Patient Trolley

Narrow wheeled emergency trolley about 2x0.7m, tubular chrome frame with a thin mattress, tilting backrest, iv pole socket, folding side rails and an under-deck equipment tray, with a raised/lowered deck height knob.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
