Stool with an accordion-shaped seat plays a musical note when you sit on it! - Yanko Design

The Xia Stool, or as I call it, the Philharmonic Whoopie Cushion Chair, is a fun little seat that uses an accordion-shaped cushion to turn the human action of sitting downwards into something rather surprising and entertaining. Seat yourself downwardly on the Xia Stool and it instantly emits a note, concertina in an allusion to traditional Portuguese music.

Designed by Soraia Gomes Teixeira, a Portuguese designer from Oporto, the Xia Stool aims at revitalizing the common seating object through the power of audio. The accordion-shaped absorber provides an aplenty visual warning to the user, priming them to await a sound every bit they sit, so they're never caught unawares. Even though the piano accordion-shaped cushion acts as a visual indication, information technology'south still incredibly fun and entertaining to actually have the seat meet your expectations, letting out a friendly honk as you sit! Soraia mentions, "[The] Xia Stool is a fun object that makes people smiling and unleashes their imagination."

The Xia Stool is made from wood, Burel fabric, and 100% Pure Sheep Wool. Each stool emits a high-pitched 'A' note, although it would be fun if different stools played unlike notes, creating chords as multiple people sit down together!
