Sturdy and looks good. There should be more support video for the longer extension size. It is necessary to drill extra holes. Also the center support should be a centimeter longer to meet the wall parallel to the side frames and ground. There was an extra piece not listed on the parts or shown on the video that was for extra support on the top frame. At least thats what we decided.  We had to drill holes in the frame to get it centered. Read the comments that follow the video. There are good suggestions and pointers. As long as you are reasonably good at putting things together, this is a good project but not for the faint of heart.
