Three different assembly manuals (paper copy, app and online manual)....all told me different ways to assembly the unit.  Screw holes did not line up on the legs and had to be filed to the openings would align for the screw to go in straight. the screws (j) and washer (k) were horrible to secure the legs. Pad secures are NOT "S" hooks, they are plastic clips that break easy.  the bottom support is still not completely attached.  But the kids like it and that is all that matters.
