The Amazon Basics Cat Activity Tree is an indoor cat tree that provides plenty of scratching posts and surfaces to keep your cat entertained. The tree is made of sturdy medium-density fiberboard and is covered with carpet that is easy on the cat’s paws. The round top platform with raised sides and curved rim doubles as a cat bed, while the stable square-shaped base is ideal for placement in room corners. The simple screw-together assembly is easy to assemble and comes with instructions and tools.
