I am going to try single fitted sheets first, but if they don't work, I'll be doing this. Even though my porch is covered, I need something to keep the pollen off the cushions when they are not in use!
Fingerhut custom-fit plastic furniture covers - In the 50's and 60's you protected your upholstery at all costs! These plastic covers were interesting in Summer. Short-shorts, sweat, bare legs and plastic?!?! I remember pealing myself from a neighbor's sofa one July in Georgia.
