My husband and I are desperate to replace our crappy family room couch with something new and are wondering what other people would suggest/have.

We are pretty decided on a slipcovered couch (a la Pottery Barn) for the cleaning ease factor, but wondered what fabric people think is the best choice. How many slipcovers should we get for it (i was thinking either 2 in the same fabric or one for spring/summer and one for fall/winter). I've read in some magazines that people have gotten slipcovers made with indoor/outdoor fabric. How comfortable/soft is this? What about faux suede (microfiber)? Also, are there brands people like? I know PBarn well because I used to work there but not really other places. Crate and Barrel? I know Mitchell Gold sofas are good quality.

Help!
