Could have been much higher rating if more care was given to workmanship quality.  For example, end ballister on top rail was glued in at angle leaving noticable gap on corner of frame. Ladder would not fit in space provided at top end and there was no way to create "wiggle room" to jam it in place (nearly 1/4" too wide). Buttons to fill holes not packed (requested supply be sent). All but a couple of bolts needed touch up paint-not supplied-on heads. Really disappointed because the material itself was sturdy, the assembly instructions clear, and the design pleasing.
