There are some key accessories that you will need to get the most out of your Britax B-Ready stroller.

2nd Toddler Seat

To transport two toddlers in the B-Ready, you will need to purchase a second car seat. Specifically, you will need the Britax 2nd Seat for B-Ready Stroller.

The second seat installs in seconds.  Note that you can fold the stroller with two seats attached.

This second seat sells for $140, and comes in all the same colors as the actual stroller.

Britax Chaperone Infant Carrier

If you have a young child still in a car seat, then you can attach either a Britax car seat or another car seat, including from Peg Perego, Chicco and Gracco, to your B-Ready stroller.  You can attach an infant carrier on its own, two infant carriers at once, or one infant carrier and one toddler seat.

If you do not already have an infant carrier, then an excellent choice is the Britax Chaperone Infant Carrier.  This is a very sturdy and safe car seat that is easily to install.  It is a big car seat, and heavier than most, which is the trade-off required for added safety.

The Britax Chaperone sells for $183.99.

Britax B-Ready Lower Infant Car Seat Adapter

If you plan to attach two car seats to your B-Ready, then you will need the Britax B-Ready Lower Infant Car Seat Adapter.

Note that when you attach two car seats to the B-Ready, the lower seat must be a Britax seat, and you must use this attachment.

The Britax B-Ready Lower Infant Car Seat Adapter sells for $79.99.

Britax B-Ready Universal Infant Car Seat Adapter

If you have another car seat that you wish to attach to your B-Ready stroller, then you can use the Britax B-Ready Universal Infant Car Seat Adapter.

This adapter works with the Chicco Key Fit, Chicco Key Fit 30, Graco Snugride 32, and Graco Snugride 35 systems.

The Britax B-Ready Universal Infant Car Seat Adapter sells for $46.
