Box arrived in poor condition, fortunately it was packed with styrofoam on all sides. Which saved the end pieces but just barely. Good Quality  sturdy for boxed furniture. 
The primary hardware screws was hex head with small hex wrenches, caused slow assembly  difficult to get tight enough. Would have been better with Phillips head screws. If using for litter box you need a single height one or the exit opening with scratch pad cannot be accessed by the cat. I’m using the space to store the box of cat litter.
