I am wondering what makes up the vertical (white) supports. I had assumed they were metal but a closer looks makes them likely some kind of wood product, but not the “bamboo” of the shelving. Unfortunately an Amazon negative review says they are particle/composite board, but a lot of Amazon reviews aren’t factually correct, so I’m not sure.
I bought the smaller SONGMICs shelf called a “plant stand” and it had vertical supports of bamboo which was nice. I’m concerned that the white vertical supports for this shelf might be inferior and disintegrate over time as many composite wood products do (if Amazon reviewer is correct in description). Metal would have been OK but now I don’t think they are metal either so not sure what I would be getting.
