seemed strong, but broke within a year
i loved this, very good value and large enough for cats to have a good stretch. went to tighten it the other day as it was wobbly, and found out its not the screw that neds tightening, the bottom of the trunk has come away, so nothing can be done to fix the wobble. dissapointing really, as initially impressed. would have hoped it would have lasted a year at least.
