This is the perfect mattress for me. It is very firm so it provides support to my joints and bones while I sleep. I previously had a high quality memory foam mattress which didn't provide enough support so I woke everyday with a sore back and hips. Those issues disappeared the first night I slept on this mattress. The support is all the way around from the sleeping area to the sides and edges. I highly recommend this mattress for someone needing firm support.
