It is a modular seating capsule defined by curves nodding to lava lamps and London buses. The capsule became known for its playful look and nostalgic feel. Since then, the brand has launched new colorways to join the series along with a sculptural side table in collaboration with Parisian brand CAHU. Showcased at Milan Design Week this year inside Capsule Plaza, the T4 collection hit the spotlight. The sofas come in Pear Green, Licorice Black, and Cotton Candy Pink. The modular seating encourages lounging and gathering. This highlights the brand's aesthetic and approach to using [curved form](https://www.trendhunter.com/trends/smooth-sofa), adaptability, and color.
