The instructions do suck as few reviewers noted. A simple way to remedy this is to take a very good look at the photo of it on the web, take a good look at the bill of material, realize that there are 3 different lengths of various posts and two flat platforms are slightly different - one has a pre-drilled hole for a rope, the other doesn't. Then start building it from bottom up, NOT from the top to bottom as the instructions suggest. Make sure you tighten each section well before you attach a next one. As few reviewers suggested, skip the ladders, totally useless, our 3 months old kittens have no problem jumping from the floor straight up to the top of the lower hiding hole, no ladders needed anywhere. Also, the very top piece (and a long screw with a wingnut on it) seemed to be a bit of a mystery until I realized that it serves as an expansion piece so the whole construction can be tightened up against the ceiling (8 feet ceiling) which severely improves overall stability of it. I also switched a few pieces around (middle platform with a basket) to what I thought the cats will like better, it's quite doable. I'd give it 5 if it wasn't for horrible assembly instructions. BTW, if you're dead set to not buy "Made in China" stuff, this IS made in China, I was disappointed but not surprised. It took about 1/2 hour to assemble, fits nicely in the corner of their room. The rope isn't sisal but looks like manilla rope. The cats (three 3-months siblings, one 5-moths old) like it and use it for scratcher posts. Would I buy again? Probably not but only because it's made in China. I'd build something similar myself instead (I am relatively comfortable with hand tools).
