Convertible Car Seat Recommendations

[Sats27]

Hi,

I have an IS 250 and need to buy a convertible car seat. Any recommendations as I tried using the Evenflo Momentum and it was a tight squeeze?

Thanks in advance.

I'm having trouble finding a good convertible car seat fit for my IS250 too. Let me know if you find something. Please!!

I used to have a Britax--not sure which one. I never tried to install it backwards; I'm thinking that would be tight. Forwards was fine, though.
