Axiom G vs JAY Go cushion

I'm getting my first custom chair in a few weeks, and I've been looking at cheaper options for cushions until I'm able to afford a ROHO. Wondering if anyone has any experience with the Axiom G and/or JAY Go cushions, I'm leaning more towards the Axiom because it's a good bit cheaper, but I'm not sure how firm either of them really are. I'm at moderate risk for pressure sores and while I know basic use cushions aren't gonna be perfect, I'm self funding my chair and I can't really spend 400$ on a ROHO atm lol, so also open to any suggestions for halfway-decent cushions in the 100-250 range
