Do I need a softer mattress?
If you're of a lighter stature or you prefer to sleep on your side, you may find that a softer mattress is better designed for you. Such mattresses can provide optimal support as the low tension springs won't be strained under a lighter person, and extra cushioning around hips and shoulders ensure proper spinal alignment for side sleepers. If you're heavier, you can expect to wake up with aches and pains after sleeping on a softer mattress, as the right level of support is not there for you.
