My aches and pains have disappeared!
Our old mattress was well and truly old and needed replacement; we had a very firm mattress for my husband who has a bad back however it was not suitable for me as was waking with excruciating pain in my shoulder. The option for half and half was ideal. The first night I did not wake with excruciating pain but still had pain in my shoulder. This pain subsided over the following week and don't have any real issues anymore. I was happy with the medium, however felt liked softer, and moved to the soft mattress which I do have preference for.
