A big part of that is the construction. It has a hypoallergenic latex core that’s wrapped in the same kind of Purple Hex Grid design that made the brand’s mattresses so famous—the grid creates 1,500 air zones, making it incredibly breathable, while evenly cushioning your head. It’s a dream for hot sleepers (no more 3 a.m. sweat puddles!), and its gentle support means it cradles your head and neck, but you don’t feel molded in place—or worse, swallowed up by it. While other pillows started to create an indentation after a few weeks, this one has retained its shape perfectly.
Purple says it went through 50 prototypes to land on a headrest that’s roughly the same weight as your standard pillow, while being supportive and cooling, and it shows. The Harmony is available in three heights (low, medium and tall, depending on your preferred sleeping position) and two sizes* (standard and king), making it customizable to your needs. Oh, and if you don’t like it, you have 30 days to return it, making the splurge a bit easier to justify (especially if it’s on your wedding registry).
*There's also a smaller travel size, but I'll be honest: I have one and don't love it nearly as much. It's the right size to wedge between your head and a window on planes, but I don't find it nearly as comfortable. When scaled down, the Harmony seems much firmer, to the point that I took the Hex Grid layer off just to make it soft enough to rest my head on. It's worth paying more for a standard-size pillow.
