Abstract
A chair with a disconnectable back so that the back can be moved from its normally upright mounted position relative to the seat to be placed against the seat so as to minimize space to facilitate shipping of the chair. The seat has a pair of receiving cavities located at the back edge of the seat. The back has a pair of protuberances which are to engage with the receiving cavities. The back also includes a spring biased pin assembly that is to deflect when moving of the back between a pair of armrest frames with the spring biased pin assemblies engaging with holes formed within each armrest frame thereby locking in place the back with the seat achieving the normal usage position for the chair.
