Fans of the HandySitt portable seat will be happy to know that Minui, the company behind Handysitt, has just released the HandySitt chair. It can be used as a base for the portable seat, allowing the seat to serve as a highchair for children as young as six months, but it also serves as a standalone piece of furniture that does double duty as a stepstool and as a seat for older kids.The feet of the portable seat slide into pop-up hinges on the chair. Then a hidden magnetic system connects the steel arms of the seat to the chair. The top step of the chair can also be adjusted as your child grows. Add sleek Danish design to this functionality, and you've got a winner.
