the curtain stool by kim dong-gyum makes soft shapes from solid concrete

for his latest work, designer kim dong-gyum has taken ultra-high strength concrete to create the ‘curtain stool‘ furniture series. the project intends to break the public’s perception of the durable material by employing it to create small, sculptural-like products. as the name suggests, the concrete is shaped into a curved form at the bottom, mimicking the soft folds of a curtain.

to make the curtain stool, kim dong-gyum has utilized UHPC (ultra high performance concrete). this material boasts a compressive strength of 17,000 pounds per square inch (120 MPa) and is typically used for large commercial buildings due to its durability. however, as opposed to the straight, orthogonal forms usually cast, dong-gyu has used the material to create a soft, organic shape.

the curtain stool comes in a variety of colorways. from exposed grey concrete, to blue, pink and even marble, the project provides a simple piece that would suit any interior.
