摘要： A modular furniture assembly is disclosed herein. The assembly includes a base, an upright member, and one or more connector plates configured to selectively couple a bottom portion of the base to a bottom portion of the upright member. The base and the upright member are sized and configured in a particular defined spatial relationship where the length (X) of the base is substantially equal to the sum of the width (Y) of the base and two times a dimension (Z) which is the width (Z1) of the upright member or a separation distance (Z2) between adjacent receiving holes of the base and upright member. Thus, X is substantially equal to Y+2Z.
