Foldable leisure chair

Abstract

A foldable leisure chair has two side frames, a backrest unit connected to the side frames, and two armrest members connected respectively to the side frames. Each armrest member has a pivot portion connected pivotally to a corresponding side frame, an armrest portion extending from an end of the pivot portion, an extending portion extending from an opposite end of the pivot portion, and an abutment portion extending from the extending portion and abutting against a bottom side of the corresponding side frame. Each armrest member is pivotable between an unfolded position, where the armrest portion thereof is in front of the extending and abutment portions and is away from the corresponding side frame, and a folded position, where the armrest portion thereof is behind the extending and abutment portions and is close to the corresponding side frame.
