Too hard for side sleepers with back issues

We ordered the Leesa after tons of research and review reading on mattresses, we really thought we had found the right mattress. When it arrived, we were a little concerned over the initial firmness of the mattress, however, it does give some after a few seconds of laying on it. After about a week of some soreness common after changing mattresses, we did acclimate some, and felt some relief over our old pillow top. I am a side sleeper with some pretty severe back issues, and although a slight improvement over our old mattress, after about 8 weeks of still waking with a lot of hip pain and numbness, as well as neck and shoulder pain and stiffness, we decided it was not enough improvement to justify keeping it; and wasn't going to work for us no matter how much we had wanted it to. While my husband did not have as severe issues with the mattress as I did, he honestly just found that it was too firm to be comfortable, and also found it to be too hot. We initiated the return, which I wouldn't exactly call easy, but it could have been much worse. The charity should be picking up tomorrow, if all goes as planned. Although we found this way too firm, and not very supportive, I know mattresses and sleeping preferences are very personal, and I honestly can see how the Leesa would work for many people, particularly those that would like a firmer medium-firm mattress (like a 7-8 firmness scale). But, if you are a side sleeper, and have any back issues similar to me, or need pressure point relief, this may not be the mattress for you. After some further research, knowing what was not working with this mattress, we ordered a Layla, which arrived today, and although we haven't slept on it yet, I am very impressed with it after laying on it for a few minutes after setting up. I really hope this is the one, we could really use a good night's sleep with hopefully some pain relief as well. :) We will come back and review after giving it some time. Fingers crossed.
