Perfect, even on hard floors at sea!
I bought this 'mat' specifically to use on the ferry from our island, Isle of Man, to the UK, when accompanying my grandson, Conor, to university. Having driven some 300 miles in the day, to board the ferry to sail back home, this mat was rolled out in the children's play area (as due to Covid, no children were about at 2.15 am and there I lay perfectly comfortable and in an extremely deep sleep, until the vibration of the side props announced our arrival in the port of Douglas, or home, to me. I can genuinely recommend this product, light, easy to use, perfect even on a hard floor, what more could you ask of it.
