Awesome, sturdy and preassembled! I  purchased this for one of my cats. I have a dog that will eat cat food  so I have to keep it out of her reach. Unfortunately, one of my cats is not a very good jumper and needed a pair of steps to be able to walk up to his meals. I was a little worried that he might not use them but I made a little trail of cat treats and he followed  it right to the big payoff. The steps are worth every penny! The quality is fantastic. I was surprised by how heavy it is. I definitely recommend this  product!
