Extra Wide Seat and Tall Backrest Design
Three measurements do the work. Seat width, arm to arm, is where a standard model tops out around 20–22 inches and a bigger one starts near 23. Back height climbs so a taller sitter's head lands on the headrest instead of above it. Weight capacity rises because the frame is reinforced and the reclining hardware is heavier gauge, not because a label says "big and tall."
