New mattress regulations that require manufacturers to meet a stringent open flame test take effect Sunday.
At Sealy, which is based in Trinity, North Carolina, company officials say they're ready.
For the past two-and-a-half years, Sealy has burned mattresses in its flame resistant test center.
The million-dollar lab allows the company to test new ideas right at corporate headquarters.
The Consumer Product Safety Commission says the new open-flame regulation is the most expensive set of rules it's handed to any industry.
It will cost at least 100 (m) million dollars a year for manufacturers to comply each year.
At Sealy, officials say the change has also meant using more science and engineering knowledge to produce mattresses.
