About This

• 【Easy Compatibility Check】 Flip your seat cushion to check for pre-drilled holes or a metal mounting plate. Measure the hole spacing to ensure it matches the standard 204×145mm pattern. Confirm your gas lift size is 1.1" (28mm) in diameter and that your seat base supports M8 screws (20–25mm length).
• 【Standard Size Compatibility】Designed to fit most office chairs with a screw mounting hole spacing of 8" (L) x 5.7" (W). Compatible with standard Dia. 28mm (1.1-Inch) tapered gas lift cylinders for seamless integration. Ideal for replacing broken mechanisms in office, gaming, or home chairs. Please verify your chair’s mounting measurements before purchase.
• 【Dual-Lever Tilt Mechanism with Ergonomic Angle Control】 Featuring a dual-lever design for advanced ergonomic control. Lever 1 controls height adjustment and backrest lock/unlock. Lever 2 locks or releases recline angle — adjusting seat cushion from 3°–10° and backrest from 87°–106°. Smooth infinite tilt tension control via hand knob. Seamlessly switch between focused work and relaxed recline without constant readjustment.
