Design a full 3D CAD model of a Semi-Reclined Ergonomic Work Recliner Chair intended for long-hour IT professionals (8–10 hours/day). Purpose: The chair must allow working on a laptop and mouse while semi-reclined, reducing spinal load, neck strain, and lower-back pain. Design Constraints: Made in India, low-cost prototype Suitable for local fabrication using: MS steel square pipe frame (1” x 1”, 2–2.5 mm thickness) Plywood panels (12 mm) High-density PU foam No imported recliner mechanisms Fixed-angle mechanical recline (slot-and-lock system) Chair Geometry: Seat height from floor: 420–450 mm Seat depth: 480–520 mm Backrest height: 700–750 mm Base footprint wide enough to prevent tipping in recline Load capacity: 120 kg Recline System: Backrest recline angles: 120° (primary work recline) 135° (relaxed work) 150° (rest / semi-sleep) Use a manual slot-and-pin locking mechanism No gas lift or hydraulic system Ergonomic Features: Dynamic lumbar support (curved backrest profile) Neck / cervical support with detachable headrest Pelvic tilt support integrated into seat pan Foam thickness: Seat: 80–100 mm (high density) Back: 50–70 mm Work Functionality (Critical): Right-side arm-mounted foldable work tray Tray size: Laptop surface: approx 350 x 280 mm Mouse area extension Tray must be: Height adjustable Angle adjustable Stable in reclined positions Foot Support: Hinged or fixed footrest Footrest angle aligned with recline Knee angle approx 110–120° in work posture Armrests: Fixed armrests Height aligned to avoid shoulder elevation Wide enough to support forearms during typing Output Requirements: Full assembled 3D model Exploded view showing: Steel frame Recline mechanism Seat + back panels Work tray arm Side view showing all recline angles Dimensioned drawings suitable for fabrication Neutral industrial design (no luxury styling) Design Philosophy: This is a productivity + health device, not a gaming chair or luxury recliner. Prioritize ergonomics, stability, manufacturability, and cost control over aesthetics
