Want to turn those Mario-loving couch potatoes into Mushroom Potatoes that stay healthy and slim? According to Tomonari Higuchi, president of Strapya Inc., which distributes the product, these Mushroom Chairs do just that: “They give kids good posture with the Japanese Seiza seating style that doesn’t allow the bending of the backbone.” These puffy rump rests are catching on big in Japan with “young women in their teens, 20s and 30s,” added Higuchi. “It’s also good for elders, as well.” For anyone who loves Seiza, Zen or anything about Japan/Japanese culture, these chairs come in four colors: brown, blue, pink and red. These chairs are featured on the hit Japanese drama “Hanayori Dango 2,” which is an ongoing weekly TV series in the Land of the Rising Sun.
