As someone who used to make such things, I second the advice given: mock it up with whatever you can, to see if it would be effective.
To be a good mock up, you need to know what hinges, and where the hinge points are.
From memory, there is usually only a short central section that is static.
Talk to the supplier/manufacturer for measurements of the sections.
A long "head" section that raises the upper body, and a lower section with an intermediate hinge that raises the legs, hinging around the knee point as it comes up.
Maybe find a second hand one from ebay/Facebook marketplace, etc.
If you do manage to mock it up, give it time. What gives relief for ten minutes may be uncomfortable in an hour or three.
