The mattress itself was very firm when we first had it but over the past few days it has started to relax and become softer and is very comfortable.  If you are looking for a supportive mattress to help with back and shoulder pain then I would highly recommend it.  

The delivery itself was also very good.  We were kept up to date with the progress of the delivery throughout and the delivery driver even telephoned me on the morning of the delivery to tell me the expected time of arrival.
