The KEER chair can be positioned in three different ways thus making up three different types of chairs: a stool, a side chair and a lounge chair. Each lightweight polyethylene piece is 20cm (8”) wide and can be connected to another by built-in neodymium magnets. This means the width of KEER is adjustable to the different positions. Two pieces are recommended for both stool and side chair and three pieces are optimal for a lounge chair. Additionally KEER can become a bench by connecting an even larger number of pieces.
