This was simple and quick to put together! It's a perfect size - just the right height - and the top section is so nice and roomy! Plenty of room for my kitty's bowl of crunchies and for him to sit comfortably up there and eat. Just high enough that my Yorkie can't reach the kitty food but easy for my kitty to get up there! We love it! I can't believe how perfect it is for what I needed!
