First, the appearance chair with his higher and wider record is not a gimmick. The child has better seating, non-negligible parameter to put it at ease and in ideal arrangements for its needs.
Meanwhile, the pot ensures complete stability and a wide flared base (for that matter, so avoid the risk of spilling the contents of the jar on the floor!). The latter is accompanied by a grip tape, ultimate bulwark against any risk of sudden destabilization of the pot.
In addition, the pot is in two parts, thereby removing only the part where the child poops, which is much more convenient, both for emptying and for washing.
On the design side, there is the rather sober atmosphere of manufacturer: gray and white colors, no frills except the little teddy brand on the front of the pot, in short, nothing transcendent. The advantage is that the pot blends in anywhere.
All remarks made above may seem trivial for simple pot child. Nevertheless, for having tried other more conventional (and less expensive), this one truly is in the high end as it provides better assurance at all levels, for parents and for children. And this is not trivial!
