Microfiber seems to be the trendy thing (at least in our area) right now. It’s fairly easy to clean, although water will stain it, so you have to use microfiber specific (alcohol based) cleaners on it. Most spills will bead up on it, rather than sink in, and you can quickly blot them away with no residue. It has a nap to it, just like animal based suede, so it can look…uh, mottled, I guess? A sweep of the hand can make it lighter or darker, is what I mean, as can your butt. So that, to me, gives it a rich, luxurious look that I like. YMMV.
This is the style I got, although I got it in the sofa sleeper style. Contemporary, but not too much so for me. I like the clean lines of contemporary styles and the rich fabrics and overstuffed comfort of traditional stuff, so this was the perfect compromise for my tastes. The same fabric is available on many shapes, from Contemporary to Country.
Note that it’s also a cheap ass sofa. That’s 'cause I’m poor! But I’ve found the quality to be fine. I’ve had it for two years now, I think, and it’s holding up admirably, despite the earnest efforts of two cats, a toddler and a teenage boy to destroy it. If you have better things to spend your money on, I do recommend Value City - their quality tends to be far higher than their image.
Oh! One other thing to consider - if you’re tall, get a high backed sofa. My husband is 6’4", and the difference between a high back and a low back is a whole lot for him.
