To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Pillow takes up hardly any space! Make sure you test out the inflation pressure, found that I needed to let out some air, still very comfy even half inflated, and I needed that to get comfortable. If you get the Sea to Summit sleeping pads (2019 version at least) you will get these pillow lock stickers that will basically velcro the pillow in place, works great! Highly recommended.
