Editorial
Sources we read
Every quotation on this site comes from a document we opened and read on the date given. Nothing is quoted from memory.
We quote federal agencies where a piece of furniture touches safety or health: the rule about bunk beds, the smolder standard for upholstered furniture, the wind scale we design outdoor pieces against, and what the Forest Service says about the cedar we use. We do not quote to decorate a page. Each passage below is checked character for character against the saved text of its source every time the site is built.

What this site does not do
This is not medical or safety advice. A bunk bed rule is quoted so you can read what it covers, not as a substitute for reading it yourself. Where we say a piece meets a standard, we say so because the piece names it, where it does not, we say nothing.
