Mine is a brown leather sofa and two chairs.
The chairs rock, swivel and recline and the dgc love them. They are big enough that two can sit (closely) side by side to watch tv.
15 years old and fabulous. Has been through a cat who hated it, and 6 dgc who each have jumped, slept and rolled on it throughout their toddlerhood. Plenty of sticky finger marks that wiped off. It gets a leather wipe about every month. The only mark is where the buckle of a wee shoe scratched it. No bother with hot or cold and the cushions stay in place without issue.
I sometimes feel I'd like to change one of the chairs as they are big but know the dgc would miss it so much.
I'd buy leather again in a heartbeat.
DS has just bought his third leather sofa (he has a big house) so he clearly has no problems with leather...and he has two children and 3 dogs.
Years ago, When our brown leather furniture arrived it would come in neither front or back door. DS and DH and friend took the double glazing unit out of the living room window to get it in.
This was at 7pm and it was getting dark, there was me having a dancing hissy fit and pulling my hair out thinking they were mad and saying No No No Way !! Furniture was in and the glass unit back in place within a half hour.
In my innocence, when they said take the window out, I thought they meant the white plastic frame included. It was bad enough when I saw the glass unit out.
