Your room’s name is an adaption of the idiom “Put the Pedal to the Metal.” In a literal sense, this meant to press an automobile’s accelerator to the vehicle’s metal floorboard. Figuratively, this phrase suggests fast-paced performance, at full capacity, pushing ahead rapidly and recklessly.
Idioms can be phenomenal idea generators. The word mettle originally meant metal. In current usage, and in a metaphorical sense, the word conveys qualities of courage, determination, fortitude, and strength of character, in other words, a person's mental, physical, and spiritual toughness.
Your room’s idea evolved further to explore the visual and textural contrasts between the sensuality of nature, as represented by the petal and the influence of industrialization, technology, and urbanization on the use of metal craft in art, architecture, and design, characterized by the word mettle.
For you and for us, your room inspires going all in and all out in all we do.
