The picture provided is not of the actual chair. The actual chair does not have the  support piece under each arm as shown thereby given the chair a less sturdy & impressive look. The slats on the backrest are further apart than picture indicates.
 I doubt this chair would survive repeated use from a 250 lb man, especially as the footrest is fairly flimsy. 
On the positive side, I applied teak oil which really brought out the best in the wood.
