I take a lot prescription drugs, some that can put You to sleep within an hour of taking it, which was my case! 
I was drinking a bottle of dark chocolate Ensure and fell asleep spilling about half a bottle of Ensure all over my left leg and the new slipcover! A little bit of Ensure did get onto the New Recliner (which we also Scotch-guarded the day before). If I would have had the cover correctly on, then the cover would have caught it all!!! 
The Slipcover is a lifesaver!!! I have since then have washed the Slipcover and is back on Our new Recliner, correctly!!! All look now as new as the day I received it!!!
