some of the above estimations are ballpark. i just wanted to add that taking into consideration that this product is not large in size and it is made of wood composite i wouldn't push the amount of weight on those legs i use it as an ottoman. More information like this can be found on the wood-plastic composite wiki this was taken directly from the page
" This means that they have a lower strength and stiffness than wood, and they experience time and temperature-dependent behavior. The wood particles are susceptible to fungal attack, though not as much so as solid wood, and the polymer component is vulnerable to UV degradation. It is possible that the strength and stiffness may be reduced by moisture absorption and freeze-thaw cycling, though testing is still being conducted in this area. Some WPC formulations are also sensitive to staining from a variety of agents."
