There are a few different types of mattresses that can help with lower back and hip pain. A firmer mattress is often better for this type of pain, as it provides more support to the spine. However, some people find that a softer mattress helps to reduce their pain. There are also speciality mattresses available that are designed to provide extra support to the lower back and hips. These can be helpful for people who have chronic pain in these areas. If you're not sure which type of mattress is best for you, it's worth talking to your doctor or physiotherapist for advice.
