Weight limit
The maximum weight of a child that the swing can support without negative consequences in any position and in any mode of operation. A heavier child should not be placed: even if it does not break immediately, there is no guarantee that this will not happen at some point later, with unpleasant consequences for the child.
Foldable
The ability
to fold the swing for storage and transportation — in this sense, foldable models are much more convenient than non-foldable ones, because they take up less space. On the other hand, foldable swings are less durable and more prone to wear and tear; this does not affect the safety of use, but it can affect durability, especially with frequent folding/unfolding.
Backrest tilt levels
The number of fixed positions in which the adjustable backrest of the swing can be installed (refer to "Backrest tilt adjustment"). Any adjustable backrest has at least two positions — lying and sitting, and the more levels of tilt — the more options you have for customizing the swing to maximize your baby's comfort.
Volume control
The ability
to adjust the volume of the built-in speakers in order to customize the sound of melodies for a lulling effect or for waking and playing.
More features
—
Timer. A timer that switches off the automatic rocking mechanism (refer to "Automatic rocking") after a certain time. Thus, knowing the approximate time your baby falls asleep, you can set the timer and not worry about the rocker continuing to rock unnecessarily while your baby sleeps.
—
Removable table. The presence of a removable table top in the design of the swing. Such a swing can play the role of a high chair; in addition, the table top can be useful for games.
—
Player connection. A function similar to a music box (see above) — with the difference that the sound source is not the memory of the box itself, but a player connected to the swing.
—
Vibration unit. The mechanism that provides the vibration of the seat unit — this plays the role of a massage for the child, and also creates a relaxing effect.
—
Arc with toys. A structure in the form of an arc or bracket above a swing, on which various toys are suspended. They can be used to play or to distract the baby (for example, to stop crying). The arcs are often made removable, and the brackets are also swivel.
— Lighting effects. Multi-coloured flashing lights that can cheer up or distract the baby (especially in combination with sound).
Finishing material
The material with which the swing is finished externally. The absolute majority of modern models use fabric — this material is soft, pleasant to the touch, easy enough to clean and allows you to create different colors.
