It does slightly. I did modify the seat a little myself. I changed the plywood out for a thicker piece and added some padding.
See, I'm 300lbs but have no padding in the rear end. So that's a lot of pressure back there
I didn't change the angle any as I would normally sit up higher. When the need arrives to sit a little lower, I just do that and the seat isn't bad in that position. Modification is very easy.
I have been trying seats/chairs for years and found that most will work in a lot of situations, but few or none work in all. Having the correct seat for the right job means having an arsenal of choices.
If you can't be comfortable, you won't sit still and then you wont' see anything.
