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.
Chassis width
The distance between the side wheels of the pushchair; this generally corresponds to the overall width of the pushchair. 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 pushchair 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 pushchairs 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.
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.
Seat width
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.
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.
