Style Athlete There is some degree of use. I think there are no problems with the function. I used it for a while, but it didn't go well with a newly purchased chair, so it has been stored at home. I will put it up for sale at a reduced price, so I would be happy if those who want to try it would purchase it. Size: Approx. W410 x D380 x H330 Weight: Approx. 1.1kg Weight Capacity: Approx. 120kg [Product Description] Style Athlete is designed with unique functions based on the theory of "chiropractic" to help you be aware of the correct skeletal position. By pursuing posture and gathering the commitment of top athletes who have been the proof of it, it brings out the original power of people and leads to a more active lifestyle. Thank you for viewing. Thank you very much.
