Ok,
I just looked at the link you provided. This is the same inexpensive bench I sell. It is not well padded, in fact it is very hard and if you notice, there are only three holes to adjust the height in the middle of the X and if you go to the highest, the width of the legs gets too narrow and tippy. I would not recommend this to a musician who needs to use this all the time. Again, it is well suited for a child say under 5ft tall.
