Answer :
Final answer:
Spring rockers are designed to support a specific number of users, providing benefits to various body joints and offering emotional comfort, partly due to their association with John F. Kennedy.
Explanation:
The seat design of spring rockers should not allow the rocker to be used by more than the intended number of users. This is important for maintaining the structural integrity and safety of the furniture. Spring rockers provide several health benefits, such as promoting movement in the ankle, knees, and hip sockets, and offering support to the shoulder, neck, and head. They became popular in part because of John F. Kennedy, who was prescribed a rocking chair for his bad back. Rockers not only provide somatic comfort but have an emotional appeal as well, which can be just as important for users.
