Great for infant/ toddler doubles mode

We used this for the first 6 months when our second child was born. It worked really well to put our baby closest to us and our toddler in the seat he was used to. The only issue we had with this product was that it needed to be removed before we folded the stroller up in order to maintain the compact size. This wasn’t difficult to do or much of a hassle for us so i would definitely purchase this adapter again.

No purchase needed IF you already have a Britax car seat

This lower anchor bar fits most car seat brands but didn’t work with our Peg Perego 30/30 so we decided to return it and just put the Britax car seat (we HAD TO purchase it specifically to go with our B-Ready Stroller and put the Peg Perego car seat and single stroller in the garage ) on top and bought the second seat to use on the bottom. This configuration works the best with 2 kids under two (18 month old and a 3 month old) until the youngest gets bigger then we will have him in the lower positioned second seat and our daughter up top. If there are any first time parents reading this and want the most out of their B-ready stroller I highly suggest buying a Britax car seat first so when you have more kids you won’t need to buy a new car seat or this lower infant adaptor bar because the Britax b safe and chaperone car seats snap into the top seat area of the stroller. The only additional thing you would need to buy is a second seat and sometimes Amazon has deals where if you buy the b-ready stroller you get an accessory for free which is what happened with us and we saved some money. Hope this helps even though I went all over the place writing this lol.

Works great

Works great. Highly recommend if you have multiple children and need to put the car seat on bottom. Worked perfect with the car seat adapter for my chicco.

Exactly what I needed!

I absolutely love my Britax B Ready! My son is 2 and I’m expecting my 2nd child in 2 months, and this is going to make out stroller perfect for 2 little ones!

Works better than I would have guessed.

We had our second kid – bought the B-Ready stroller so we could one day expand. But we were both always worried we’d be kicking the kid in the lower seat when using this. Not the case – we have the Britax Infant Car Seat down there now and it allows for enough room for me to comfortably (6 foot male athletic build with a long stride) to still push the stroller around the zoo for long periods. We’ll see when we put the toddler seat on someday, because that doesn’t curve upward like the car seat.

Surprised how well this works

For our second child we decided to find a dual stroller solution. We really like the "B-Ready" system. I was surprised how well this was installed and how stable everything works. Very Happy.

Great Product

Easy to use, and so nice to have as “extra” to the stroller. My 3 year old doesn’t use a stroller anymore- however we did allow her to use it while we were on vacation and walking around a lot. WIth this piece, we were able to make the stroller into a double, and put my infant daughter underneath. My 3 year old loved the fact that her little sister was riding “right behind her” 🙂 This product made our trip much easier.

Easy to install

We have the britax b-ready stroller and this car seat adapter is super easy to install and use with our britax carseat. Whenever it is not in use we take it off.

Works just as it should

Best stroller and set up by far especially for twins!! My fourth stroller and last stroller. Love it. Simple to use.

Must have for baby #2.

I wish the arms were a tad longer, the car seat canopy gets a little squished when rear facing. Also, if it were a few inches longer, we could stick our bassinet on the bottom. MThat said, I think this is the only attachment we need with children 2.5 years apart. My oldest loves to walk, so I imagine he will be fine giving up his toddler seat in 6 months or so. We also bought a Joovy Bumprider stroller board (love it!) so he can ride and share his stroller with little brother. I’m able to attach both the board and this car seat adapter at the same time.
