Question about wooden ledges for cage

My 8 year old chin loves doing parkour off the walls of his cage. I recently came across a wooden ledge in the pet store in the bird section and bought it for my chin to try out. However, it did not specify what type of wood it was. It is by a & e cage company and says it's great for chinchillas, but as you all know, this may not always be true. I have attached a link to the ledge here: http://www.aecageco.com/Products/New-Products/NB007-Corner-Shelf-Small.html
Thanks, all
