This is an investigative design. Intended to fit an imaginary scenario,  which included its own set of restrictions. The scenario in which the  stools would fit is an outdoor scene where people gathering would want  an experience as close as possible to the bare, natural conditions that  one would find at a spontaneous meeting place. While in truth the  location would be planned and functional, and one could benefit from  having resources around, such as seating. So that every aspect would  be intentional and considered, while remaining simplistic and primative  and not showing the design effort behind it. Especially, we wanted to be  as low-to-the-ground as possible without actually having to sit directly  in the dirt. Something similar to sitting on tree trunks placed around a  bonfire. Imagined in a purely natural setting such as on a beach. And  the initial inspiration came from children sitting on dusty playground,  circling their teacher, and a thought that they could be sitting on  something at least, if a design existed that could be cheaply and easily  made with what was around them.        Remembering falling into piles of cut hay as a child, and the way that the bunch would give, and cushion, and let you just sink into natural comfort, I turned to  grass stalks as a comfortable yet supportive material for the seating. It was also plentiful around the children’s playground, and an un-used free resource. In  building the example stool i realized that stalks larger than those of grass would be a better solution. (There is an unnecessarily large amount of time spent per  stool to harvest what is actually quite a lot of grass that must be sorted, cut, etc..) And reed, or waste bamboo branches might be more efficient alternatives. But  sticking to the specific local circumstance, the example stool uses grass. Thatching grass may work, but i collected Hyparrhenia cymbaria which has thicker  stalks.

  Grass Bench-Stool Minimalist and simplistic, using natural and local materials. A bunch of grass, and binding framework, to sit on.
The shape of the strapping to ‘tie’ the bundle together had to be the simplest, cheapest, and incredibly easy to produce (no power tools, smelting, melting, or  precision necessary). Yet still had to achieve all of the characteristics of an optimal design. For instance the stool needed to consider meeting with a flat  substrate, and the strapping needed to avoid interfering in the meeting of the stool and the sitter. And the minimal strapping has to perform every element of  creating form in the piece, but to do so while being reduced to nearly nothing. The process to achieve this is as follows.  A ‘two-way’ U-shape (in the x and y co-ordinates directions) is created by bending 6 mm mild steel rod by hand. The completed loop is joined at the  meeting ends with an overlap that is bound (or welded if one wants to cheat a bit). Grass or reeds are held into the “U” shape strapping by a straight bar  which hinges loosely on one end and hooks in place over the U-frame at the other. The ‘hinge’ loop and hook are cold bent into the rod around a round form.  The grass stuffing can easily be replaced, and ‘building’ the stool is as easy as laying the filler in place and clamping it down with the bar. The shape of the  strapping and the position of the clamping bar re-inforces the bundle the most in the centre, where the user will exert their weight.   The resulting stool is a springy cushion of a seat that is stable with a flat base. The stool brings the sitter very low for a ‘grounded’ feeling, but with a  little more comfort and dignity than sprawling in the dirt. The user is also put in a very natural sitting position. If the stools are being used around a fire, this  posture presents both the legs and body to the warming radiation. The primal atmosphere of an open fire at ground leve, and being seated around it, very  much suits the intentions of this stool. Though it highlights the obvious flamability of the dried grass. However this in turn highlights the low investment into a  stool and the expendibility of one of these pieces. Having one burn would be a very minimal loss, especially since the steel strapping component could simply  be re-used to re-create the stool. In fact the ephemeral nature of the raw grass material is a part of what makes it fit into a very raw setting.   Besides the naturally available grass or reed, the stool uses only one ‘industrial’ material which appears sparingly in the design and is cheap and easy  to work. The stool is therefore one step removed from the natural state of the grass as one might find it, and this fine line is crossed only by the most minimal  of strapping. Using this steel rod transported to the stool’s point of use with ease due to its uncomplicated shape in the raw material form, the stool can be  produced on-site. So that its simplicity translates not only to environmentally friendly materials in its structure, but also reduced packaging, transport costs,  and disposal concerns.
