FLYBIRD Adjustable Weight Bench WB5 — 363 kg Capacity, ASTM-Certified Foldable 30" Backrest

The FLYBIRD WB5 is a heavy-duty, ASTM-certified adjustable weight bench that supports up to 800 lbs and folds compactly for small-space home training.

This WB5 bench combines a fortified steel frame, an extra-long 30-inch backrest, and a fast-release spring-lock system to deliver reliable support across incline, decline, flat, and upright positions. Designed for both serious lifters and home fitness enthusiasts, the bench balances stability, multi-angle adjustability, and space-saving convenience while meeting industry safety standards.

How versatile is the WB5 for different workouts?

The WB5 offers wide-ranging angle options so you can target chest, shoulders, back, and core from multiple planes. Its -30° to 90° range plus a 30-inch extended backrest make it suitable for bench press, shoulder press, decline work, and seated isolation moves.

• 144 distinct position settings for precise positioning
• -30° decline and 90° upright lock for specialty movements
• 30-inch backrest and 15.7-inch seat pad for full-body support
• Flat, incline, decline and upright configurations covered

Is the WB5 sturdy enough for heavy lifting?

The structure is built with an elongated thickened steel frame and reinforced dual-triangle geometry for exceptional load distribution. ASTM certification and an 800 lb rated capacity mean the bench is engineered for high-load safety and long-term use.

• ASTM-certified frame construction for verified safety
• Double-locking mechanism to secure angles under load
• Dual-triangle support improves stability and reduces flex
• Designed for both beginners and advanced lifters

How fast and simple is adjustment and storage?

A self-rebound spring-lock enables quick 1-second angle changes for both backrest and seat, so you can move between sets without interrupting your session. When workouts finish, the bench folds in three steps to shrink its footprint by up to 80%, making storage practical for apartments and compact home gyms.

• Spring-lock quick-adjust for rapid angle changes
• Three-step fold-down for small-space storage
• Requires only about 9.06 inches width when folded
• Lightweight 28.5 lb build for easy portability

What comfort and fine-tune features help training quality?

The WB5’s elongated cushions support your head, neck, and spine during heavy lifts to encourage proper form and reduce unwanted arching. It also includes an adjustable leveling footpad to keep the bench stable on uneven floors and a generously sized seat for comfortable positioning under heavy loads.

• 30-inch backrest and 15.7-inch seat pad for improved form
• Adjustable leveling footpad for stability on imperfect floors
• Padding geometry designed to limit lower-back arch during presses
• Durable upholstery and robust seams for frequent use
