Depreciation
The depreciation theme is designed to absorb shocks and bumps from uneven road surfaces. The most popular nowadays are models with
spring systems; you can also meet the shock absorption of the
articulated and
double types, and in quite a large number of pushchairs this function is absent at all. Here are the main features of each option:
— Spring type. Depreciation systems based on classical springs mounted on individual wheels. They are used in all types of pushchairs except classic pushchairs (see "Design"). The simplest models use a single set of springs, while more advanced models may include additional comfort features such as SAS shock/vibration absorption technology. Whatever the case, depreciation systems of this type are simple yet practical, efficient and reliable.
— Articulated type. The type of depreciation used in pushchairs with carrycots - classic, universal, transformers. The frame, on which the carrycot or seat unit is installed, in such models is attached to the base of the pushchair with the help of special bridges, which play the role of depreciation. As bridges can be used belt hinges, such systems can also refer to the articulated. Anyway, this type of depreciation is excellent for carrycots. First of all, the pushchair is as smooth and soft as possible, which contributes to the comfort and deep sleep of the child (and the parent to
...drive the pushchair is much easier, especially on uneven surfaces). Secondly, the carrycot on such a pushchair can be rocked back and forth, lulling the baby. On the other hand, such systems are poorly suited for pushchair frames with swivel front wheels; and the failure of one absorber leads to tilting of the carrycot.
— Double. This term most often refers to the spring systems described above with additional shock absorbers on the frame of the pushchair. Such systems help to maximize vibration reduction and can approach articulated systems in terms of efficiency (see above). On the other hand, the softness of the suspension can be inconvenient when overcoming curbs and other bumps: to raise the front wheels of the pushchair, you have to press hard on the handle.
— Is absent. Pushchairs without depreciation are not suitable for uneven surfaces: in such conditions, the pushchair will be shaken violently, which creates both discomfort for the baby and inconvenience for the parent. On the other hand, such models have advantages over pushchairs with depreciation. First, due to the lack of unnecessary parts, they are much cheaper, and the design itself is as simple as possible and at the same time reliable. Secondly, without depreciation, it is easier to overcome curbs and other obstacles: to raise the front wheels, it is enough to push a small pressure on the handle. Thirdly, such pushchairs rock less on smooth, wave-like uneven surfaces.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.
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.
