While the piece in the end is sturdy and comfortable, putting it together was a nightmare. If I hadn’t already spend over 2 hours putting it together I would have shipped it back.-None of the piece of labels, so it’s a crap shoot if you got the right piece on the right side…and yes it makes a difference if you are to use C1 on the right and C2 on the left.-Holes are not drilled correctly so tightening the screws is quite difficult. Needed to lubricate almost all of the screws to get them tightened.-The kicker is the metal piece that connects the bottom mesh seat is 3/8” of an inch too short. No matter how much bending, pushing or pulling, it was impossible to get he holes to line up so you can screw the bar to the chair. I had to weld an additional piece of metal to the bar and drill my own hole to get this piece to fit. So unless you have a welder at home, I would skip this item.UPDATE .....For a higher priced item that is supposed to be weather resistant, ot one weekater and some of the screws are already rusting. I'll be lucky if the lounger lasts a year. Too bad, very comfortable, but definitely not worth the money or the time it took to put it together.
