I bought this for a cat tree a year who loves perching in height. The product arrived very quickly. Mounting rather easy if you are used to pack furniture and their inimitable notices. The tree is set well (2,50m ceiling home). However, it should regularly tighten the pole that allows to calibrate the whole ceiling to ensure that nothing moves. The tree is stable and looks solid. The cat loves climbing along the posts of sisal, jump from one platform to another, from one platform to a hammock ... a little boisterous play that shake the tree but do not call affect its stability. Since the tree is up, my cat sleeps every night in one of the hammocks. Just installed, already passed! A good buy at a fair price when compared with other merchants.
