[S30]

Just like the balance beam, this is a simple high quality product. I bought this to help me spend more time in a squat position and it works. I spend time on my laptop or tablet.
It's made from a high quality plywood that looks good. I like the fact that it is packable - it comes apart so you can take it with you without taking up so much space. I will say that the tolerances on this are pretty tight (it looks like it was made with a CNC or laser cutting tool). So tight that it actually took a bit of effort to assemble it and it would only go one way and not the other. This was not a big deal for me - hence 5 stars. In fact, the tight fit means that when I move it around, it stays together.
