Yes, a mattress topper can help reduce hip pain and prevent new pain from occurring. This is especially true if your mattress feels too firm, or if it has developed indentations and impressions over time that cause the surface to feel uneven. A softer mattress topper measuring at least 2 inches thick can significantly improve how comfortable your mattress feels – but this should be considered a temporary measure, not a permanent solution. Eventually, you’ll need to replace your mattress.
