My husband and I spent the night at a high-end hotel that had firm memory foam pillows on the bed. I've been searching for some just like them because we had the most comfortable night's sleep in ages. Most pillows I found were not firm enough or if they were firm enough, they didn't come in king size. These are absolutely perfect. Though they are pricey and relatively heavy, they are super comfortable and non-allergenic which is a BIG plus. I would wholeheartedly recommend these pillows.
