1. A foldable seat comprising:
a vertically extending support arrangement for being mounted to a surface and having a vertical axis and a horizontal plane, the vertically extending support arrangement comprising opposite top and bottom ends along the vertical axis, and a geometric outer perimeter in the horizontal plane having a perimeter size and defining opposite front and rear sides and opposite lateral sides;
a seat member being removably mounted to the top end of the vertically extending support arrangement to overly the top end of the vertically extending support arrangement;
a pivot assembly mounted to the vertically extending support arrangement at the top end thereof for pivoting about a pivot axis parallel to the vertical axis;
the vertically extending support arrangement comprises four spaced apart legs positioned about the pivot axis, the four spaced apart legs comprising one pair of adjacent legs thereof positioned at the front side and another pair of adjacent legs thereof positioned at the rear side;
a back structure vertically extending from the top end of the vertically extending support arrangement, the back structure comprising a pair of spaced apart vertical back posts defining respective top free ends thereof, each of the pair of vertical back posts being contiguous with a respective one of the pair of adjacent legs thereof positioned at the rear side, the back structure comprises a removable top horizontal backrest member mountable to the top free ends of the vertical back posts,
wherein pivoting the pivot assembly provides for moving the vertically extending support arrangement between folded and unfolded positions respectively decreasing and increasing the perimeter size;
wherein when the vertically extending support arrangement is moved to the folded position, the pair of adjacent legs at the front side are moved closer together, the pair of adjacent legs at the rear side are moved closer together, and the pair of spaced apart vertical back posts are moved closer together;
the pivot assembly comprising:
a cylindrical hinge body having a vertical length between top and bottom ends thereof and defining the pivot axis; and
four connectors, each of the four connectors having one end thereof being integral to a respective one of the legs and an opposite end thereof being integral to the cylindrical hinge body along the full vertical length of the cylindrical hinge body, each one of the four connectors being diagonally opposed to another one of the four connectors and being integral with the cylindrical hinge body therebetween thereby blocking any relative pivoting movement between the diagonally opposed connectors about the pivot axis, each of the four connectors defining a longitudinal top end thereof extending between the respective one of the legs and the cylindrical hinge body and being substantially flush with the top end of the cylindrical hinge body, the top ends of the four connectors and the top end of the cylindrical hinge body providing for receiving the seat member when the vertically extending support arrangement is in the unfolded position, the cylindrical hinge body being configured to provide a respective space between the pair of adjacent legs at the front side, between the pair of adjacent legs at the rear side, and between the pair of spaced apart vertical back posts when the vertically extending support arrangement is in the folded position;
wherein when the seat member is mounted to the vertically extending support arrangement and/or when the backrest member is mounted to the vertical back posts, the pivot assembly is blocked from pivoting.
