I'd never hit a two year or raise my voice to them unless alerting them to danger all your doing is teaching them it's alright to hit and yell. He isn't doing it to be naughty he's doing it because it's fun and it gets him attention every new thing is exciting when your a kid! He will get bored of it soon enough and move onto something else just be calm and consistent or screw the bed to the wall, equally importantly if he is a climber ensure the chest of draw is fixed to the wall and can't fall on him.Just keep repeating your punishments (although as a side note, I would never use physical punishment to deal with bad behaviour like climbing on furniture). We use a naughty-step for bad behaviour. Option b) make the furniture immovable.
