This appears to be good quality for an inexpensive seat. I mounted it on my Lion Liftall forklift with a little modification. I had modified my seat base once before for the last seat that I had installed on it by welding a couple pieces of angle iron to it to make it wider. To mount this seat, I just had to drill new holes in the angle iron to fit the new bolt pattern. There are four 5/16" studs on the bottom of the seat set at 11" front to back and 10 3/4" side to side. The seat came with washers, lock washers and nuts for each of the studs. It has hardware on it to allow the seat position to be moved front to back several inches. It's very comfortable and the vinyl is flexible and appears to be good quality. It should last for at least a few years without cracking and tearing.
