My Engineer husband says this cabinet was very well engineered. 
(ie:Very sturdy)
We read each step several times so we didn't make any mistakes. This took 2 people (70  yrs) about. 6-1/2 hrs over a 2 day period. We shortened the legs by about half to sit under a wall mounted TV.
I am very pleased with this purchase 
I'm using it for linen storage. It works for this. I would have perfered an additional few inches in both depth and width.  
But ventilated linen storage cabinets aren't easy to find
