Once you have found the right angle, you can release the lever or knob to lock the backrest in place. This feature allows users to customize their seating experience for comfort and support while working. **

Airlines design their classes to cater to different passenger preferences and budgets, so a class with reclining seats but without luxury may not align with their target market or branding strategy. **
