Fastening in the direction/against the movement
In strollers with this function, the seat unit can be fixed in one of
two positions, to choose from: facing the parent (against the direction of movement) or facing away from the parent (in the direction of movement). Each option has its advantages: in the first case, the baby can see a familiar face and is less nervous, and when located in the direction of movement, it is more convenient for him/her to view the world around him/her.
Crotch strap
The presence of a separate
crotch strap in the design of the stroller. Only pushchairs with a bumper (see above) are equipped with such a strap: it is located vertically between the legs of a seated kid, preventing him/her from falling out by slipping under the bumper. In general, this design is similar in purpose to
three-point harnesses (see “Harness type”), however, in a stroller with a bumper and crotch strap, the child is usually less crowded. You should pay attention to the presence of this function when buying pushchairs.
Carrycot installation
The ability
to install a carrycot on the pushchair — a characteristic basket in which the baby can lie comfortably.
Carrycots are used mainly for very young kids (up to 6 – 8 months), who can not yet sit normally in seat units. And the possibility of installing such an accessory by definition is available in all universal pushchairs (see "Design"). Also, the replacement of the seat unit on the carrycot can be provided in pushchair models. In fact, such pushchairs are also universal – but they are not initially equipped with carrycots, and therefore belong to the category of pushchairs.
Car seat installation
The possibility
of installing a child car seat on the chassis of the stroller. This feature can be very useful on car trips: the car seat can be used both in the car and as a seat unit for a stroller, and the main seat unit can be left at home so that it does not take up space in the boot. Note that some models with this function are initially equipped with a suitable car seat; if it is purchased separately, you should pay special attention to compatibility with your stroller.
Handle height adjustment
Possibility
to adjust the stroller handle in height. This function allows you to optimally adjust the length of the handle to the height of the parent. It will be especially useful if the parents are of different heights, and each of them regularly carries a stroller.
Typically, height adjustment is carried out by lowering or raising the upper segment of the handle, and in advanced implementations
a telescopic mechanism is responsible for it. The retractable handle makes the stroller more adaptable to different situations and conditions. For example, it can be lengthened for more comfortable walking or shortened for ease of use in tight spaces.
Frame material
The main material from which the frame of the pushchair is made.
— Aluminium. The material used in the vast majority of modern pushchairs of all price categories. This is due to a number of advantages: aluminium is light and at the same time durable, it does not rust and is not afraid of moisture, it lasts a long time, it looks nice, but it is relatively inexpensive — somewhat more expensive than steel, but noticeably cheaper than more advanced materials like carbon.
— Steel. Steel frames are as strong as aluminium frames, and they are much cheaper. On the other hand, they are quite heavy, so steel is used less often in pushchairs.
— Magnesium alloy. Premium Material: Stronger and more durable than aluminium, just as lightweight, but at a significantly higher cost. It is extremely rare, in single models of expensive pushchairs.
— Carbon. Another high-end material: carbon fiber filled with plastic. This combination gives excellent strength - comparable to steel — at a very low weight. However, carbon is very expensive, and these advantages are rarely decisive for pushchairs — in most cases simpler materials are enough. That is why carbon frames have not become widespread.
— Plastic. Plastic itself is easy to manufacture and relatively cheap; it is also not as cold to the hands in cool weather as aluminium or steel. However, modern pushchairs very rarely have frames made of this material. The fact is that low-cost vari...eties of plastic are not strong enough for this; and high-quality varieties cost accordingly - their price is close to aluminium, or even higher.
— Fibreglass. In this context, "fibreglass" typically refers to glass fibers mixed with plastic filler. Unlike conventional window glass, glass fibers are flexible and strong. The plastic filler enhances durability by offering scratch and tear resistance. The result is a material that is lightweight and very strong. However, fibreglass is prone to brittleness, especially with point impacts, and is susceptible to abrasion. As a result, it isn't widely used in pushchairs.
Rear wheels without axle
Pushchairs in which the rear wheels are mounted on completely separate stands, without any additional bridge between them.
The main advantage
of rear wheels without an axle is that the legs of the parent following the stroller do not touch the bridge between the wheels. In addition, this feature slightly increases the mobility (allows the stroller to pass between the wheels lying on the road objects, without clinging to them with the axle).
Front wheels diameter
The diameter of the front wheels installed in the stroller.
At the same time, the front wheels are not as important for mobility as the rear wheels: for example, to overcome obstacles, the stroller is often lifted "on its toes" by tilting it towards itself, with only the rear wheels working. Therefore, the diameter of the front wheels may be noticeably smaller than the rear wheels. It should be noted here that the small size also has its advantages — the wheels are lighter.
Speaking of specific numbers, diameter
up to 15 cm is considered very modest,
16 — 20 cm — small,
21 — 25 cm — medium,
26 — 30 cm is larger than average and
more than 30 cm is large.
Rear wheels diameter
The diameter of the rear wheels installed in the stroller.
The larger the wheel — the better it overcomes obstacles and bumps, the more convenient it is to drive the stroller over mud, snow and other difficult surfaces. For the rear wheels these moments are most relevant: for example, when driving the stroller over obstacles, it is usually tilted towards itself, so that the front wheels are in the air, and the rear wheels have to overcome the obstacle. On the other hand, small wheels weigh less and are easier to move, they are better suited for flat surfaces. So choose a stroller on this indicator should take into account the roads on which it has to be driven. If you plan to move on flat floors, good asphalt and stroller ramps — it is worth choosing small wheels, up to 20 cm. For difficult terrain, driving on mud and snow, regular overcoming steps and curbs it makes sense to pay attention to wheels in 30 cm and larger. And the diameter of 20 — 30 cm is an average option — it is suitable if you have to ride mainly on flat surfaces, but occasionally there is a need to overcome obstacles.
