Adjustable Backrest for Vyper Chairs The Vyper Adjustable Backrest is the next level of comfort for buyers who live in the chair. The stock backrest is built right, contoured to the lumbar, and works for most buyers exactly as designed. The Adjustable Backrest goes further with a taller height range, the ability to lean back up to 10 degrees, and fine-tune positioning that matches the support to your specific body and the way you actually work. Reviewers tell us this is the upgrade that turns the chair from "comfortable" into "I never want to get up." Half of customers add it during initial chair configuration. The other half come back for it after months in the chair, deciding they want to dial in the backrest position even further. Compatible with the Robust Steel Max and Elevated Steel Max models, and pairs well with the Big Boy and Sidekick Attachments. Features: 📏 Taller Height Range: Extends the adjustable height window past the stock backrest so taller buyers can position lumbar and mid-back support exactly where they need it. 🎯 10° Recline: Leans back up to 10 degrees, opening the hip angle and reducing lower-back pressure during long bench sessions. 🔧 Fine-Tune Positioning: Multi-axis adjustment lets you match the backrest to your specific body and the way you work, rather than forcing your posture to the chair. 🛡️ Robust Steel Compatibility: Fits the Robust Steel Max and Elevated Steel Max chair models, and pairs with the Big Boy and Sidekick Attachments for a fully built-out Vyper. *THIS ACCESSORY IS NOT ELIGIBLE FOR ANY DISCOUNTS OR SALES*
