15 mths is definitly not too young for time out! if you start now, it makes it easier when they're older. instead of trying a time out in a chair try something alittle bigger like a mat (i bought the cheap $2 rugs from walmart). that gives them alittle more wiggle room at that age. just don't expect him to sit perfectly still. the first few times will be hard. as long as you're consistent it will work out. my son is 4 now and i do a slightly different time out system (he's always getting in trouble for his temper). i put him in a bean bag chair in his room and tell him to come out when he's calmed down. sometimes he's only gone for a few seconds but sometimes he's in there for alot longer. when he comes out i tell him that isn't okay, get an apology (as sincere as i can get it) and then it's over.
