In this day and age of modularity fittings, it only makes sense to invest in products that can go beyond their obvious function. For example, the Monocart looks to be a simple child buggy, but as the child grows and out-grows the simple pleasures of being pushed around in a chair, making it a multi functional extends the useful life of this cart. It becomes a cart for wheeling groceries or a stroller; even a gardening stool. How about that!
