ONE&ONE / Child carrier.

When going out with their baby, parents carry the baby in a stroller or a baby carrier. The existing strollers cause considerable inconvenience in case of using an escalator, stairs, or a rest room. Even when they are foldable, a parent should hold the baby or use a separate child carrier. To remedy such a problem, a detachable child carrier was installed on the seat of a stroller, combining the usability of two products. With a baby sitting on the child carrier, the child carrier can be attached to and detached from the seat conveniently by means of rails and hooks.
