In my lifetime I’ve sat on a few outside sofas of questionable provenance but never one I felt required haz-mat suits to safely lounge on.
(Couch halo due to slapdash Photoshop enhancement, not beatification.)
UPDATE: OMG!!! On the advice of The Boyfriend, I finally went to Clean Scene Services’ website and, um, now I know why that sofa probably is a biohazard. Yeesh!
