Open windows if you can.
Also though they are hard to come by these days and sometimes smell like the perfume ad inserts, if you can get some untainted newspapers to lay over the furniture it will act like charcoal of sorts and help absorb some of that.
You will also need to change out the papers often though as they get saturated with the odors.
If you cannot get those, I found a cotton thermal blanket very helpful with a foam wedge I bought for my Mom last year.
It also did a good job of absorbing the odors but again, it has to be washed once it gets saturated with the smell and I still did need to open the windows when I could.
I agree with Ben, too. Move it outside, if you can, or at least to a room where you can close the door.
Unfortunately, it still took a couple of weeks before I could put it under her mattress and even then I covered it with a sheet.
