The "assembly" of the back portion was easy enough for my 140 pound 9 year old Grandson to pick up and put in the slots which was available on the bottom piece.  Very simple but to heavy for me to pick up and do at the age of 82 years.  It fits exactly in the same place where my worn out occasional chair was and now at the curb and fits my back and torso like it was made just for me.  As usual, this is the 3rd high quality purchase I have received from Wayfair and have recommended your Website to all my friends and relatives.
