Our Ladders are manufactured with the same materials as the rest of the tree, 3/4” pressed board, 1/4” natural sisal, deep 3/4” metal anchors, and the round steps are 1/4” construction tubing with plastic 3/4” stabilizing discs, We have a few trees that have ladders, in most cases Ladders are only a nice cosmetic feature on a tree, but we have had reports from previous customers stating that their older cat uses the ladder to gain access to a upper condos or levels.
