Double or king?
A double gives each of two sleepers 67.5cm of width. If either of you is restless, over 6ft or wakes when the other moves, the extra 15cm width and 10cm length of a king is worth it, if your room allows. In a double, pocket springs make the biggest difference to partner disturbance; see mattresses for couples.
