Is there a top tether on this seat?

No, it does not. It is secured to the vehicle seat's fastening system. The seat belt in the vehicle does the job of keeping the child safe.

Because of my daughter's wide hips, the gap between the armrests in our present car seat is an issue for me. Anyone know how big it is?

Answer: Because this is an XL booster seat, it should be sufficient, and the space between the armrests is around 16 inches.

Is this car seat foldable for traveling?

The Cambria 2 does not fold, but it may be converted to a backless booster because the back and bottom are distinct pieces.

Could you please tell me when I should start utilizing this? What size does it take? Do you think it's worth buying?

Answer: Because the minimal user weight is 40 lb / 18 kg, we encourage utilizing the seat as soon as your child reaches that weight.

Would this suit my three-year-old? He weighs around 40 pounds.

The answer is no. A 40-pound 3-year-old should be rear-facing in a convertible 5-point harness (even if their feet contact the seat), since it is 5 times safer. I'd look at the Diono Radian. Boosters begin around 6 for average-sized children and possibly 5 for really large children. If rear facing is not practicable, he should be forward facing in a 5 point harness.

Is there a tether for this seat to attach to the car?

Yes, it has the Latch System. Do you notice the two straps protruding from the front? Those are used to tighten the straps (tethers). There are two hooks on the bottom that can be attached to something. I didn't have the Latch System in my truck, but I was able to secure the hooks to the frame. They claim they are not necessary, but they keep the seat in place.

Does this fit in the Tesla Model Y?

This car seat will not fit in a Tesla Y 2021. The base is extremely large, making it impossible to connect the seatbelt.

Is a top harness strap required for this?

The answer is no. This is a booster seat with no harness option. Description: Diono Cambria vs Monterey XT
