I Need a New Couch

When Hubby and I bought our couch and love seat 10 years ago, we just kind of shrugged when the salesperson pointed out that they both came with a free stain repellent. Whatever. We had two cats, no kids, stain repellent? Yeah, I guess that's a good feature.
These days I'm pretty sure whatever stain repellent was put on the couch is long gone. The first time we spilled something on the couch we marveled at how it just pooled in little beads on the fabric. Clean up was easy. The first few times one of our cats yacked on the couch we were thankful for the stain repellent.
And then came quads.... During the last few years the couch has had numerous bottles and sippy cups full of milk spilled on it, it has been spit up on, peed on and barfed on (yes, there is a difference between spit up and barf).
Fortunately, the cushions have removable covers. Fortunately, said covers are colorfast in the laundry. But when the arm of the couch is involved in the assault, well, there's not much I can do. My current cleaning routine involves Woolite pet stain remover (even for kid-related problems), followed by a healthy dose of Febreeze. After this weekend's "festivities" (ie sickness), my couch smells like a combination of lavender (the Febreeze) and puke. I'm hoping one more cleaning will solve the problem.
For awhile we tried slip covers. Any mess can be removed with the slip cover and thrown in the wash. But the covers just don't stay on the couch. I have a hard enough time being motivated to make five beds each day. The last thing I want to do is "make" my bed and love seat each day, too.
I know I should buy a new couch... but why spend the money to defile a new couch when the old one works just fine!
