I rode the trike 15 miles today. Climbed a fairly stiff 2-mile hill between the 7-1/2 to 9-1/2 mile markers. No issues with the mesh seat. very comfortable. Before I started, I did place a 1-1/2" wide x 3/4" thick block between the seat connector and the main tube. What this did was push the lower end of the seat slightly up in the air so that I wasn't fighting sliding down off it. Good ride with no seat issues.
