I have an aging dog that loves to sleep on our bed, but it's too tall for him to jump up on anymore.  These steps are perfect. First, they come right out of the box with little assembly. All I had to do was put the stair treads on the steps.  It fits right up to the bottom of my bed and he can easily walk right up.  I only wish these came in different colors.  Not a fan of the plastic looking gray. But that's just my opinion.
