Medium tension mattresses are regarded as the goldilocks of tensions. This is due to their one-size-fits-all approach to comfort which will generally see most people who are underweight through to overweight still being able to find a degree of comfort with such a purchase. Medium tension is great for back sleepers, side sleepers and front sleepers with the only real caveat being that those with backpain or a larger BMI than average may want to consider a slightly firmer product.
