We were surprised as it looks like the cube boxes with a lid on it but me and hubby both tried it out and it held our weight with no problems.  Bought three of these to go with a vanity for our girls and they worked fine, height was good.  Top is pretty comfy and firm, might not wanna binge watch tv sitting on it, but good for a vanity.  There is storage room in the seat so that was a bonus.
