Some strollers are a combination of the two. Still other infant strollers have seats that can face rear or front and may be removed to double as a travel bassinet. Strollers are available from singles through quads. Some are made to be used by children of the same age and some can be used by children of different ages. If your children are different ages you may choose a model where only one seat reclines or a sit or stand style, where your toddler has the option of sitting on a shelf seat facing the rear or standing on a platform facing the front.
Different people have different stride lengths.
Try to have whomever will be using the stroller the most try it out before you buy it. Feet knocking against the back of the stroller can be uncomfortable for adult and stroller occupant. Some strollers come with adjustable handles, which may put the stroller at a more comfortable arm length and keep the feet from hitting the back. For inside locations such as malls or areas with smooth sidewalks, you may simply want the stroller that folds the most compactly and opens the easiest. Umbrella strollers are light weight, compact, and ideal for travel with older babies and children.
