Making it for Madi
Madison de Rozario in her custom TiLite ZR
In the past two blogs have been discussing TiFit and the importance of a chair made to fit the individual. Today, we will be looking specifically at how we worked with Madison De Rozario to design a TiLite ZR made for her and her lifestyle.
To start the process, we met with Madi to find out what her life looks like: what does she love to do, what does she like about her existing chair, and what would she change if she could? Some of the key things about Madi mentioned included: her love for her dog (Sebastian), that she travels a lot, that she wants her chair to stay looking good despite her hectic lifestyle, to be “minimalistic”, and to be ultra-light, but very strong.
Despite Madi having an extremely strong upper body, her pelvis requires only a 285mm (11”) rear seat width. She really wants the front of the seat to be narrower, which follows the contour of her body.
So, we specified the chair to have a 37mm (1.5”) taper from midway down the seat to the front of the seat.
We worked out that, based on her arm length, 480mm (19”) is the best rear seat height for Madi, and that a front seat height of 508mm (20”) gave her adequate stability while allowing her to get under tables and desks. The seat upholstery to footplate height of 300mm (12”) is quite short in relation to her floor to seat height, and Madi wanted this to look as clean as possible, so Madi chose an open loop titanium footplate which needed to be custom made for her chair. We used the same rear wheel axle position as her existing chair and measured the overall length of her existing chair as this worked perfectly for her. Based on her frame length, overall length, and wheel base length the required front angle was worked out, using Computer Aided Design Technology, to be 83.5 degrees.
Madi also wanted her feet to sit nice and snug in her footplates, so measuring the width of her favourite shoes we specified a footrest width of 178mm (7”). Finally, Madi wanted her chair to be narrow at the front castors, so she can get into tight corners and use a “3 wheel” technique for going down the aisle of aeroplanes (with someone supporting the weight of the chair by holding the rigidiser bar at the back of the chair, one of the rear wheels is removed. This makes the chair narrower and able to be rolled down the aeroplane aisle, negating the need for an aisle chair. Because Madi’s chair is small, it also fits on the overhead locker of most planes). To achieve this, we specified a front castor width of 362mm (12.5”).
TiLite’s commitment to truly custom building the Z and T series chairs from the ground up allows for chairs like Madi’s to be made to fit her body and lifestyle perfectly.
