You can’t afford 3k seats! You obviously don’t belong on this forum… Where ballers unite.
On the serious tip though, a good seat keeps your back/etc in check and in position so it should be comfortable for long rides even without reclining.
Only aftermarket seats I’ve purchased are fixed back, so I’m sorry can’t give any suggestions based on actual experience.
What car is this going into? Any improved OEM options for that car in terms of seating? Could cost less, and it will be a reclining version…
