Why are separate mattresses recommended for double beds?
There are both technical and practical reasons for separate mattresses. First, if there is a significant weight difference between the two individuals, it is important that each person has a mattress appropriate for his or her body weight. In addition, in a single mattress, the movement of one sleeper often affects the resting of the other. This problem is eliminated with the use of separate mattresses. It is also more convenient for each partner to have independent control of head, back and footrest positions. Finally, the bed frame prevents the mattresses from slipping apart, so the center division is unnoticeable.
