Compared To

Compared to Graco Extend2Fit, the Safety 1st Crosstown is slimmer and cheaper but has a harder-to-tighten harness; some prefer Graco for ease of use.

vs Evenflo Revolve360

Evenflo Revolve360 is a rotating seat that is easier for loading but wider and more expensive; for slim fit, Crosstown is better.

  • Harness tightening is a common pain point

    We have this seat. I wanted to love it bc it’s one of the slimmest and cheap... The tightening strap is near impossible to tighten. The only way I can tighten it rear facing is by pulling it through the other side of the seat (like into the front seat). So I wouldn’t recommend it. Save yourself some frustration.

  • Recommended for slim fit and extended rear-facing

    I've seen the Safety 1st Crosstown Slim recommended a lot for convertibles with small footprints and ease of install. It’s cheap, slim, and has high rear facing limits. For a swivel, the Evenflo Revolve360 is great but wide. If you really need slim, go Crosstown.

  • Harness adjuster difficult even for older child

    I have a Safety 1st Crosstown and the harness adjuster is SO hard to tighten. I have to use two hands and it's a workout. My kid is 35 lbs and I struggle every time. I regret this purchase.

  • Acceptable movement per manual, but some find it excessive

    I have the same seat and get similar movement. I called Safety 1st and they said up to an inch at the belt path is acceptable. It's within spec, but it still freaks me out when I see it move. Just tighten as much as you can.
