Who is the Disney Baby Pronto! Belt-Positioning Booster Car Seat for?
The Disney Baby Pronto! is a belt-positioning booster for children 40 to 100 lb and 43.4 to 57 in. It works as a high-back booster with an adjustable headrest, then as a backless booster with the same limits. The manual says not to use it more than 10 years after manufacture, and it is not certified for aircraft.
Reasons to consider it
High-back and backless modes at 40 to 100 lb and 43.4 to 57 in
A 2-position backrest (upright and semi-reclined) to sit flush with the vehicle seat
A slide-out cup holder on the side of the seat
A pad that is machine washable and dryer-safe
Things to weigh up
The linked manual is Cosco-branded and partly image-based
No LATCH, so it must stay belted even when empty
Lap-only and inflatable seat belts cannot be used with it
Not certified for aircraft use, because aircraft seats lack shoulder belts
My take on the Disney Baby Pronto! Belt-Positioning Booster Car Seat
The Pronto suits a booster-age child who needs a headrest to guide the shoulder belt now and a backless seat later. The trade-off is that the linked manual is a Cosco Pronto guide, it gives no headrest position count, and Safety 1st publishes no width or weight. The Store 'n Go Sport has the same 40 to 100 lb and 43.4 to 57 in limits and adds a storage drawer.

Who the Disney Baby Pronto! Belt-Positioning Booster Car Seat fits
This seat covers 2 stages, and a child has to meet every limit of the stage they are in. Safety 1st gives it a 10-year life from the date of manufacture, so check the date label before using a hand-me-down.
Belt-positioning booster (high-back)40 to 100 lb · 43.4 to 57 in
The seat’s own back and belt guide route the vehicle belt across the shoulder, and the sides give the child something to lean on when they sleep.
Backless booster40 to 100 lb · 43.4 to 57 in
Only the base is left, so the vehicle seat has to support the child’s back and head, and the belt guide sits at the hip.

Will it fit your car?
Safety 1st does not publish a width for this seat, so measure your back seat and compare it with the seat in a store before buying.
Check your vehicle manual for lower anchor positions and any head-restraint rules.
Rear-facing seats need front-seat room: try the install behind the driver before you commit.
Not certified for aircraft use: plan on gate-checking it or using a different seat to fly.

What to know before you live with it
Headrest and backrest adjustment
The manual says the booster has multiple headrest positions but gives no count. To move it, push down on the top of the headrest while pulling out the adjustment lock, then release the lock and pull up and down to confirm it has locked. The headrest must always be used with the backrest. The backrest has 2 positions, upright and semi-reclined, and the semi-reclined one is only for getting the booster flush against the vehicle seat back. Adjust the headrest so the shoulder belt-positioning guide sits slightly above the child's shoulders.
Place the booster forward-facing, flush against an upright vehicle seat back. The lap portion of the lap and shoulder belt goes under both armrests and across the hips, not the stomach. The shoulder belt goes under the armrest on the buckle side only and across the center of the shoulder, not the face or neck. In high-back mode, the ears must not be above the booster's headrest; backless, they must not be above the vehicle seat's headrest. In both, the child's head must be at least 5 in below the roof.
To go backless, press firmly on the backrest release tab, rotate the backrest back until it lies flat, and lift its hook out of the base. The headrest and backrest must both come off before the full pad set can be removed; the pads are held by elastic straps under the seat bottom and on the headrest. Machine wash the pads separately in cold water on a gentle cycle without bleach, then tumble dry separately for 10 to 12 minutes on low heat and remove immediately. Do not use the booster without its pad.
Is the Disney Baby Pronto! Belt-Positioning Booster Car Seat recalled?
No campaign in the current NHTSA child-restraint data names this model family, and I have not run a separate review for it. Check your seat’s model number and date of manufacture before use.
No. The manual says to use only the vehicle's lap and shoulder belt, never a lap belt alone, and to keep the booster belted through the belt-positioning guide even when unoccupied.
How does the Pronto compare with the Store 'n Go Sport?
Safety 1st lists the Store 'n Go Sport at 40 to 100 lb and 43.4 to 57 in in both modes, the same as the Pronto. The Store 'n Go Sport adds a pull-out storage drawer under the seat and extra storage on one side, along with a built-in cup holder.

Before you buy
Weigh and measure your child. The limits above are the manufacturer’s, and a child has to meet all of them for the mode they will use.
Confirm the exact version. Colors, retail exclusives and model numbers change limits more often than you would expect; Safety 1st lists 2 colors of this seat.
Read the manual before you buy, not after. It is linked above and holds the fit rules, the install methods and the expiry.
Check recalls by model number and date of manufacture, and register the seat with Safety 1st so you hear about the next one.
