It is a nice and study looking stool however we did have some issues putting it together.  A note to the manufacturer...most of the screws should really be 45 or 50 mm long as two of the screws holding the legs to the platform needed to be switched with two longer screws from the back.  The notches on the lower leg should be a bit deeper to give a bet grip as over time they may become an issue.  It appears sturdy now it is all put together and hopefully it will last.
