The Disney Baby Easy Elite Slim (CC406) is a 3-mode all-in-one seat. The manual lists rear-facing 5 to 40 lb and 19 to 40 in., forward-facing harness 30 to 65 lb and 34.4 to 49 in., and high-back booster 40 to 100 lb and 43.4 to 52 in. It must not be used more than 10 years after manufacture.
It suits a family that wants one seat from a 5 lb newborn to a high-back booster and does not need a backless mode. The main trade-off is a simple 2-position recline: reclined with the booster kickstand stored for both harness modes, and upright with the kickstand out for booster use. The closest sibling, the EverSlim 4-in-1, lists the same harness limits on its page but adds a backless booster mode, a 5-position recline base and a 10-position headrest.

This seat covers 3 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.
| Mode | Child weight | Child height | Minimum age | Conditions |

A child must meet every limit for the mode they use. The labels on your seat and its manual are the final word.
Every install is a fit between one seat and one vehicle. Read both manuals, and use a free inspection station if anything is unclear.
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.

The manual gives two rear-facing methods and says to use only one: the vehicle belt (lap/shoulder or lap only) or the LATCH lower anchor belt, never both. The tether stays stored rear-facing. For a child 5 to 30 lb and 19 to 34.3 in., the bottom level line must be parallel with the ground. For 30 to 40 lb and 34.4 to 40 in., and only if the child can sit up unassisted, the top level line applies. The seat should not move more than 1 in. at the belt path. The child's head must be at least 1 in. below the top of the headrest, and the buckle goes in the 1st or 2nd slot.
Forward-facing with the harness covers 30 to 65 lb and 34.4 to 49 in., and the top of the child's ears must stay below the top of the headrest. The manual says not to use the lower anchors for a child over 55 lb (24.9 kg); above that, install with the vehicle belt. When the vehicle has a tether anchor, the tether must always be attached and tightened in forward-facing harness mode. The forward-facing level line must be parallel with the ground, and the vehicle seat back must be upright. If a vehicle headrest gets in the way, the manual points to the vehicle owner's manual to see whether it can be removed or adjusted.
For booster use, the harness system is stored and the accessories are removed, except the cup holders. LATCH is not used in booster mode, and the manual allows only the vehicle's lap and shoulder belt. A round tab on the side releases the booster kickstand, which puts the seat upright; the seat back must sit flush against the vehicle seat. The shoulder belt threads through the belt-positioning guide in the headrest and should cross the center of the shoulder. The child's ears must never be above the top of the headrest, and the manual says not to use the booster if the child's head is less than 5 in. below the roof. Keep it belted in even when empty.
The headrest and harness move together: fully loosen the straps, squeeze the adjustment handle, move the headrest, release the handle and check it is locked. For the lower positions, the bottom of the headrest pad folds up under the middle section. The harness strap must sit at or slightly below the shoulders rear-facing, never above. The seat pad comes off without removing the harness. Machine wash it separately in cold water on a gentle cycle, with no bleach, then tumble dry separately for 10 to 12 minutes on low heat and remove it right away. Harness straps are spot cleaned with warm sudsy water. The cup holders twist out and are top-rack dishwasher safe.
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.
The manual lists rear-facing 5 to 40 lb and 19 to 40 in., forward-facing harness 30 to 65 lb and 34.4 to 49 in., and booster 40 to 100 lb and 43.4 to 52 in. Each mode ends when the child outgrows any one limit or the child fit requirements.

No. The product page lists three modes: rear-facing, forward-facing and a belt-positioning booster seat for 40 to 100 lb and 43.4 to 52 in. There is no backless mode.

Yes, with the internal harness. The manual says to install it in a window seat, on forward-facing aircraft seats only, and that it is not certified for aircraft use as a booster.

The manual says not to use it more than 10 years after the date of manufacture, which is on a label on the side of the seat. It also says to replace the seat after a moderate to severe crash.

Safety 1st's page says the design fits 3 across the back seat of most vehicles, and also that actual fit may vary. It does not publish a width, so I would measure the back seat and check the other seats before buying.
