Hi,

I have noticed on some pictures or a video that the DXRacer Formula seems to have elastic bands along with cushioning in the backrest and not much else. That seems impressively close to what I'm looking for. But I have seen product pics of a cut open AKRacing where they have a steel frame with relatively tightly fitted parallel metal struts in the middle of the backrest. It's not completely "wooden", as some others by default, but apparently noticeably firmer than the DXRacer. Would you confirm this?
