บท 66: Mattresses
A 10-year old mattress weighs twice as much as it did when it was new. A mattress has between 100,000 and 10 Million Dust Mites in it. The extra weight comes from dead skin cells, dirt, dust, mold, perspiration, and lots of dust mite carcasses and droppings.
Water beds aren't a new invention. They used to be made of goat skin over 5000 years ago.
By US federal law, mattresses need to be able to withstand flames for 30 seconds.
If you live in Washington, you won't be able to buy a mattress on Sunday as it is illegal.
Most people don't seem to realize that mattresses can be recycled. As a single mattress already takes up a substantial area, therefore recycling would have a greater impact.
