About Toma Hōpa

He hōpa a Toma i hoahoatia mō ngā wāhi noho. I ahu mai te āhua o Toma i te whakaaro o te takai i te tūru katoa ki te wāhanga kotahi o te kākahu, pēnei i te kākahu kirēpe. Ko te hua ko tētahi mata haere tonu me ōna piko ngohengohe e karapoti ana i te tangata e noho ana. I whakamahia te kākahu whātororo hei whakatutuki i te mata piko matatini, he uaua ki te hanga. Ko te rahi o Toma he 1580 mm te whānui, 950 mm te hōhonu me te 850 mm te teitei. Kei te tūhura te hoahoa i tētahi āhua herekore ake mō tētahi taonga whare noa.

Unique Properties
This sofa was born from the act of wrapping it in a single piece.
It has become a unique sofaa with undulations.This project began with the question: could we express the commonplace piece of furniture that is the sofa in a freer form? The idea expanded from the thought that wrapping it in a single piece of fabric, like crepe, might yield an interesting shape, leading us to arrive at this form.
