How the onBoard Slide Infant Car Seat featuring SafetySlide Base installs
- Rigid LATCH
- Rigid LATCH (base). Rigid connectors click straight onto the vehicle's lower anchor bars, which removes the strap slack that causes loose installs.
- Belt lock-off
- Built-in belt lock-off (base). A lock-off clamps the vehicle belt so you do not have to switch the belt's retractor into its locked mode.
Every install is a fit between one seat and one vehicle. Read both manuals, and use a free inspection station if anything is unclear.
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.
- Certified for aircraft use, so it can travel as a seat rather than checked baggage.

Is the onBoard Slide Infant Car Seat featuring SafetySlide Base recalled?
NHTSA currently lists one campaign naming this Safety 1st family: 23C002000. A campaign names a family, not always every build, so check your seat’s model number and date of manufacture against the campaign itself.
I have not reviewed these campaigns for this model yet, so shopping links stay paused here.
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.
- 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.
