Maximum baby's weight
The maximum weight of the driver that the wheelchair can withstand without breakdowns and other troubles. Usually this indicator is indicated not for a one-time “trip”, but for regular use over a long period of time. At the same time, many models are able to endure a short-term excess of the maximum weight without visible consequences, but it is still not recommended to do this — it is possible that the structure will not break immediately, but its service life can be noticeably reduced.
Also note that it is worth choosing a gurney according to the maximum weight with a certain margin, and not only because the child is constantly growing. The fact is that manufacturers can indicate the maximum weight for simple conditions — a flat surface without bumps; when hitting bumps, the load may exceed the calculated load, even if the weight of the rider is within the normal range.
