RavenBC, it's a little hard to tell from that picture, but I'm 95% sure that is not a drop stitch floor. That stitching on the side has nothing to do with drop stitch flooring. With a drop stitch floor, it is super rigid (higher pressure) and you do not need a platform to stand on it. It is called drop stitch because of the joining of two pieces of polyester woven support fabric with thousands of fine polyester thread lengths.
"It can be inflated to rock-hard rigidity. You get hard-shell performance along with the easy transportation and storage of an inflatable."
A simple google search will show what it looks like.
