I had this frame. it is made very well. but i had a problem with the smoothness of the wood... they told me to just sand it myself. the 'tubes' not bending is a bit misleading. you have to buy your own conduit at Home Depot, etc. the benefit of this frame is that you can have the conduit cut to any length you need... i only had room for 9.5 feet, so had mine cut that way. Sit down?... depends on how you set it up... i don't recommend it. you really have to move around a lot when quilting on it. some people use a saddle seat rolling chair. the pantographs would lay on the 'table' that is underneath the carriage. mine came with a groovy board [pattern] and i usually had it turned over for a smooth table. i never really used the groovy board patterns... but had to cut the two pieces shorter to fit my 9.5'. i was very happy with it, but sold it with my entire set up when i moved from minnesota. i made my own leaders from non-tear poly fabric... worked great.
