They are lovely solid teak chairs not the plastic beloved by other lines. Choose the position of your cabin carefully always. Not all suites/ balcony cabins are affected.

we have just returned from our cruise and had a suite the chairs are not fixed,they do not recline they are made of wood and heavy to stop them moving in the wind i think. i would advise you to think about going one deck down (deck 10) because we were woken each morning at 6.30 to the sound of people moving sunbeds on the wooden deck above.or take ear plugs friends who had an inside cabin on deck 5 slept in untill 10 30 each day and spent 1200 pound less than us
