Layla BioCrystal™ Side Sleeper Pillow

Your pillow should fill the gap between your ear and the outside of your shoulder, keeping your nose aligned with the center of your chest and your neck running straight from your spine without dipping or tilting. Start with the BioCrystal™ Side Sleeper Pillow at its full 7" loft, then remove one or both adjustable layers until the height feels right. Broader shoulders usually need more loft, while a softer mattress may require less because your shoulder sinks in and closes some of the gap. If your mattress or sleep position changes, simply add a layer back.

The sweet spot is supportive underneath and softly cushioned at the surface. The BioCrystal™ Side Sleeper Pillow uses responsive foam that gently contours to your head, cradles your ear and cheek, and slowly returns to its shape as you move. This balance helps keep your head and neck comfortably aligned without flattening as the night goes on.

Not always, but the BioCrystal™ Side Sleeper Pillow’s U-shaped cutout gives your shoulder a dedicated place to settle flat on the mattress. With your shoulder no longer pressing against the pillow’s edge, the pillow stays comfortably nestled beneath your neck. Paired with adjustable loft, this design helps keep your head, neck, and spine aligned in whatever position you land. You’ll notice the difference most if you have broad shoulders, a firmer mattress, or a sore shoulder on the side you sleep on.

For side sleepers, the best fill is the one that gives you the right balance of comfort and support. Down has a soft, airy feel, while shredded fill can be shaped and adjusted to your liking. Solid memory foam offers a more structured feel, and layered foam lets you adjust the height while keeping the surface smooth and even. The BioCrystal™ Side Sleeper Pillow uses layered foam, so you can find the loft that feels most natural for your neck and shoulders.
