Layla BioCrystal Side Sleeper Pillow review

Layla built the BioCrystal Side Sleeper Pillow around a sculpted U-shaped cutout and a tall profile. It arrives at a 7 inch loft, which Layla calls ideal for most side sleepers, and you unzip the cover to remove one foam layer for about 6 inches or two for about 5 inches. That makes it a good match for people with broad shoulders or a firm mattress, who need more height than the 6 inch maximum on the Eli & Elm. Because it uses layered foam rather than shredded fill, the surface stays smooth and the height changes in clear steps. Layla infuses the foam with a blend of 16 milled crystals it calls BioCrystal and says the surface stays cool. The pillow is OEKO-TEX Standard 100 certified as a complete product. It cost $149 when we checked, against $189 regular. The 30-night trial is short, and Layla asks buyers to sleep on it for at least two weeks before returning it.
