The Cosco Kids Finale DX 2-in-1 Booster Car Seat is a forward-facing only seat that converts from a harness booster (40-65 lbs, 43.4-49 in) to a belt-positioning booster (40-100 lbs, up to 52 in). It is designed for lightweight portability (approximately 11 lbs) and a narrow profile to fit three across in vehicles like the Tesla Model 3, making it popular for travel, carpools, and secondary use. Key features include a removable machine-washable seat pad, dishwasher-safe cup holder, and five-point harness; however, the thin padding may be less comfortable on long trips.

Clearance find and three-across fit in a Tesla
I got the Cosco Finale at Walmart for $30 on clearance! It fits three across in the back of my Tesla Model 3 with two other car seats. It's super lightweight and easy to install.

Installation ease and comfort concerns
I love how easy it is to install and it's so light for travel. But my 4yo complains it's not cushy enough for long rides. The crotch buckle is a bit tricky to tighten.

Tesla Model 3 three-across success
We have two Finale DXs and a Graco SlimFit3 LX across the back of our Model 3. It's the only way to get three across. Super tight but works. Seats are narrow and lightweight.

Comparison with Wayb Pico for travel
The Finale is less than half the price of the Pico and still weighs only 11 lbs. We took it on a plane and it fit down the aisle. Son said it was okay for the 2-hour flight but not super padded.
