Anybody work with/repair furniture? I bought a new couch a year ago, and you know they don't make things the way they used to. The foam rubber cushion where I sit (yea, I'm one of those that sits in the same spot all the time, just call me Sheldon Cooper) is all squished and broken down. Can anyone restuff/reinforce it with something that will not squish and break down so easily. The store came out a few months after I purchased it and added more stuffing to it, but it really didn't help. Any suggestions?
