Narrow Booster Recommendation

Cosco Topside Booster Car Seat
Howdy all. Just wanted to recommend a narrow booster that fits the Tesla X perfectly. It does not cover the seat belt buckle insert so your child does not have to struggle. Both of my Graco (Affix and Backless) boosters covered up the buckle completely and it was very difficult for a child to buckle without unnecessary struggle. I love how the seat belt buckle stays down in the seat for aesthetics but it is a PAIN if you don't have a narrow booster. This Cosco (note NOT Costco) one is perfect. See how it fits in the X 2nd row in the 2nd picture. I got mine on Amazon for $11. Can't beat it!
