The Grow and Go (CC409) is a non-rotating all-in-one seat: rear-facing harness for 5 to 40 lb and 19 to 40 in., forward-facing harness for 30 to 65 lb and 34.4 to 49 in., and booster for 40 to 100 lb and 43.4 to 52 in. It is aircraft certified with the harness and expires after 10 years.
The Grow and Go suits a family that wants one seat from newborn to booster without paying for rotation, and may fly with it in harness mode. The trade-off is a simpler seat with 3 recline positions, installed through a different belt path rear-facing and forward-facing. The Turn and Go 360 lists the same limits but rotates and has 5 recline positions.
A research summary of Safety 1st’s published specifications and manual, read . Not a hands-on test or a crash-safety rating.
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.

Rear-facing, install with the lower anchor belt or the vehicle belt through the rear-facing belt path, and do not use the tether. Store the tether hook on its storage attachment. Forward-facing, attach the tether whenever anchors are available and use the forward-facing belt path. The lower anchors are allowed up to 55 lb; above that, install with the vehicle belt. Do not use both methods at once. If the seat moves more than 1 in. at the belt path, the manual suggests pulling tighter, reinstalling, or trying another position or method. Some vehicle belts need the locking clip.
The seat has 3 recline positions. Rear-facing uses Position 3 or 2, and forward-facing and booster use Position 1, fully upright. For children 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. who sit up unassisted, use the top line. When using the lower shoulder harness slots for smaller children, the head and body pillows must both be used and the headrest must be in its lowest position. Harness covers are optional and should come off if they stop the chest clip sitting correctly.
As a booster, do not use the harness or LATCH. Store the lower anchor belt and tether, and use only the vehicle lap and shoulder belt. Keep the booster belted even when empty, and stop if the child's ears are above the headrest or the head is less than 5 in. below the roof. On aircraft, use it only with the internal harness, in a window seat, and only on a forward-facing aircraft seat. Wash the pad cold on a gentle cycle with the harness cover strips closed, no bleach, and tumble dry on low for 10 to 12 minutes.
The Turn and Go 360 page lists the same three modes and limits: 5 to 40 lb rear-facing, 30 to 65 lb forward-facing and 40 to 100 lb as a booster. The differences are design. The Turn and Go rotates in all three modes on an attached base, has 5 recline positions and a 10-position headrest, and uses tension indicators and a built-in lock-off. The Grow and Go instead has a 3-position recline and a QuickFit harness. Neither page publishes a width.
Each campaign naming this family was read against this model’s numbers and build dates, and none covers it. Still check your seat’s model number and date of manufacture before use, especially on a used seat.
Rear-facing 5 to 40 lb and 19 to 40 in., forward-facing 30 to 65 lb and 34.4 to 49 in., and booster 40 to 100 lb and 43.4 to 52 in. Reaching any one limit ends that mode.

The manual says it is certified for aircraft use when used with the internal harness. It is not certified as a booster, because aircraft seats do not have shoulder belts.

The manual says not to use the lower anchors for a child over 55 lb. Install it with the vehicle belt above that weight, and never use LATCH in booster mode.

No. The manual says not to use the tether in rear-facing mode and to clip the hook to its storage attachment. Forward-facing with the harness, the tether must be used when anchors are available.

Both list the same three modes and limits. The Extend 'n Ride LX page adds a ComfortPlus footrest that works in all 3 modes and provides up to 7 in. of additional leg room rear-facing.
