General design of the pushchair.

In addition to traditional varieties — classic models (with a carrycot) and pushchairs (with a seat) — nowadays you can also find universal pushchairs, which are 2 in 1 and 3 in 1, transformers and pushchairs for sports purposes. Here is a more detailed description of each variety:

— Pushchairs. Pushchairs designed for the sitting position of the kid. The seat for the baby in such pushchairs is called a seat unit; in fact, it is a seat of a special design. In some models, this seat can tilt almost horizontally, which gives the little passenger the opportunity to take a nap. Nevertheless, all pushchairs are intended for more or less grown-up kids who are able to sit up independently — that is, not younger than 6 — 8 months.
Also note that in this category there are the possibility of installing a carrycot. In fact, such models are universal (see below); but if the carrycot is not initially included in the delivery, it is customary to classify the pushchair as a pushchair.

— Jogging. A type of pushchairs (see above) designed for parents who value an active lifestyle: a jogging pushchair can be used not only when walking quietly, but also when jogging. Such pushchairs are usu...ally equipped with three wheels of rather large diameter, and also have a large width of the chassis (see below); all this gives additional stability and passability, including on uneven roads. In addition, the design may include specific features for added comfort and safety, such as a strap that fixes the parent's hand on the pushchair handle or an additional brake that activates when the pushchair is released from the hands.

— Universal. Pushchairs often come with at least two (or even three) interchangeable units: a lying carrycot for infants, a seat unit for older babies, and sometimes a Group 0+ car seat. Parents can choose which unit to use on the chassis. This option provides convenience throughout the baby's pushchair years, starting with the carrycot for the first 6-8 months and transitioning to the seat unit. However, these universal pushchairs are pricier and less space-efficient than transformers with similar capabilities. On the flip side, separate carrycots and seat units are more convenient and reliable.
It is worth taking into account that some universal models can be supplied in alternative options — for example, " carrycot + car seat". So, when buying such a pushchair, it does not hurt to specify the set of accessories supplied with it.

— Pushchair-transformer. Transforming pushchairs allow the seat to convert seamlessly from a carrycot to a seat unit and vice versa, offering the same versatility as universal models. Unlike universal pushchairs, transformers don't require rearranging the main unit for this reconfiguration, providing several advantages. Firstly, the main block's format can be changed anytime, even on the go, without the need for separate seat units or carrycots. Secondly, the integrated carrycot takes up less storage space compared to two separate units.

— Classic. Pushchairs that are equipped with carrycots only; some also allow the installation of a seat unit, as in universal models, but if such a unit is not included in the kit, the pushchair is considered a classic. Recall that carrycots are intended mainly for children under 6 – 8 months old, who are not yet able to sit normally in the seat unit; in other words, this type of pushchair is suitable mainly for the smallest kids. That is why the "classic" nowadays is not particularly popular.

The carrycot carry handle for carrying is mounted on the carrycot and makes it easy to carry it from place to place — for example, if you need to remove the carrycot for cleaning and then put it back. The handle can have a different shape — in the form of an arc attached to the sides of the carrycot, in the form of a hood cutout, etc.

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.

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.

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.

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.

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.

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).

The type of wheels installed on the pushchair.

The most popular in our time are rubber wheels, including air-filled ones. Plastic wheels are used mainly in inexpensive pushchairs to further reduce the cost, while gel ones, on the contrary, are considered a very advanced option. Polyurethane wheels and EVA foam-filled wheels are also widely used. Here is a more detailed description of each of these varieties:

— Rubber. Rubber solid tires, found in many modern pushchairs, are popular due to their affordability, quiet operation, and smooth ride over bumps. While less effective on uneven surfaces compared to air-filled and gel wheels, solid rubber tires are cost-effective, low-maintenance, damage-resistant, and suitable for various wheel diameters, including small ones.

— Air-filled. Air-filled rubber tires, commonly featured on pushchairs, offer a softer ride and facilitate easy maneuvering on uneven surfaces and high curbs. Despite their higher cost, they require periodic maintenance to ensure proper pressure and protection against cuts or punctures. However, users find air-filled wheels manageable, as they are thick and less prone to damage.

— Plastic. Plastic wheels, commonly featuring both tire and rim made from this material (thou...gh some have metal rims), are known for their simplicity and affordability. However, they lack durability, reliability, and effective vibration dampening due to their hardness. Typically found in low-cost pushchairs with small wheels designed for flat surfaces.

— Gel. Wheels similar in design to air-filled tires (see the relevant paragraph), but filled not with air, but with a special gel. The main advantage of this option is its insensitivity to small punctures and cuts: coming out, the gel in the tire in contact with air almost instantly solidifies, effectively sealing the damage. In addition, such wheels are virtually maintenance-free — they do not need to be inflated. The disadvantages of gel tires include high cost and somewhat higher rigidity than air-filled tires (although in terms of softness of running such wheels are still noticeably superior to rubber and even more so to plastic ones).

— Polyurethane. Solid polyurethane tires offer excellent maneuverability, shock absorption, puncture resistance, and durability. They are unaffected by extreme temperature changes and are cost-effective, making them a common choice for various pushchair types.

— EVA. Wheels made of microporous foam rubber, specifically EVA material, offer high elasticity, excellent cushioning, and wear resistance. Lightweight and puncture-resistant, these wheels provide a smooth pushchair ride. However, they may stiffen in cold winter weather.
