Best wood for KSB rack

[eleni]

So, I want to build a rack that would hold 4 adult KSB, 1 adult BP, and 20 slots for baby KSB. I plan on putting the BP in the top slot and using pvc for the top shelf since the humidity for her would be a bit higher and may damage wood. For the rest of it, however, what type of wood would you suggest and what thickness would you suggest? Thanks

Have you considered melamine?

[eleni]

Yeah, but I've heard that it's really heavy, would you suggest that maybe I reconsider it?

I like the idea of it... It's supposed to be easy to clean, holds moisture without warping...
