I bought a sofa in the school dormitory, but the room manager said that it was easy to be lit by cig

Purchase flame retardant carpet, which needs to be proposed with the supplier, flame retardant carpet must be nylon carpet, professional testing is now required to reach the minimum CFL level, and then a higher level can reach BFL level, but to BFL level less! Generally, it is enough to reach the CFL level for engineering use, but the price of flame retardant carpet is higher than that of carpet with other performance requirements! Lay it directly on the concrete floor or OA floor!

The thickness is not fixed, it depends on the manufacturer's color and weaving, this is not required.

Told my aunt that she didn't smoke and was a good student. You can spread a bamboo mat on the sofa, and now that the weather is cold, if you feel cold, you can put a layer of warmth on the bamboo mat, even if it catches fire, it will not all turn into ashes.

If you don't smoke, you can't remedy it, it's not that you don't let you cook in the dormitory, and there won't be a fire.

What to use an ashtray for, or use a disposable cup for water and cigarette butts.

You and your aunt said you wet the bed every day.

The best thing to do is not to smoke indoors.

Prepare several fire extinguishers.

It's best not to smoke, after all, health is still more important.
