Could be softer for a side sleeper

I'm a side sleeper who suffers from insomnia, but the right bed can cure that. I got an Englander bed 10 years ago that was the perfect bed - I never had a restless night on that bed - ever. And that's the first time I could say that in my life. They stopped making that bed, otherwise I would have bought it again. This bed is similar to that one, but a bit too hard. I'm hoping over time that it softens up, because I don't sleep through the night like I did on the previous one. Also, I sometimes get sore in certain areas on this bed and have to move a lot.
