## Questions & Answers

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

**Q: Is this suitable for larger people or does it flatten out?**
A: 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.

**Q: Do you have any certificates for this cushion?**
A: I did not receive any certificates

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