Transform your GSD into a minivan with the Tern Clubhouse+. Use it with the included seat pad and backrest to create a comfy and protected space for two children. Swap out the seat pad for a 15x23-inch crate, and it becomes a heavy-duty grocery hauler. Mix and match seating configurations as your children grow from toddlers to 10-year-olds, with a recommended height between 43 and 55 inches. It’s more fun than a car seat any day.
