Viewing window
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.
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.
Carrycot dimensions (LxW)
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.
Weight (complete)
The total weight of the assembled pushchair. 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 pushchair 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 pushchair type (refer to "Design"). Heavier pushchairs 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 pushchairs and transformers. Models weighing
16 – 20 kg are notably heavy, while those
exceeding 20 kg are rare and found among high-end double-seat pushchairs.
