Everyone loves hardwood floors and stairs for their beautiful finish, but the truth is that their slick surface ensures at least a few slips and falls. For homes with small children, dogs, or anyone who's prone to life's clumsy moments, stair treads provide a safe solution to that problem. Not only do the treads make staircases safer, but they cut down on dirt that might otherwise be tracked upstairs. The treads adhere easily with the help of double-sided tape, and can be removed for cleaning and then reattached when necessary. Available at Amazon; $89.99 for a set of 13.
