An observing chair is a must-have for any astronomer who wants to spend serious time at the eyepiece. The Starbound Observing Chair's steel tubing supports 350 lbs. but is light to carry and folds easily for storage. The cushioned seat moves up and down the frame with one hand in seconds. Just stand up, rock the seat up, raise or lower it, then let it down to rest again on the frame. The seat is fully removable for storage.
