Our armrest pads are designed specifically for Knoll Life fixed armchairs and height-adjustable chairs. Their size and shape (23.5 x 10 cm / 9.25 x 3.93 inches) are identical to the original armrest pads, ensuring a perfect fit. Made of premium PU leather, they are durable, waterproof, and easy to care for, with high-density foam filling for optimal comfort even during long hours of work—say goodbye to arm pain! Installation requires no complicated tools or professional skills; you can easily replace the armrest pads in 5 minutes with just a small Phillips screwdriver, saving you time and effort. Whether your original armrest pads are cracked, faded, or worn, our replacement armrest pads will give your Knoll Life chair a fresh new look. Note: This product is only compatible with Knoll Life fixed armrests and height-adjustable armrests only. Please confirm your chair's armrest model before purchasing (incompatible with 4D/high-performance/multi-directional adjustable armrests). The package includes 1 pair (left + right) of fixed armrest pads and 12 perfectly matching new screws. We are committed to providing high-quality replacement parts for Knoll Life chairs—if you have any questions about compatibility or installation, please feel free to contact us, and we will respond within 24 hours.
