The description is misleading as the hammock is made of MDF and NOT solid wood.  That might have been fine if the arms screwed into the studs for extra support, but that isn't how it works.  The arms are attached to the MDF board with short bolts, so when the cat sits in it or walks across it the arms wobble and bend inwards. One of the sides where the arm is attached snapped after my cat used it three times, MDF just couldn't take the stress.  We're trying to decide on if we like the rest enough to keep the set even with a broken hammock or just return it.
