besides the weight limit what is the difference between the SR30 &SR35?


Well-known member
My sister really likes the OB35 because if the leg room. I have found 2 different SR30's that are similar in pattern that she may like. Just wondering what the difference is between the SR30 and SR35, besides the weight limit.

Aslo which fits better 3 across? OB35, SR30 or SR35? She drives a 2 door Ford Focus so front to back space is an issues as well.

sr30 has less growing room than the sr35. its a narrow seat just like the regular SR's

the sr35 is really wide...
i dont know how wide the ob35 is but the sr30 would probably be the best bet for doing 3 across

The SR35 base has a lockoff, while the SR30 base does not. The SR30 CAN be used with the 35 lockoff base (if you go to purchase a 2nd base, the 32/35 base is the only option unless you call Graco) but the one it comes with does not have the lockoff. If you're installing the 30 base in a LATCH position, no biggie, but if you're using a seat belt with a locking retractor, it usually causes the base to tip and it's a pain, so it's way easier to have the lockoff.

The Keyfit is shorter front - back than both the Onboard and the Snugrides though.

The SR35 is the least three across friendly. It has a flared base. The onBoard 35 and SR30 have rectangular bases.
