This is a good value alternative to better known brands which cost over A$1k delivered. I bolted it to my zero turn mower and it transforms the ride. It does not have an operator presence switch, I'm investigating using a pressure switch designed for car seats, it cost under $10 and can slide between foam and seat base. Work in progress. Packaging is a bit rudimentary but the seat is not flimsy apart from the arm rests. Upon unpacking, don't worry if the seat suspension carriage appears locked up, as once installed, the internal cams sort themselves out. The seat belt is useful if your vehicle has a ROPS.
