Double strollers are built to accommodate two - or three - children. There are two types of double strollers: inline and side by side. Inline strollers have the seats positioned in one line ie. on top of each other and side-by-side strollers have the seats next to each other. Both of these types of strollers can have a board attachment for the older child to ride in the back of the stroller. The best double stroller for you will depend on your particular situation and we're always here to help give you all the information you need to make the right decision for your family.
