Y 系列休閒椅嘗試於 Y 字樣裡加入不同素材，除了凸顯特徵外，更能減輕視覺的厚重感。兩側的Y式樣與座椅的深色 SONO 搭配形構了整張椅子的精神。

異材質的搭配更使得休閒椅的姿態更有張力；冰冷的鐵管於扶手部份特別鑲入有溫度的深色木材，視覺上是若隱若現的一體感，實際休憩觸摸時卻能感受到創作者的細心與體貼。

 

Y4 Easy Chair features a SONO sandwich in the y structure. A part of handrest made with Sono is inserted between the metal tube that provides a warm touch for your arms.
