SleepSoul Heaven 1000 Mattress

Medium tension is ideal for side sleepers since the springs aren't as rigid as those found in firmer mattresses and therefore give way to the shoulders and hips, allowing your spine to achieve a natural and healthy alignment. If you are a front or back sleeper, it would be more beneficial for you to have a firmer mattress, since it offers better support for these sleeping positions than a medium mattress does.
