The Entourage second seat is now rated from 6 months up to 40 pounds. After additional testing we were able to increase the weight capacity of the second seat from 35 pounds to 40 pounds (it turns out, we were better than we thought!). We are continuing to evaluate if we can increase the weight capacity even more. No matter when you purchased your Entourage second seat, it is now rated up to 40 pounds. Yay!
