During my testing, I was impressed to find that a firmer mattress really did lead to big improvements in my back pain. I expected a harder surface to cause flare-ups of pain or to even throw my back out of place, which has happened on cheap, hard mattresses before. However, I slept well and woke up without any aches or soreness. While a softer sleep surface was my go-to since I’m a side sleeper, choosing a firmer style of mattress immediately supported my spine better and kept pain away, rather than flaring it up like I assumed.
