Design Rationale
Who, What, Why, Where, When, How
Who: My client(s) will be the TMS Lower School toddler house students (approximately 3-5 years old in age).
What: The problem is that my client is in need of a new seating solution that promotes flexibility and and creativity in the classroom environment. Thus, I will be creating and designing a comfortable, creative, and innovative (these 3 traits as part of my client's needs) solution that can be used by said students.
Why: The Montessori curriculum involves lots of movement and collaboration as part of its learning curve. Especially with the rebranding of TMS to Lauremont schools (which puts more emphasis on the Montessori part of the TMS identity), the TMS faculty is likely trying to modernzie other parts of the school besides just the name (in which case being the seating plans).
Where: The product will be for the TMS Lower School and will be designed at the TMS School Design Course.
When: The product will be designed and created between September - November 2023.
How: For this project, I will be using the following applications:
Sketchup - CAD
Adobe Illustrator - Compositing/Presentation

SEATING SOLUTION:
Materials
-Office chairs (which are designed to have long lifespans/to be frequently used) are typically made with leather, fabric, plastic, and nylon. These materials are also cost-efficient in terms of large scale production; These are thus materials that I should consider incorporating into my design
-From a survey conducted by Fashinza in 2017, 76% of people believe that linen chairs are the most comfortable in terms of chair upholstery fabrics.
-Microfiber is also one of the most eco-friendly and sustainable fabrics available in the market. It allows the skin to breathe easily, and is highly resistant to long-lasting stains.
Function/Structure
STRUCTURE: Chairs typically consist of 4 legs, a slightly angled seat, and a back rest (for extra comfort). The seat is sometimes cushioned to provide extra comfort for those who are sitting for long periods of time (ie: office chairs).
FUNCTION: Generally, chairs are used to provide support and comfort for the seated person's body and arms.
Ergonomics
Definition (according to Mr.Bank): The study of how we use and interact with a product or system, or the “fit” between humans and the products they use.
-Kids should be able to sit all the way back comfortably in the chair with their feet flat on the ground and knees at a 90 degree angle. The chair should support the spine considering the children are sitting down 50% of the time (according to their teachers) to avoid injury/discomfort.
Anthropometrics
Definition (according to Mr.Bank): Common measurements of people separated by age and sex. The table below shows the anthropometric data for the bodily measurements of preschoolers/first year primary school students (data for students around the age of 5 years old):
CLIENT (ACCORDING TO MY PRIMARY RESEARCH):
How do 3-5 year olds behave?
After having toured the lower school and observed how the kids interact with their chairs, I can conclude the following:
The kids like to kick their feet when sitting on the chairs
Often lean back when they sit
The chair should be easily moveable so they can tuck their chairs in easily, also slide their chairs on the carpet to entertain themselves
Like to rest their feet behind the legs of the chair when sitting; My design should thus be able to support their weight
The kids sit on the edge of their chair most often
Move and turn when they sit
Sit within close proximity to table
When on the edge of their seat and leaning, they are at high risk of falling; It is crucial the chair be stable enough to support their weight
Kids play with their chairs and sometimes pick them up; They should be lightweight in case they accidentally hit someone/something when doing so
What are their general needs?
-To be able to move easily and efficiently around the classroom environment
-To better be able to work with their peers
-To promote creativity and completing work in a timely manner within the classroom; This thus requires a source of motivation, as a boring chair design with dull colours will be less inspiring to the kids than a vibrant, colourful chair design would be.
What are their seating needs?
-A comfortable, easily accessible seating solution
-A lightweight, easy to move design that is easily adjustable to better pertain to the individual needs/wants of each kid
-A seat that is able to be used for long periods of time throughout the day
What are their ergonomic needs?
-A cushioned seat for extra comfort (especially considering the long durations the kids are sitting in the chairs for)
-A foot rest at the bottom of the chair so they have somewhere to place their feet as opposed to kicking their feet or leaning them on the legs of the chair (safety hazard)
-Weights on the legs of the chair to ensure that when the kids sit on the edge of their chairs and lean (very common occurrence during visit to lower school), they do not fall
-A stain-resistant material considering toddlers are prone to spilling what they eat/drink on their chairs
General Montessori Beliefs/Principles - Which are relevant to the design of a chair?
A PREPARED ENVIRONMENT: A prepared environment not only means having the appropriate materials (eg: pencils, paper, colouring materials) that are needed by Montessori students during day to day activities in the classroom, but it also means providing students with an environment that promotes creativity and inspires them to put out their best work. Chairs are one of the most basic parts of the classroom and are thus important in determining how the kids work.
FREEDOM WITHIN LIMITS: Having full creative freedom is an important part of the Montessori curriculum. A new and creative chair design that inspires students to test the limits of what they are able to produce.
COLLABORATIVE LEARNING: Flexible seating solutions allow for students to take ownership of their learning. A change of seating allows for students to be engaged in collaborative learning in a different way than before and inspires them to approach and work with each other more.
PRINCIPLE NEEDS:
Cost
-Microfiber chairs are 60% cheaper in mass production than other materials (such as linen and various types of wood)
-Using less expensive materials (while still being durable and long-lasting) will ultimately lower the price of producing my chair design in a large scale setting
Safety
-Sharp edges or points that could cut a child along the edges of the chair are a safety hazard
-Moving parts that could harm a child's finger, toe, limb or head by: pinching, crushing, trapping (Hence, a swivelling chair and adjustable arm rests are unsafe for the young audience)
-Should be the appropriate height of toddler; If too high, child may fall from chair thus resulting in a potential injury, especially considering the kids often sit on the edge of their seats (as evidenced by my primary research)
-Chair should be lightweight to avoid injury if kids knock them over or pick them up and move them (avoids possible accidents)
Durability
By definition, durability is the ability of a material to withstand wear despite continual/frequent use.
-Microfiber and canvas are two of the most durable and soft furniture fabrics.
-Durability is not only about how well the furniture functions, but also how well it fits the style, mood, and identity of the space, in which case being a classroom
Comfort
My chair should be able to support the neck, back, hips, and spine. This reduces pressure on the body, which is important considering the toddlers spend long durations of time sitting on their chairs throughout the day (again according to my primary research). An ergonomically curved back helps achieve this.
The initial problem is that the TMS Lower School community is in need of a new seating solution that will instill the core values of the Montessori curriculum into their students from a young age. From my secondary research, I concluded that the solution to this problem is an ergonomically designed (meaning a chair that supports the spine and allows students to sit with their feet at a 90 degree angle), cushioned (for comfort, considering students spend 50% of the day sitting according to teachers), sturdy chair that accomodates anthropometric measurements. Therefore, my chair will be a brightly-coloured (contributes to aesthetic appeal) microfiber (stain-resistant material; according to teachers, spills are very common) chair with steel legs that have weights at the bottom (to avoid the toddlers possibly falling from sitting on the edge of their seats), with a curved back to accomodate ergonomic seating, arm rests, and a foot rest at the bottom to accomodate the children's requests. Using microfiber is also ideal because it is lightweight and thus more flexible to move around the classroom, helping encourage collaboration and creativity: 2 of the core Montessori values. I will accommodate anthroprometric data in the 50th percentile, which describes average measurements.
