Hello, Sally.
Thank you for taking the time to write a review and for sharing your experience with your Coleman® Elite WeatherMaster 6-Person 11 ft. x 9 ft. Lighted Tent with Screen Room. We're sorry to hear that your tent's seams aren't sealed and that it's incredibly light for such a large tent, causing it to leak. We appreciate your time and effort for bringing this to our attention and we apologize if our product did not exceed your expectations. This is certainly not the experience we want you to have. We want to make sure that we provide quality products that have great value, stylish and will suit your needs. As we are looking for ways to better our product and service, we always ensure that consumers' feedback and concerns are shared with the concerned department. Please let us know if you need further assistance. Have a wonderful day.
