Question: What is the horizontal length of the scaffolding . . . or what is the span in feet that it covers?
Document: (when crouched)Mine came with one wheel that was defective as the brake lever is crooked making it difficult to lock.Also this does not have any adjustable height legs for uneven ground nor any feet that are not on rollers.The available safety guard cost more than the scaffold.
I have used this scaffold to wax our Motor Home, it's excellent! Very easy to assemble and with the large wheels, easy to roll around and put it where you want it. The wheels lock so that is an excellent safety feature. I would give it 5 stars if they provided a bar to secure the lower section when you are up at 6 feet.
I've been using this scaffold for a couple of weeks now while I remove plaster and gypsum board from a wall that is 11 feet high. I'm only 5' 6&#34; and this scaffold has made the job so much easier and safer than using a ladder. The scaffold is a little wobbly when the platform is set above 5 feet, but not enough to cause a problem.
Purchased two stands for painting high walls in home. Putting the stands together was very easy and simple. To stack, I did it without the assistance of anyone by using a 10 feet ladder to place the parts on the lower stand one at a time,  climbing on the lower stand to put them in place. Don't forget to purchase and use the outriggers when double stacking the stands and prior to installing the second stand on top.
Suggest you buy the guard rails for more security. Would be a 5 star product if it didn't rock and was able to replace the side rail pins with bolts. Also, not sure if the stand will hold 1000 lbs as advertised, I could hear the wood platform cracking under my feet the first few times I used it but no longer there after a few uses. There are several braces that support the wood flooring of the stands which appears to do a good job.
This scaffolding works great. It can be used on stairwells with the bucks set to different levels.
Better than no scaffolding, but slightly concerningly rickety. It really needs side extensions to feel stable. Still better than being up a ladder for some jobs.
I have two of these scaffolding units and they are very good for the money. They are especially good to use indoors where you can roll. I highly suggest getting the outriggers if you plan to own more than on set of these for stacking! Great item and a very good price!
After searching several sites for used  scaffolding, up poped up Amazon with this offer, i could not believe my eyes, i had to call to confirm it was real. Indeed it was every thing i expected and more, and the free shipping was icing on the cake. THis was actually a surprise gift for an artist friend, see absoultly loves it. Thanks Amazon
Got this thing for an exterior painting project. Project never materialized, but I must say, as a commercial painter, I'm glad I finally "kicked down." For this scaffolding unit serves itself up as a very purposeful tool. One in which serves me very well in multi-specific applications. FYI-----the color is blue, not yellow.
Answer: no
