What is the maximum weight limit for the Graco Duoglider stroller?

The stroller should not be used with two children weighing a total of more than 80 lbs. (36.2 kg). The weight in either individual seat should not exceed 40 lbs. (18.1 kg), and the height in either seat should not exceed 43 in. (109 cm). Exceeding these limits will cause excessive wear and stress on the stroller. (Page 4)
