   You aren't going to "wash" a chair.  For a chair, just use Tyvek or a plastic   
   sheet, to minimize air exchange.   
      
   If you hadn't said "asthma", I would have suggested an ozone generator, say 1   
   gm/hr.  Ozone directly attacks aromatics (heat, humidity, and visible light   
   helps), but it also "blinds" the nose (and triggers asthmatics).  More than   
   likely, you will have to    
   compress and decompress the chair's cushions a few times, to exchange ozone   
   into the material / foam.  Hot vinegar fumes might do as well, and do less   
   damage.   
      
   I have seen phenomenal results bagging items, pulling all the vacuum a shop   
   vac can pull, let fresh air into the bag, and repeat as necessary.  The "fresh   
   air" could have different compounds added, since they will be pulled down into   
   the materials that    
   are at lower pressures.   
      
   Good luck.
