Quick response

Shelli F.

Ordered a gate prior to this one, UPS lost it on route. I reached out to Kidsy via email and they secured a refund from UPS. Was hesitant to order again, but I couldn't find the gate at a more reasonable price. 2nd order arrived with no issues. Gate is sturdy and the dog (Husky) hasn't gotten through it (he's an escape artist). Quick delivery from start to finish.

Yes, it is FAA approved for use in harness mode on airplanes.
Does it fit three-across in a compact car?
Often yes, it's 17-18 inches wide and can fit in many three-across setups, but installation may be tricky.
How does it perform in crash tests?
Mixed: some independent tests show below-average results, but it meets federal standards.

  • Car seat that will last from 3yo to 8yo?

    User asks for a seat lasting from ages 3-8. Tranzitions is recommended as a lightweight option that can be used on planes (harness mode) and is narrow for three-across. OP later updates they bought it and found it perfect for travel and daily use.

  • Graco Tranzitions is a harness booster - the same as a FF harness seat?

    CPST-certified commenters clarify that the Tranzitions is a forward-facing only harnessed seat that converts to a booster later. Praised for its narrow width and low price point, but noted it can be difficult to install in some cars.

  • Booster Seat: Graco Tranzitions 3in1 works great!

    Owner of a GR86 sports car confirms the Tranzitions fits well in the small back seat. Installation was challenging but manageable. Appreciates the narrow width and how well it tucks against the seat.

  • Graco Tranzition - yay or nay?

    Post asking for general opinions. Responses are mixed: some CPSTs say it's not their first choice due to crash test concerns and installation woes, but acknowledge it works for narrow spaces and budget. Others still recommend it as a lightweight travel seat.
