A Full Fowler bed is an adjustable hospital bed with independently controlled head and knee sections, allowing for positions from fully flat to an upright sitting posture (head to 90°, knees raised), crucial for patient comfort, improved breathing, digestion, circulation, and easier care for those with respiratory issues, post-surgery recovery, or limited mobility. Key features include a 4-section top, manual cranks or electric motors, side rails, castors (wheels), and durable frames, designed for versatility in hospitals and home care.
