My Cat Pees on the Couch?

I don't know what to do. My cat, Zeus, doesn't have a urinary infection and is completely healthy. Ever since we got a leather couch from a family friend he has peed on it. It took us a while to get the old couch removed, but during that time I put cayenne pepper and baking soda on the couch. That helped for a while. Then we got another couch and no longer let him sleep on it because he slept and played on the last leather couch, but would still pee on it. So far we've gotten rid of 4 couches in the past 3 years. I've tried spraying him with water after he pees on the couch. I've tried positive reinforcements when he uses his litter box. We have the fourth couch downstairs still cause we haven't had the money to have it removed yet. I put cayenne and baking soda all over it cause it's ruined. But if we drop a piece of mail on the ground without noticing he'll pee on it and we won't notice till an hour later when we smell pee and notice his litter box isn't being used. He has two litter boxes and they are changed every day. We have one cat and two litter boxes and he still pees on furniture, like come on. The oddest thing is when we first get the couch for the first month or so he loves it, cuddles it, and plays on it. Then he ruins it for himself cause he has no where comfy to sleep. I even felt bad one day even though we have no where to sit now in our own living room and got him a cat bed. He used it for a week then peed on it too. The family stays in our rooms now cause we can't even enjoy being downstairs anymore. He'll pee on plastic bags and paper as well. I don't know what to do anymore. He's spoiled with love an attention all the time. I just bought a cage for him today after we yet again found one piece of paper that had fallen of a ledge and been peed on it before I got home. So I'm going to try putting him in the cage for an hour or two now since he just peed on the paper today. Our carpets are ruined. We've cleaned countless times and the smell never seems to fully go away. I'm honestly regretting getting him. I love him, but I cannot deal with this anymore. He was the first kitten in his litter to be litter trained and opened his eyes first. It's been ever since that leather couch we got a couple years ago which is long gone where it all started. From a kitten to age 1 1/2 he was so good with using the litter box. He only used to need one. Now we have two and clean them even twice a day sometimes. I'm lost, please someone help. I'm hoping the cage timeout will make it clear to him that he's been bad. He was in the cage for an hour and I've never heard him meow so much. He isn't very vocal usually unless he really needs to be. So I'm really hoping the timeout made him realize something. Help!
