What’s wrong with stairs?

A new report by the National Review concludes that “a simple switch of the wrong door, a door that needs to be turned in the wrong direction, a faulty installation, or an inadequate elevator shaft could render the stairs useless.”

The authors point out that stairways are “essential infrastructure for all American families” and “are essential for those of us who travel frequently.”

The stairs in question are in many ways the most basic element of modern life.

But despite the common misconception that stairs are inherently dangerous, the researchers say they can be safely installed and maintained.

In fact, according to the authors, “the stair is one of the most important and least expensive components of a house.”

The researchers found that in most cases, the installation of stairs is straightforward.

“In most cases where there are stairs, there is no need for any additional maintenance.

There are, of course, exceptions, but in general, stairs are relatively inexpensive.”

So, if you’ve never installed a staircase before, here’s what you need to know about installing stairs.
