I am thinking (very tentatively) of getting a corner sofa to replace our current two sofas. However, the two sofas we have are both loose covered, and this is important to me as we have a dog and I like to be able to have removable covers for washing. The only two sofas I have found that fit that particular bill are one from dfs, who I don't rate at all (had one crap sofa from them years ago) and the ektorp from ikea, which looks a bit small (currently have a 4 seater and a 2 seater). The alternative would be leather, where there is plenty of choice. Can anyone who has a leather sofa tell me if they are prone to scratching from dog claws? Also, do you find leather comfy or rather cold and slippery? How well does it wear? Thanks.
