No, the seat options you see in the pictures are really all one seat . I currently would have it set for one, but if I were taking my child's best friend I'd want to make it a two-seater. We would be using them on some dirt roads and trails in forests. Our trailers are more durable for this kind of riding than many others on the market. We recommend using caution and common sense in choosing areas to ride in.
Weight is the major reason.
Some who live an area with salt air or salted roads prefer the 400LX because aluminum wheels are not susceptible to rust. Our trailer wheel attaches with a racing wheelchair style attachment. This makes the trailer narrower - to fit through most standard doors. It also makes the trailer fold smaller. There is Scotchlite 3M reflective material on all sides of the trailer, but we do not endorse, nor recommend night use as a safe practice.
