Seems decent quality.
Kind of a pain to assemble. The parts don't sit in a good position to get screws started.Tool is included to assemble. They've included washers the instructions don't mention. I used mine where the seat mounts to the bracket.

 TIP: After getting parts out of box, close it back up (right side up) and use it as a workbench to assemble the seat portion. Place the back, on top of the box, bolt holes up, and then hold armrest up while starting screws. When both armrests are installed place the seat upside down on the box and then hang the back/arms off of it to finish. Much easier than having pieces flopping around.
