A chair in mid-impact

It's not just you, it's science. A chair's lifespan is measured in months, not years. And when it's gone, it's gone for good.

Code to detect the impending impact:
		`if (legs[0] != legs[1] || legs[0] != legs[2] || legs[0] != legs[3]) {
		alert("CRASH IMPENDING!");
		}
	

Seriously though, inspect for any damage before the inevitable crash occurs.
