Not quite right

I researched this mattress and had high hopes but found it to too firm for my liking. I would say that the issue for me is that the middle layer needs to be a bit more soft. The top is soft enough but I was bottoming out and I'm not huge, my BMI is 27. It felt great sleeping on my back but I prefer to sleep on my side. Sleeping on my side made my arm go numb. I would force myself to fall asleep on my back, then wake up on my side and toss and turn the rest of the night. They sent me their topper and we tried that but it was a low density, soft foam and didn't help. I appreciated their willingness to try to make it work. But in the end it wasn't working. I did appreciate that the mattress didn't sleep hot and appeared to be well made. I liked that it was made in Arizona. I "returned" it by donating it to a charity as per their guidelines and mailed back the topper. I think this mattress would be excellent for a back sleeper or side sleeper. My review of the mattress is mostly based on my comfort. It does seem to be a good mattress if you prefer this type.
