Hubby made a cover for the stairs that is flush with the floor so our 1 year old won't fall down it. He made the cover foldable with a fence hinge and will be mounting it behind the handrail when not in use. He used 2 squares of FLOR tiles we had extra of and cut to fit. It's pretty solid and my dog loves laying on it and my kid can't fall down it
win/win!
