Chinese design studio Neri&Hu design the unique Xi collection for Italian label Poltrona Frau. The Xi collection is comprised of frosty, blown glass lighting pieces that were designed to imitate a soft morning sunlight. The word "xi" translates to "the light of dawn" in Chinese, which indicates the exact time in the morning when the sun is about to rise. Hu explains that "xi" is very specific in the dictionary, indicating the time between 5:30 to 6:30 as a period where the sky exudes a special light. To the designers, the lamps indicate more than just a soft light, it aims to represent a concept of something intangible. Similar to a sunset, it marks a beginning and an end, whilst also representing cyclicality.
The Xi collection is comprised of a table lamp and two hanging lamps, combining signature Italian leather from Poltrona Frau, with blown glass from the Venetian. Every lamp has two different types of blown glass, with the upper part blown with ridged details and is translucent, then colored with hues of either amber, sapphire, emerald, or moonstone. The lower glass has a pearl finish or a frosty finish to give off the soft illumination.
