We have a huge sectional sofa that dominates most of the living room. It's ugly as sin, but it comfortably fits all family members. It's a taupe-colored microfiber monstrosity. My husband picked it out when we moved here, despite my protests that microfiber is about the worst material you can have if you allow dogs on the furniture. He refused to believe me, so eventually I got tired of arguing and let him buy the damn thing. (For the record, I wanted leather.)
We need to keep it covered, but there isn't a slipcover in existence that'll fit it. We've tried just about everything - quilts, blankets, sheets, etc.
This evening - after more than four years of ugly-sofa ownership, I figured our the idea way to protect the cushions. SLEEPING BAGS. I simply shoved the cushions into sleeping bags, zipped them up, done.
I can't believe it took me this long to figure out.
