I ordered the full set, but only ram came in. Contacted seller, and instantly solve the issue. Awesome customer service. The whole thing seems well built. The wood pieces are all polished to reduce injuries. (Except the locking stars) The set came with an instruction or design paper for you to see what style can be built. Not step by step, unfortunately. Not an issue for me tho. Each joint is using a locking piece snap into place with 2 stars shape of wood to lock into places, and each joint will require one lock. Therefore 2 locks for each joint, and the pressure of the locks is split onto 4 stars. This, helps to spread the force and reduce chance of breaking. Very good idea, well thought. Yes, that will require a lot of extra work to lock each pieces, but hey, it is to make sure your kids are safe! They say the structure can support more than 100lbs on it..... I don't wanna risk to break mine therefore we didn't try..... Anyone that has very deep pocket can try . It does come with one minor drawback . Since there is no marking or such on each locking, therefore it will take time and patience to design and make a structure completely right and stable.
