How to make a concrete seat

Introduction
This concrete seat is 32" (800mm) long, 14" (350mm) wide, and stands 14" (350mm) high.
It is reinforced with wire mesh and weighs around 117 lb (53 kg).
Designing and writing about such a project is a lot more involved than simply making it for one's self.
A lot of thought has to go into the design and the method of making, so it can be explained in a way that readers are able to understand.
Thought has to go into the easy availability of materials, along with terminology.
Also taken into consideration is the type of tools that the average DIYer is likely to own.
This particular project took four takes before it was ready to put to paper.

Maybe make a few to sell!
There is more expense and time in the making of the form (mold) for the concrete seat, than in making the actual concrete seat itself,
however you only need to make the form once in order to make multiple seats.
It makes good economical sense to make more than one seat after taking the trouble to make the form.
Not including the form, the cost of making each seat is inexpensive in relation to a similar type of seat made from wood.
You basically only need a wheelbarrow of concrete mix, some reinforcing mesh, and some release agent, all of which can be obtained quite cheaply - and even more so in bulk. Each seat takes but a couple of hours to make and gets easier with practice.
Maybe there could be a couple of bucks in making and selling the odd seat or two....just a thought.
