Painless under 5 hours.
Hey guys I'm a truck driver and I'm on the road 7 plus hours, this cushion is comfortable but only within the 5 hours after that depending on the person my rear-end will be hurting and its no longer comfortable but more comfortable than driving without it. If that makes any sense. I think because of that slope they added to the cushion now you lose that 2" of comfort but what i do is turn the cushion around and now the slope is facing forward but the problem is now you kinda slide forward which is uhhgg idk the design is dumb. Btw I didn't purchase this because I have pain.<br />I just wanted something other than my actual driver's  seat. I'm telling you though if this was a true 2" all around design I'd be having a cup of stfu and great day.
