Hi Mia12345,
Welcome to the Mattress Forum! :).
Your post was great, well done. You are the princess and pea sleeper…I love that book and the images are so appropriate. But very well explained why you are like that with the spinal curvature, and the additional issues brought on; bursitis and nerve compression. It’s really hard, and so confusing.
Regarding the Amerisleep, the dont list the exact specifications, in another post they were listed for the A2 and A3 as follows:
[i]The Amerisleep AS3 contains(?):
3" memory foam 4 lb
2" polyfoam 1.65 lb
7" base polyfoam 1.8 lb
The Amerisleep AS2 contains(?):
2" memory foam 4 lb
3" polyfoam 1.65 lb
7" base polyfoam 1.8 lb[/i]
Although you have the AS4, If these are accurate, they are good quality densities and there are no weak links in this mattress. I personally don’t like to ever recommend people sending back mattresses. It’s still a lot of const to the companies, your time, gas, freight, etc and many end up in landfills. But really I think you will have a hard time finding your best match. I think you should explore some toppers to put on top of the latex. My first thought is a Talalay 19 ild, 2 or 3" topper. Maybe a 24 ild if this is too soft. This type of topper will give you a little “lift” almost like you are floating, and the pressure relieving benefits of latex are excellent. With your clear medical issues, you are the one that has to really dial in your best comfort. Toppers are not always returnable, but they are awesome on other beds in the house, if you find they don’t work for you. Talk to some of the latex focused members of TMU.

Here is also a post about adding a topper.
And another post about latex and memory foam toppers differences.
Good luck and keep us informed.
Thanks,
