I was skeptical that this could be a stable thing really, but after some wrestling with me I decided to try it the folding time, and what can I say, a really comfortable and functional chair for occasional racer .... Where one thing perhaps interfere, but it happens to be a bucket seat and therefore, it would be only an ergonomic proposal to the manufacturer, please build a an adjustable headrest, that would be great, not that would disrupt it with his head against the padded leaning headrest but it is just not perfect, which is now whining at a high level and for the price, you really can not go wrong with the chair .... :-)
