Why does the rocking chair I made not rock smoothly?

There could be several reasons why your rocking chair doesn't rock smoothly. First, check the curve of the rockers; if they're uneven or too steep, it can affect the motion. Additionally, ensure that the chair is level on the floor and that all joints are properly fitted and secured. Lastly, inspect for any obstructions or friction points, such as rough surfaces or debris, that might hinder movement.
