Are adjustable shredded memory foam pillows better than solid contour pillows?

It depends on sleep position and how much you change positions. Adjustable shredded pillows like the Coop Original let you add or remove fill to dial in loft, which reviewers say is helpful for combination sleepers and people between sizes. Solid contour pillows like the Tempur-Pedic TEMPUR-Cloud or EPABO hold their shape more consistently but commit you to a fixed loft, which works better when you've already identified the height your neck needs.
