This ended up working out great for my needs. For someone like me who moves a lot and needs to be able to fit whatever in my car this does the trick. It’s not fully plastic and unstable although no earthquakes yet.
Basically metal frame and adequate support for the drawers, can disassemble as needed easily and reconstruct.
As with everything always room for improvement. I would suggest to the vendor some way of adding a stop for the drawers as they pull out as well as an easier glide.
