Chair exploded learning board

Create a clean instructional illustration of an original adjustable desk chair shown in an exploded vertical view. Align the headrest, curved back shell, padded seat, arm supports, center column, and five-wheel base along one central assembly axis, leaving enough space to distinguish each component. Use pale turquoise upholstery, muted coral plastic, warm yellow padding, and neutral gray metal so materials are easy to compare. Render from a slightly elevated three-quarter angle with soft studio shadows on a white background. Add only short labels for SEAT, BACK, ARMS, and BASE, connected by thin straight leaders. Avoid dimensions, engineering tolerances, hidden internal mechanisms, and unsupported assembly instructions.
