Also good: even creaks with my 110kg and nothing wobbles when you put the balance board on top. A pleasant side effect of the base: by the padding on the feet little uneven ground as they are in my apartment be compensated.
The only problem I see is with this foundation that I have my doubts whether this will really function unscrew irish well. That's what I though for the foreseeable future not before, but because the plastic is very soft just the screw I have my doubts.
Nevertheless, there is no star for deduction, because the base not to be intended for any unscrewing.
All in all, a strong buy recommendation for anyone looking for a stable, non-slip and very easy held substructure for the Balance Board.
