The presence of a separate crotch strap in the design of the stroller. Only strollers 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.

A window made of transparent or translucent material, built into the hood that covers the cradle or seating unit. In the version with a walking block, the viewing window is usually located so that the parent can see the baby directly while moving, without being distracted from controlling the stroller. In cradles, the parent can see the child through a window by approaching the stroller from the side of the hood (that is, on the opposite side of the handle); implementations with a window in the front hemisphere of the hood are less common. In addition, a baby lying in a cradle can usually see the outside world through the window (primarily the sky above the stroller). The viewing window can be made in the form of oilcloth or a mesh mosquito net, through the holes of which air freely penetrates, but insects and small debris raised by the wind are retained.

The main material from which the frame of the stroller is made.

— Aluminium. The material used in the vast majority of modern strollers 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 aluminum frames, and they are much cheaper. On the other hand, they are quite heavy, so steel is used less often in strollers.

— 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 strollers.

— 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 strollers — 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 aluminum or steel. However, modern strollers very rarely have frames made of this material. The fact is that low-cost varieties of...plastic are not strong enough for this; and high-quality varieties cost accordingly - their price is close to aluminum, 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 strollers.

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.

— Seat unit. A seat unit serves as the child's sitting area, suitable for use from 6 – 8 months onward when the child transitions from lying in a carrycot to sitting comfortably. All stroller types feature seat units (see "Design"), except for classic and transformer models. Classic strollers inherently use a carrycot, while transformers use a unique device known as a "carrycot-transformer" (see below).

— Carrycot. A traditional carrycot is a basket with high sides in which the child is lying down. Such baskets are intended for children in the first months of life - usually up to 8 months, no more; from an older age it makes sense to use a seat unit (see above). Carrycots are used in all types of strollers, except for pushchairs and transformers (see "Design") - the first type is completed only with seat units, the second uses the so-called " carrycot-transformers" (see below). A special kind of traditional carrycots are carrying carrycots (they are also described below).

— Carrying carrycot. A variation of the carrycot (see above) designed to be easily carried separately from the stroller. To do this, the design provides an appropriate handle. At the same time, not every carrycot that has a carrying handle (see above) belongs to this category of accessories: "carrying" are called only those carrycots that initially allow long-term carrying in the hands and...have various design features that facilitate such transportation.

— Carrycot-transformer. In fact, it is a carrycot, which, if necessary, can be turned into a seat unit for a child who can sit up.

— Car seat. A specialized seat designed for the safe transportation of small children in cars is essential for compliance with safety regulations in many countries. Car seats are typically provided with strollers for babies up to 12 months and weighing up to 13 kg. However, a separate seat for older babies must be purchased. Before buying, it's important to check the specifications of the car seat, particularly the method of attaching it to the car.

— Foot cover. A cover designed to protect a child's legs in a stroller from wind, cold and bad weather. While blankets or improvised solutions can be used for the same goal, complete covers offer more convenience as they securely attach to the stroller and stay in place during movement. Additionally, if needed, a blanket can be placed inside the cover for extra warmth. It's worth noting that many strollers, lacking this accessory, allow for separate purchase. This accessory is primarily used with seat units, whereas carrycots rely on a leg-area canopy with a similar function, though it's not classified as a cover.

— Rain cover. A waterproof cover that protects the child in the stroller from rain, snow and strong winds. Usually such a cover is made of transparent material or has transparent inserts — so that the baby can see the world around, and the parent can follow the baby. Rain covers for strollers are also sold separately, but if such an accessory is included in the kit, you do not have to worry about compatibility.

— Mosquito net. Mesh with small cells, which can cover a child sitting in a stroller. The cells allow air to pass through, but trap mosquitoes, midges and other harmful insects, as well as small debris raised by the wind; such protection is especially useful during evening walks in the warm season, as well as when going out in the countryside.

— Bag / backpack for things. A separate bag that is usually hung on the handle of the stroller. In such a bag you can keep various useful small things that need quick access: food, toys and hygiene items for the baby, parent's documents, etc. In most cases, the bag is removable, which provides additional convenience. Note that for some models, initially not equipped with a bag, such an accessory can be purchased separately. And some models are equipped with a backpack — a more convenient option for use.

— Shopping compartment. A device in the form of a basket or container installed at the bottom of the stroller - under the cradle or seat unit. This compartment is convenient for storing purchases and other things that do not require quick access while walking. At the same time, larger and heavier items are placed in the basket/container than in a bag for things (see above); and the low position improves the stability of the stroller. The shopping compartment can be either open or closed. The first option is found everywhere, the second - mainly in elite models (and such strollers can be supplied with two baskets: open and closed, or in different colors). The capacity of a closed compartment is often smaller, but the contents in it are securely hidden from prying prying eyes and protected from dust, dirt and moisture. Compartments for purchases are made from a wide variety of materials: plastic, metal mesh, fabric, etc. Soft materials are generally lighter, but less durable, hard ones are reliable, but can interfere when overcoming curbs and other obstacles.

— Cup holder. A stand on the parental handle to hold a glass or bottle with a drink - for example, milk for the baby or water for the parent.

— Hand strap. Strap on the handle of the stroller, which the parent can put on his hand. This reduces the risk of dropping the stroller: the strap is likely to keep it close to the parent, even if the arms are fully unclenched.

— Hand muff. An accessory that can come in handy when strolling in the cold season. The muff is attached to the handle of the stroller; if desired, you can hide your hands in it so that they do not freeze in the cold. At the same time, the design of the muff is such that it does not interfere with fully holding the handle and driving the stroller.

— Cover for stroller. A protective cover designed for storing and transporting a stroller during non-use hours is typically made from soft materials. It primarily protects the structure from dirt, direct sunlight, and moisture to some extent. While it offers symbolic protection against mechanical damage, more substantial safeguarding would require a case made of rigid materials. However, the need for such intensive protection is rare in practice. Soft covers are favored for their lightweight nature and minimal storage space when folded, making them the most popular choice for strollers. Overall, a complete cover tends to be more convenient, practical, and reliable compared to makeshift packaging.

The distance between the side wheels of the stroller; this generally corresponds to the overall width of the stroller. If the front and rear widths are different, the greatest distance is indicated, usually on the rear wheels; the same wheels are used to measure the width of three-wheeled models.

In general, the wider the chassis, the more stable the stroller is and the more difficult it is to tip it over. On the other hand, greater width can cause problems in tight spaces such as narrow hallways and doorways, elevators, etc. The narrowest modern strollers have a width of up to 45 cm, the widest — more than 70 cm (these are mainly models for twins or triplets , where two seats are side-by-side). Models 46 – 50 cm are also considered quite narrow, a width of 51 – 55 cm can be called small, 56 – 60 cm — medium, 61 – 65 cm — more than average, 65 – 70 cm — large.

Dimensions of the carrycot provided in the kit.

Partly the rule "the bigger the better" works here: a large carrycot gives a good reserve for the period of growth of the baby, in winter you can put the baby dressed in warm clothes in it, and in summer the extra space in the carrycot provides good ventilation. On the other hand, large carrycots are more bulky, weigh more and cost more.

The width of the seat installed in the stroller.

When selecting a seat, focus on the seat width, considering the child's build and allowing space for future growth, rather than the overall dimensions.

The total weight of the assembled stroller. For universal models (see "Design"), this paragraph usually indicates the weight with the seat unit installed: such an accessory is used for a longer time than the carrycot, therefore its characteristics are considered the most important. In addition, the difference in weight between cradles and walking blocks usually does not exceed 700 – 800 g (there are exceptions, but quite rarely).

Comparing similar models, a lighter stroller may offer more convenience, but it often comes at the expense of reliability or a higher price compared to a relatively heavier counterpart. It's important to note that weight varies based on the stroller type (refer to "Design"). Heavier strollers provide stability, reducing the risk of tipping over. The lightest models, weighing less than 5 kg, refer to pushchairs and single-seat ones. Models in the 6 – 10 kg are also mostly pushchairs, including variations for twins. The 11 – 15 kg range is standard for universal strollers and transformers. Models weighing 16 – 20 kg are notably heavy, while those exceeding 20 kg are rare and found among high-end double-seat strollers.
