I can’t say enough good things about these CozyUp pet steps! I was looking to replace my old pet steps as they weren’t tall enough to reach the top of our bed. I was pleasantly surprised by the quality of these CozyUp ones. They’re constructed of heavy duty plastic that seems very durable and I like the non skid feet on the bottom to keep them from slipping around. My favorite part though is the fact that you can fold them down to stow away when company is coming.
