The last mattress we slept on was approximately 30 years old! The first night I slept on the new mattress I tossed and turned all night long! The next day I was so tired I wondered what in the world to do with a mattress I couldn't sleep on??? My husband who never sleeps well said he had the best nights sleep he had in a long time. I didn't tell him I didn't sleep all night and decided I would keep trying to sleep on this thing. The next night I slept much better and now I really like the mattress. My message to everyone is give a new mattress some time and your body will adjust to it. I am now getting the best sleep I have had in years and no longer think I would give it up!
