We are all different weights, shapes and sizes, but have one thing in common when it comes to sleeping which is we spend a third of our lives in bed. There is no one solution that suits all. It is as important to have a good posture while asleep as it is to have one when we are awake so we should choose our beds and sleeping posture carefully.
The normal curves of the spine should be maintained in the neutral position when in bed. The ideal position is lying on one’s side in a foetal position. Place a pillow between the knees to reduce the strain on the hips and spine. A supportive bed (e.g. a pocket sprung bed) maintains the normal body curves supporting your body weight and shape appropriately.
