When looking from a bubble you should make sure the ring is a continuous welded ring and that the bubble is blow out to a wider dimention than the steel ring. You do not want a bolted together ring as most of the Chinese bubble chairs have. In addition the chairs coming out of china are mostly sold with pictures stolen from Inmod.com or eero aarnio, and do not look much like the product you will receive. Don't be fooled by the chinese knock off bubble. You will not be happy with it, they are made with the wrong curvature of the acrylic and are not comfortable to sit in. Keep in mind... you get what you pay for..
