Sunset views at Arches National Park

I've got a trip to Arches coming up, and would really like to enjoy a couple sunsets (with camera) in the park. Due to a back injury, I can't stand or walk for extended periods of time, so I am looking at short trails with views, like Balanced Rock, Double Arch, and Double Arch. I know parking is going to be tricky, so I plan to arrive early, but what I really want to know is whether any of these locations (or other locations people can recommend) would be conducive to me bring a folding camp chair to sit since the hike, plus standing for a while will be painful.
