I only used this bench for incline and decline, and it was not sturdy. I wasn't a big fan of the tapered seat. It was heavy and awkward to move. it could be stored vertically when not in use. I didn't keep this very long.

It's built like a tank, and it performs like one. From flat bench, incline, and decline you can expect the same level of sturdiness. When not in use it can be stored vertically which helps with saving spacing in smaller areas.
