Abstract: An upright child high chair may include a seat configured to support the weight of the child and maintain an upright body position of the child. The seat may include two symmetrically opposed apertures for accommodating the child's legs extending in the upright body position below the seat. The high chair may further include a base structure attached to the seat and extending downward from the seat. A platform may be attached to the base structure and may be located below the seat. The platform may be configured to deflect from a resting position in response to a force applied to the platform by the child while the seat continues to substantially support the weight of the child.
