Will this seat stay inflated during a long car journey?

BubbleBum inflates to 4" tall with seating area of 12“ by 12’. It fits children 40–110 lbs, ages 4–11. It's a backless booster — it positions the seatbelt correctly. Measure your child’s height to ensure that they’re between 40 and 57 Inches

How do I inflate it — do I need a pump?

No pump needed. Blow into the valve for 20–30 seconds until firm, then twist the cap closed. The cover stretches as it fills — keep inflating if it looks uneven. TIP - keep cap covered by mouth while twisting closed to prevent air escaping.
