Easy to assemble and my cats like it! I didn’t think about this before, but it’s a little strange that the lowest level is the hammock, so it’s a larger jump for them to get to the first solid level. My cats are fine with it, but might be a consideration for an older kitty or one who has trouble leaping. The material is super soft, so I hope it holds up under long-term claw usage, but we’ve liked it for the first couple of weeks at least!
