Buy this seat!

This is my second time buying a britax one4Life from the baby cubby! My son is still using his at 4 so we knew my 1 year old needed the same one. This seat checks off all the things on my list for a great price.



Thank you so much for your review! We are so happy that you have found such a great car seat for your kids!

Peace of Mind

Jaycee was so kind and so knowledgeable when helping me pick out a new car seat for my baby. I asked millions of questions and she never made me feel like they were dumb questions. I now feel comfortable driving around in crazy Utah. Thank you Jaycee and Baby Cubby!



Jaycee is the best! Thank you for shopping with us!

Britax carseat

My overall experience was exceptional. When I first ordered the car seat, I was informed that the color I wanted was no longer available. The baby cubby kept in contact with me and made sure to give me other options. My order arrived in a timely manner and they were very professional! I will definitely be ordering again.

Great compact seat

The installation was very easy and I love all the features of the one4Life.



We love the Britax One4Life! We're so glad that this worked out for you!


Great experience buying from Baby Cubby

I was searching for a safe and easy to set up baby car seat. I fell in love with the Britax One4Life and the Nuna Exec but decided to go for the Britax because of the ease of setting it up as we have two cars and may use it in any of them. Baby Cubby was the the only seller that I did not even have to discuss with to give me a 10% off as first time buyer. The seat arrived on time and we are all happy with it.



We LOVE to hear this!! We are so happy that both you and your daughter love this seat!!!
