This looks like a rather stupid design that makes it difficult to stand back up.
You might just be trolling. If not, Adirondack chairs have a long history.
I wish it had a “curved” back, rather than flat. Although i am still tempted to buy a couple for around the fire pit and leave them out all year long.
These rot faster than wood if you leave them out in any sort of sunlight. Plastic is horrible in the sun. I’ve almost cut my hand open grabbing plastic buckets that have been left outside for only a season. These do better in rain, and generally all around better than wood if taken care of and kept out of the elements. But that is the same for wood - take care of it and it will last.
A little more expensive, but also a nicer design… IMO.
