Abstract: A modular chair including a pair of upper components each having a generally U-shaped configuration. Each upper component has a horizontal segment having opposed ends. The opposed ends each have a rounded segment secured thereto and extending upwardly therefrom in an outwardly angular orientation. A pair of lower components are adapted for coupling with the pair of upper components. The pair of lower components each have a generally U-shaped configuration. Each lower component has a horizontal segment having opposed ends. The opposed ends each have a vertical segment extending upwardly therefrom. Each vertical segment has an arcuate recess formed on upper and inner surfaces thereof. The pair of upper components are receivable between the vertical segments whereby the rounded segments are seated within the arcuate recesses and the horizontal segments are in an abutting relationship in a fully assembled configuration.
