ABSTRACT:
A Single-hand height adjustment mechanism of a highchair includes an operating unit handled with a single hand, and a locking unit connected with the operating unit. The operating unit uses simple movement, such as handle pressing or button pulling, to pull adjustment wires. The adjustment wires then activate or release the locking unit. Therefore, the seat can be adjusted to higher or lower positions with the use of a single hand.
