A lot of the less expensive "leather" sofas at ikea are, in fact, not leather. You have to look at the product specifics for each one to figure out which are which, though.
My friend lusted after one of their bright orange ones forever and was trying to find a vegan version until one day she looked closer and ta da! The one she wanted was vegan.
Oh wow, I had no idea! I just found one each of 2- and 3- seaters that are actually coated fabric! I think I looked once before and the ones I liked were real leather.
