Convert your OP4 rear double bed into a king with the king bed cushion upgrade, and make the most of your space! Additional leatherette custom cushions enable you to easily switch out the lounge seating with a bed extension, increasing your bed size from the double (1260 x 1830mm) to a north-south facing king (2180 x 1830mm). One of our most popular upgrades for the OP4.
