SleepSoul Comfort 800 Mattress

For a side sleeper, medium tension is the right amount you need in your mattress. The springs are less rigid than those found in firmer mattresses and therefore they offer the cushioning your shoulders and hips need, allowing your spine to rest in a healthy and natural alignment. A firmer mattress would put resistance against your shoulders and hips, not allowing your spine to align, resulting in you waking up with aches and pains.
