A chair that is reconfigurable between a folded and an unfolded configuration includes a first leg having an intermediate portion located between a first end and an opposite second end of the first leg and a second leg having an intermediate portion located between a first end and an opposite second end of the second leg. The intermediate portion of the second leg is pivotally connected to the intermediate portion of the first leg. A support member has a first end pivotally connected to the first leg and an opposite second end. A seat frame has a first portion pivotally connected to the second end of the support member and a second portion pivotally connected to the second end of the second leg. The second end of the support member is adjacent the first end of both the first and second legs in the folded configuration.
