This is an interesting eye mask. It comes with a back pillow, which can tie to the chair head rest. The mask then attach to the back pillow. The idea is good.I think the biggest issue with this eye mask/pillow is fixing the back pillow on the headrest. It comes with 2 straps. I tried it on my high back chair. I have to cross tie it over the headrest. Good that it is working. I believe it will work on airplane seat too.So I follow the instruction and attach the eye mask on. It is firm. My head can now stay on an upright position. The cushion on both the back support and eye mask are thick and soft. I don't feel I am tied or fixed to the chair. Instead, I feel comfortable, resting on the chair.Overall, I think this eye mask will work. I would give it 4.5 stars.
