Sleep Number Bed Smells Bad When New

We love Sleep Number beds - the kind with an air bladder and remotes to get the right level of firmness.  Recently we bought two new ones for the kids.  But the smell of all the off-gassing of the Volatile Organic Compounds (VOCs) was overwhelming for our highly allergic and sensitive family.

We left the mattresses in a spare room with the window open to air out for a few days without success.  They still reaked of plastic.  The smell was in the air bladders and was trapped inside the mattress covers.

I removed the inner bladders and hung them in the garage on some rope to air out.
Over the course of a few weeks the smell of plastic slowly died down.
I put the bladders back in the mattresses and they smelled fine.
We love our new Sleep Number beds now.
