permaeated cushions and other softgoods. The cure
for that: Go to pet store and buy some microbial (MUST be microbial,
not
chemical) pet odor eliminator...remove the covers, saturate the foam
(not dripping wet, but only enough to penetrate all the way into the
middle of the cushion from both sides) with it..put the cushions out in
the sun to dry for day. Send the covers to the cleaners or wash 'em.

Hope this helps you. I found it helpful.
