{"type":"firestarter.listing","listing":{"id":"lst_8bHed9pK","product_name":"Vyper Big Boy Wide Seat Attachment","category":"Garage","description":" Description\nVyper Chair Accessories\nThe Big Boy is an accessory you may not need but something you may want to have for your Vyper chair. I discovered this while at SEMA and thought it was super comfortable. It provides an additional 6” to your Vyper Chair, which is perfect for those of us who have a wider frame, and like all of the other Vyper products, it was easy to assemble.\nThere’s some versatility to this thing as well. I have the OG Vyper Chair that I have this attached to, and I like that I can roll the chair around where my chest is against the backrest when I’m polishing. The Big Boy provides extra stability where I don’t need to focus on balancing my body so much.\nA few things you need to know: 1) The Big Boy cannot be used on chairs with the Sidekick attachment, and 2) It doesn’t work with the Low Pro.\nWhat You Get\nx1 Vyper Big Boy Wide Seat Attachment\nPlease note that this product includes only the accessory stated in the title and does not include the Vyper Chair itself.\nShipping Information\nThis item is dropshipped from Vyper Industrial in Wisconsin. Shipping is free.\nExpect the lead time for all Vyper orders to be 3-4 weeks.","images":["https://cdn.shopify.com/s/files/1/1239/9256/products/Q4A8531Large.jpg?v=1674851393","https://cdn.shopify.com/s/files/1/1239/9256/products/Q4A8533Large.jpg?v=1688148618","https://cdn.shopify.com/s/files/1/1239/9256/products/Q4A8538Large.jpg?v=1688148618"],"price":195,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:59.978Z"},"share_url":"https://firestarter.network/l/lst_8bHed9pK","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
