I drove to TSC this morning to check this out. They had just 1 in stock, I liked it, and I brought it home.
The deck is just 1/2 in thickness but the wood is surrounded on all 4 sides by steel framing. The frame has 4 cross members underneath to support the deck plus a fifth cross piece that connects with the 2 main side rails. All in all I found the platform to be quite sturdy.
The TSC website says it has an adjustable platform height between 24 and 48 inches. The 48 max must be CYA on their part because it does indeed have a max platform height of 72 inches. I climbed up using the end rail while at the 6ft level and got a feel for the overall stability. It did not feel unsafe at all however I was on a level concrete surface. I'm sure I will need to use more caution if on gravel or grass, etc.
Their sale price ends tomorrow or maybe Sunday. For light-duty scaffolding, I would recommend it.
