Comparison Valco Baby Snap 4 vs Peg Perego Si

— Book folding system. In strollers, this system involves connecting frame parts along a common axis, resembling closing book pages when folded. Despite being somewhat more complex and heavier than umbrella strollers, book system offer versatility, suitable for various stroller types. They work well with both walking seat units and carrycots, accommodate different handle types easily, and significantly reduce height when folded, unlike umbrella structures.

— Umbrella folding system. In the unfolded position, the frame of a stroller, with its umbrella mechanism, appears as a front wheel support inclined backward, extending to a top handle, and a rear wheel support attached to it, standing vertically. During folding, the rear support pivots at the attachment point and aligns with the front support. Unlike book folding system, the front support remains rigid and doesn't fold independently. Umbrella strollers got their name from the handle — which is curved, like an umbrella handle.
The advantages of this type of mechanism are low weight, low cost and quick unfolding/folding. On the other hand, the umbrella structure is not well suited for carrycots, which is why it is used mainly in strollers and individual universal models. In addition, curved handles are somewhat less convenient than solid handles (the latter are also found in similar designs, but much less frequently).

The ability to adjust the position of the footrest, on which the legs of the baby in the stroller rest.

A similar ability is found in some strollers, transformers and strollers of universal strollers (see "Design"). The footrest itself is an inclined surface attached to the front edge of the seat. Adjustable footrests are those in which the angle of inclination can be adjusted; in many models, this footrest can even be set horizontally. This makes it possible to choose the most comfortable position for the baby's legs in different situations.

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 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 strollers 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 strollers except classic strollers (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 strollers 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 stroller 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 stroller is as smooth and soft as possible, which contributes to the comfort and deep sleep of the child (and the parent to drive...the stroller is much easier, especially on uneven surfaces). Secondly, the carrycot on such a stroller can be rocked back and forth, lulling the baby. On the other hand, such systems are poorly suited for stroller 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 stroller. 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 stroller, you have to press hard on the handle.

— Is absent. Strollers without depreciation are not suitable for uneven surfaces: in such conditions, the stroller 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 strollers 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 strollers rock less on smooth, wave-like uneven surfaces.

The ability to install a carrycot on the stroller — 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 strollers (see "Design"). Also, the replacement of the seat unit on the carrycot can be provided in pushchair models. In fact, such strollers 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.

— Classic. U-shaped handle (or similar), which is a kind of frame. It is slightly less comfortable to hold with two hands than a double handle, but can be comfortably held with one hand.

— Double. A pair of separate handles without a bridge between them. The handles themselves are usually curved so that the parent's hands resting on them are in the best, most comfortable position. At the same time, double handles should preferably be held with two hands; it is much more difficult to handle them with one hand than with a classic handle. In addition, it should be noted that this option is considered the most suitable for pushchairs (see "Design"), while for strollers with a carrycot it is not very suitable.

— Universal. A design that is a combination of the classic and double handle described above. This allows the parent to choose the option depending on the situation: for example, it is more convenient to hold the stroller with two hands by the "horns", and if one hand needs to be free - you can take the single (classic) handle. At the same time, such a choice is not really necessary for everyone, and universal handles are more complicated and expensive than specialized ones, so they are much less common.

— Round. The handlebar can have a different design: in some models it is an oval loop mounted on a long b...ar, in others it is a kind of "steering wheel" on a frame above the hood. Whatever the case, in some models such a handle is a round: it is directly connected to the front wheels, and when you turn the handle, the wheels turn to one side or the other. This noticeably improves maneuverability, but complicates the design and increases its price. However, there are also simpler designs, where the round handlebar differs from the classic handles only in shape. All these nuances should be specified for each model separately.

Possibility to adjust the stroller handle in height. This function allows you to optimally adjust the length of the handle to the height of the parent. It will be especially useful if the parents are of different heights, and each of them regularly carries a stroller.

Typically, height adjustment is carried out by lowering or raising the upper segment of the handle, and in advanced implementations a telescopic mechanism is responsible for it. The retractable handle makes the stroller more adaptable to different situations and conditions. For example, it can be lengthened for more comfortable walking or shortened for ease of use in tight spaces.

A carry handle or strap makes it easy to transport or lift the stroller. Typically, the handle is located on the frame of the product and provides a convenient place to grip the stroller when folded. Similar tasks are assigned to the belt - with the only difference that with its help you can usually hang a load on your shoulder or behind your back, freeing your hands.
