Eight hundred pounds on a 24 lb bench is the acacia doing the work - a hardwood dense enough that the frame needs no metal reinforcement. The seat measures 40 x 17 in for two people, set 17.5 in off the ground with a 13.5 in backrest and armrests at 29.5 in. It stands 47 x 20 x 31 in overall. The wood is left natural so the grain shows; an oil coat once a season keeps it from graying, and it is better kept out of prolonged rain. Assembly is required with instructions supplied.
