The cats love it. The instructions were easy enough, but basically just a picture to follow along with. It is worth noting that the "cave" section is small on the inside as it's supported by two columns that look like paint rollers. The cave is like a pillowcase that slips over top of a hard oval on top and and a hard platform oval on bottom. For us, our male cat is a bit big (13 lbs) for the hammock section, but small cat likes it. Overall satisfied with the quality for the price.
