Very easy to assemble, sturdy for going up or down.  Took a few days to get old charm to get use to it, but once she found out and trust the step that is all needed.  Don't rush your pet, it will come around with little pasince.  I have a 12 yrs old Pug mix and love to sleep with her parents, but the bed got real high as she aged, this Easy Step III pet step solved her problems.  I will deffinitly recomend this product and be used for the intended use.  Also I might add, it set nice with bedroom furnituere.
