment has begun.

What is your return policy?

Eligible products may generally be returned within 30 calendar days of delivery, subject to our Return & Refund Policy. Items should be unused, unassembled, uninstalled, and returned with their original packaging, hardware, manuals, and accessories. Contact us for authorization before sending a return.

What should I do if my product arrives damaged, defective, or incomplete?

Contact us within 7 calendar days of delivery whenever reasonably possible. Include your order number, a description of the issue, and clear photographs of the product, packaging, shipping label, and affected components. Please retain all packaging until the claim has been reviewed.
