There are some products that make you wonder why someone didn’t think of that before. QuarttoLino is one of those products. QuarttoLino is a children’s high chair that has three extra functions in addition to its core function of allowing an infant to sit ergo-nomically, correctly and safely at the dining table. It can be converted into a rocker, a small children’s table with a chair, a small staircase or a large, low-level chair by simply changing the side screws in just a few simple steps.
