Questions?

What is the diameter of the cup holder? I want to ensure my child’s water bottles will fit.

It is approximately 3.5″

How wide is the seat between the arm rests? My child has wide hips and I want to make sure he fits.

14” near the back and it opens to 15” near where the hands rest. My 5yo wears a boys size 10 or Medium and he’s comfortable in the seat.

Does this seat have a reclining feature?

The seat does recline one position to adjust to a vehicle seat back, but you want your child sitting as upright as possible when they are forward-facing, much like adults do when we ride in the car.
