What car seat will attach to the pram? Will the comfort fix car seat work with it?
The Lacrosse is an older model, so I am not sure I'd risk trying a new car seat type on it, even though - yes, I am pretty sure it WILL fit the Lacrosse since the attachment system is the same. It is good to say that the Lacrosse was sold as a ready-made Shop'n'Drive travel system with the matching Zero Plus Comfort 0+ car seat, so an older variation.
Again, I will say that it should be compatible, but you never know with older models - there might be a glitch. With the Zero Plus Comfort 0+ car seat, you have the compatibility granted.
