IKEA has married LED lights with stools to create illuminant furniture, which might help those living in crowded flats save space. 
 The stool uses a built-in LED light source with a lifetime of approximately 20,000 hours. The 5W LED emits a warm white glow at color temperature of 3,000 Kelvin, and emits about 170 lumens of light.

 Four rechargeable batteries (AA 1.2V) come along with the stool, and can last for a minimum of two years. Charging time required is two hours, but will allow the stool to stay lit for five hours.
