For the last ten years it's been a latte brown/grey, okay greige, 3 seater. I'm loathed to get rid of it as it still is so comfy, though somewhat worn and faded. Desperately trying to the find a drill, cotton or linen in a bright teal/ kingfisher/ peacock blue to re-cover. Something like this...

The most kid and pet friendly couch material is leather. So far our blue leather couch has coped with 18 years of toddlers falling asleep and weeing on it, cat vomit, Easter eggs melting between the cushions, spilt milk, spilt orange juice, spilt red wine, spilt coffee, and muddy dog paws. It just wipes clean. Our white leather chair is just as durable and is now 24 years old and just starting to look grubby. So go with beige or cream if you want. It would be a lovely choice, just make sure it is leather. Black or mid or dark brown would also look lovely with that beautiful rug but I think lighter colours would look fresher. Don't be at all scared to use light coloured leather.

Mate, start bidding, I would if I had the space! http://www.ebay.com.au/itm/VINTAGE-RARE-SMITH-AND-CO-CHESTERFIELD-TAN-CIGAR-2-SEAT-SOFA-LOUNGE-COUCH-SUITE/282194290880?_trksid=p2141725.c100338.m3726&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20150313114020%26meid%3D9ae17f7c19224fd7b11591d4fb71dce7%26pid%3D100338%26rk%3D10%26rkt%3D22%26sd%3D262634019312

Hi Katrina, Overall the sofa looks just too big, even though essentially it fits on paper. It would be better to go with a 2800 L shaped sofa with chaise and have the chaise side running by the wall so it's a bit more open as you walk in. And if you make the chaise 1600/1700 then you have more room to pull the sofa a bit closer to the TV and make space for your dining table behind. Or pop the chaise on the side closer to the kitchen then you may have room for an occasional chair on other side by the window. Does this make sense?
