This chair was easy to assemble and looks perfect on our small deck.  The listing says it is made of plastic, which it is but it’s not the cheap molded big box kind.  It definitely is solid plastic slats assembled like a wood Adirondack. Having said that, DO NOT assume it is Trex or polywood decking material. I have 4 Polywood Adirondack chairs  on the deck at our lake house, purchased elsewhere for 249 each and they are much heavier (overall weight of 55lbs each compared to this one which is 30lbs) so they don’t blow in strong winds that we occasionally have. This one, I think might if it was on an exposed patio in a high wind area. On the balcony it is going to be fine.  I do love the ability to leave it out year round, as we get snow and many of our outdoor items must be stored away in winter.
