I understand that you want to purchase a replacement part for your Razer Iskur. You can submit a ticket through this link.
Once there, navigate to "Lifestyle products" > "chairs" > enter your serial number, and then submit your request. Our Support Team will then be able to assist you with your gaming chair spare part request.
Alternatively, you can send me a PM together with your device’s serial number, and I can help you initiate a support ticket.
