Description says rated for 1000lbs. Step has sticker for max 500lb load.I am a 300lb plus guy. Platform has some flex when loaded but still feels ok to stand on.Platform is hard to change height and requires a bit of force due to the tight fitting slides.I did not trust the retaining pins, they would slide out with no effort. Would recommend replacing them with real locking pins.Overall seems sturdy enough and the highest setting is higher than I can step without push/pulling myself up and the platform is quite large to stand on. Seems to work well for the price and working on truck engine repairs.
