The only beef I have with the InStep double seat trailers is that the seat is one wide seat with two harnesses. Our older Schwinn trailer had two separate "buckets" in the seat. The difference is that with two kids, they tend to start sliding to the middle while riding in the InStep trailer and on longer rides this usually caused discomfort which then leads to grumpy kids. Other than that, the construction of the InStep has kept it going in our family for many years.
