This is a very simple design that works well with my furniture (black/brown ikea, and dark brown crate and barrel furniture!) it was easy to assemble, no missing parts/holes to drill (see above). i wish the liner was a bit easier to get in/out with the litter box in it. it JUST fits, which is good, but it's a bit of a struggle to get around the hinges. i might try cleaning while keeping the box inside more. it's just tough to empty!
