Ergonomic Support: Designed with a contoured backrest for lumbar comfort and a thick, high-density foam seat.
Adjustability: Typically includes a pneumatic gas lift for height adjustment and, in some models, seat depth adjustment to grow with a child.
Stability: Built on a five-point nylon or plastic base with swivel casters for easy movement. Some versions for younger children feature gravity-locking wheels that stay still when weight is applied.
