Do you need an additional back support for road trip travel with this? Another piece to go against the seat?

I found that this was good enough, especially if you keep a little space between the backrest of chair and cushion. It kind of nestles you in. Also, if you use this AND a back support, there might be too many items on the seat, thus affecting your actual seating room. If you have back problems, Id just go with a back support and no seat cushion. 2cents.

Is this suitable for larger people or does it flatten out?

I am 190 lbs, weight has been fairly constant. My career choice finds me sitting in a chair in front of computer screens for very long days (40-60 hours per week) year round. I purchased this cushion in March of 2019. It is now January 2022. Thinking I might get a new cushion. The front of the cushion is now flattened to 1 1/2 inches from seam to seam in center of each thigh segment. The back is still at 2" and does provide some support (measured when I got up from seat after sitting continuously for an hour). Overall, I feel the support is weakening and this cushion should be replaced. It's been just short of three years, which is beyond satisfactory for the cost and benefits provided.

Do you have any certificates for this cushion?

I did not receive any certificates

Can you tell me the dimensions of this; I'm looking for a cushion that will fit the bucket seat of my Chevy Cruz, so nothing more than 12" to 13" wide

Sure. I measured about 17 1/2 wide, 14 long. Looks like it would be too wide :(
