The piilows are GREAT. Very little loss during use so far, and comfort level is a 9 out of 10. Why a 9? Because they take a while to "break in" to the way I sleep, and I admit to having a few stiff necks when first using these, BUT after 1 month they were comfort incorporated. I have allergies, and some pillows make me sneez. These did NOT. Highly reccommend and 4 at that price is a steal.
