Can I add a topper to improve pressure relief on my existing mattress?

Yes, a well-chosen topper such as memory foam, latex, or a high-quality polyfoam can enhance pressure relief on a firmer or older mattress that still offers decent support. However, if the underlying mattress is sagging or unsupportive, a topper is a temporary fix; long-term comfort usually requires a new mattress with both good pressure relief and proper support.
