This situation is not uncommon particularly if the weight of each person differs significantly. Disturbance can be created my one person turning in their sleep or when getting in/out of bed. The mattress type is a major contributor to this situation and the restlessness can be caused by poor posture and peak pressure on hips and shoulders.
Each row of Miracoil springs is made from a continuous coil of wire to distribute weight more effectively. The unique "figure of eight" Miracoil springs gives extra surface coverage and therefore, more support. Each Miracoil mattress gives you and your partner the support you need, despite differences in size and weight. A Miracoil mattress contains twice as many springs as an ordinary mattress. The springs are concentrated in the centre third of the bed to give support where it is needed most. The more weight applied, the more the springs respond providing progressive support.
We also recommend that you choose the largest size bed that your room can accommodate as this will also help reduce partner disturbance as you will both have more space to move around in.
