The Britax B-Dual is a stroller similar to the Britaxu B-Smart
, but with the possibility of adding a second seat to create a tandem. With the purchase of a travel bag, a carrycot or a car seat you can create up to 22 different combinations. However, you cannot add more than one full-featured carrycot or one car seat to the stroller. The lower seat will always face forward, you can pair it up with a soft carrycot for a newborn though. The second seat cannot be adjusted upright, it will always be partially inclined. That is why the stroller is more suitable for a younger and an older sibling.
