The dice are a little larger than expected, assemble easily and should a reasonable! Maintain weight. I think a normal adult can sit well built. 300Kilo is as exaggerated as - only for children. Have the Sitzwürfel for 5, 99 can grab the offer and am therefore fully satisfied. Easy to assemble, they are also well stowed in the folded state. Thought at first the dice are in white color somewhat dirty ... the light one sees that it comes to an EHR wollweiss- beige. Something bad would probably order the next time colorful.
