Design space: A safer high chair Product: BabyBjörn high chair Design: Ergonomidesign Territory: worldwide Accidents can occur when infants stand up and fall out of high chairs, or if they push with their feet against a dining table and the high chair topples over. According to the Swedish consumer agency Konsumentverket, about 800 high chair-related accidents are reported in the country each year. BabyBjörn, a Swedish manufacturer of children's products, wanted to introduce a safer high chair. Ergonomidesign's solution was to think of the chair's tray as a way of keeping the child secure, rather than using more conventional straps. Poorly adjusted straps can be a hazard if children wriggle out of them, or if adults fail to do them up properly. The integrated tray table is attached to a bar between the child's legs, and can be tilted vertically to allow the child to be placed in the seat. The tray table is then brought forwards and into a horizontal position. It is adjusted to fit snugly against the child's middle - which stops the child being able to stand up - and is secured in place with a twist-and-push safety button. As with some other high chairs, the tray creates a distance between the dining table and the child so it cannot be reached with the child's feet. The model went on sale in 2010 and so far BabyBjörn has received no reports of accidents.
