Cactus Chair is an experimentation to investigate the effect of visual data to the user's experience. The existence of the Barrel Cactus gives a temporary discomfort, even though the user knows that the cactus behind the glass is not a real threat.
The chairs are real and available for $3,000 if you're not comfortable making your own out of an old aquarium. Unfortunately, I'm gonna pass. You see, I actually enjoy sitting on cacti. It's like having 10,000 lovers at once.
