Some will say that they incorrect, others that these are pleonasms, but people keep on using them. Are they actually using them as gradable adjectives or are the superlative forms there for emphasis? You'll hear 'most perfect', but what about 'reasonably perfect'? The usage tends to reinforce the adjective and not to slide it up and down a scale. I suopose the question of whether it's OK depends on your audience; it will probably irritate the pedants and grammar police.
I'd use 'more/further to the left/right'.
