The TriMate (CC408) is an all-in-one seat that Safety 1st lists for rear-facing from 5 to 40 lb and 19 to 40 in., forward-facing from 30 to 65 lb and 34.4 to 49 in., and booster use from 40 to 100 lb and 43.4 to 52 in. The product page links no manual and gives no expiry or aircraft status.
On paper it matches the TriFit's ranges, with an 8-position headrest, a 3-position base, an infant insert and visible belt paths. The trade-off is that I cannot check its installation limits, expiry or aircraft certification without a manual. If those details matter before buying, the TriFit (CC407) lists the same ranges and links a user guide.
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. Check the date label on the shell before using a hand-me-down; every seat has an expiry.
| Mode | Child weight | Child height | Minimum age | Conditions |
|---|---|---|---|---|
| Rear-facing harness | 5 to 40 lb | 19 to 40 in | Not published | — |
| Forward-facing harness | 30 to 65 lb | 34.4 to 49 in | Not published | — |
| Belt-positioning booster (high-back) | 40 to 100 lb | 43.4 to 52 in | Not published | — |
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.

Safety 1st lists three modes: rear-facing at 5 to 40 lb and 19 to 40 in., forward-facing at 30 to 65 lb and 34.4 to 49 in., and belt-positioning booster at 40 to 100 lb and 43.4 to 52 in. The features are a one-hand adjustable 8-position headrest and harness system, a 3-position adjustable base, a soft infant insert, two removable dishwasher-safe cup holders, visible belt paths and a machine-washable, dryer-safe seat pad. The page says the seat meets the federal side impact standard and that actual fit may vary.

The TriMate page has no user guide link. That leaves the lower anchor weight limit, which base position each mode uses, how the harness is stored for booster use, the expiry period and aircraft certification unpublished online. I would read the manual and labels that come with the seat before installing it, and not assume another Safety 1st manual applies.

The TriFit (CC407) page lists the same three ranges: 5 to 40 lb and 19 to 40 in. rear-facing, 30 to 65 lb and 34.4 to 49 in. forward-facing, and 40 to 100 lb and 43.4 to 52 in. as a booster. It also lists an easily adjustable 3-position base, a 1-hand-adjustable headrest and harness system, a soft and plush infant insert and 2 removable, dishwasher-safe cup holders. It does not give a headrest position count. The linked user guide is the clearest difference.

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.
Safety 1st lists 5 to 40 lb and 19 to 40 in. rear-facing, 30 to 65 lb and 34.4 to 49 in. forward-facing, and 40 to 100 lb and 43.4 to 52 in. as a belt-positioning booster.

The product page does not say and does not link a manual. I would check the labels on the seat and the manual that comes with it.

Safety 1st does not state aircraft certification on the TriMate page. I would check the seat's labels and its manual before planning to fly with it.

Yes. Safety 1st describes the seat pad as machine-washable and dryer-safe, and the two cup holders as removable and dishwasher-safe.

Not the same model, but the TriFit (CC407) page lists the same ranges, 5 to 40 lb rear-facing, 30 to 65 lb forward-facing and 40 to 100 lb as a booster, with a 3-position base. The TriFit page also links a user guide.
