Well perhaps that is stretching it a bit but here's my story:
The seat cushioning on my Mahindra is very similar to that found on many CUT's. A hinge on the front with two compression springs near the back of the seat bottom....
I noticed the "ride" as being very stiff so did some calculations on the spring rate with the being made of 6mm wire wrapped with about 5.5 active coils and 1.5" spring inside diameter.
My results show a spring rate of 165 lbs/inch of compression times two springs. ( At least 330 lbs to deflect the seat down 1" and that doesn't even take into consideration that the hinge is absorbing 1/2 of the load) The problem is that I only weigh about 190 lbs so it's about riding in a lumber wagon going down a less than smooth road.
I do agree that "air suspension" in the thread title may be stretching (or perhaps compressing) things a bit, but doggone it, the 2.80 x 2.50-4 inner tube is rather cushy.
Now I'm not planning on adding a 12VDC compressor or anything silly like that, but adaptive ride control would not be totally out of the question.
