if you are truly worried about fumes, never buy a house under 12mths old, the formaldehyde that escapes from the bench tops is bad for you, don’t drive your car in summer, the BSPA from the plastic will be attacking your nervous system!
OOO Fly spray is a neuro toxin, don’t go to the public pool either, there is chlorine gas, trichlor-iso-syurnaric acid, dichloro-syuranric acid and bicarb soda used there, yum, swimming in brine.
just saying

if a room was to combust the average burning temp with all the synthetics is well above 1400 centigrade, the tyres will be the least of your worries, you might even be able to use them as a temporary shield to get out of the fire

This is a very creative project. Hopefully there won’t be any fires as that would be tragic to anyone but in the event there is, no smoke is friendly anyway and all cause problems.
Safety first so fires are avoided. I love these chairs and will try making some 🙂
Lighten up a little…be creative and enjoy the results 🙂

Most any cube type seats like that are filled with a polystyrene filling anyway. Very noxious stuff. You might want to only consider only all solid metal furniture. Even wood burns.

your worth less

How will it catch on fire? I am thinking on making one of these for my son’s room. To me, it dose not seem to be any more dangerous than a store bought item. Carelessness is the only way I can think that would be an issue. There are many things in the house that if caught on fire would be toxic. Please let me know what your feeling is about this chair. Thanks, Ron in KS.

Bravooo!

It says the back is made from wood palettes
