See attached for the assembly manual. Read manual in its entirety before assembling the chair. While assembly is simple, it may make it even easier to have someone assist.
Take care when inserting the wooden dowels that connect the seat back to the seat bottom. Be sure to not let the weight of the pieces stress the dowels before the screws are inserted (prop the chair against a wall, or have a partner support it while inserting the screws).
Part E chair leg left and part F chair leg right are as you stand in front of chair looking at it (NOT as you sit in it).
