Krabat Pilot
From their website:
Krabat Pilot actively helps the child to raise its hips, so that it can kneel and be inspired to crawl. The lifting movement is dynamic and changes all the time while the child is crawling. Good details make the product user-friendly, safe and easy to manoeuvre. Tough colours and a design that signalises movement, speed and positive feelings motivate the child, support system employees and, not least, the child’s parents...
