microfiber
I got an entire new living room set after I got Charlie. The one I had was about 10 years old so it was time anyway. The cute Jackhammer, where they bounce on something till it pops up, Charlie did this to the cushions and ate them when he was mad as a puppy when we went out and left him in the house alone, even if only for an hour, he took on the couch and the love seat and he won! So, when it got to being beyond repair and covering it just wasnt going to cut it, I went off looking. The sales people in every store said get leather, 250 pounds pressure point surely he wouldnt gouge it. Now personally, I dont like sitting on leather, too cold in the winter and if you get hot in the summer.....ew. And the concept of a giant raw hide couch scared me. They then recommended the microfiber, least I'm pretty sure that's what it's called. In any case, takes alcohol and water to clean it off or they say noxema, though I've only used alcohol. It's stood up to Charlie and his power jumping (yes my animals have always been allowed on the furniture heck they nearly own it) and sure enough it cleans up with water and with really tough stains (gf spilled a glass of wine on it and charlie has bled on it after getting fixed) alcohol and water. So, if you have a rambunctious or even just a solidly built dog....this is a very great material to have! Not to mention the cushions are sewn in on two out of three of the set I have. The third is the love seat and I didnt have the patience to wait for it to be ordered and if it was not going to come in miss buying the match so I snagged it and it's a clingy material so the cushions dont flop out even if he were to bounce. And it hasn't marred from him jumpin or waving a paw at it.
So, if you are entertaining a notion of new furniture around your puppy or dog it comes highly recommended.
