Match the Pillow to Your Sleep Position

  • Side sleeper: You need a firm pillow with higher loft (thickness) to fill the gap between your shoulder and head. The pillow should keep your ear, shoulder and hip aligned. A pillow that is too soft or flat causes your head to drop toward the mattress, straining the neck.
  • Back sleeper: Medium loft and medium firmness. The pillow should support the natural curve of your neck without pushing your head too far forward. A firm, high pillow hyperflexes the neck; too flat causes the head to fall back.
  • Stomach sleeper (not recommended): If you sleep on your stomach, use the thinnest and softest pillow possible — or no pillow at all for your head. A thick pillow severely strains the neck. Consider a pillow under your pelvis to reduce lower back strain.
  • Combination sleeper: Medium loft and medium firmness. Choose a responsive fill (latex, down, shredded memory foam) that adjusts quickly as you change position.

Pillow Fill Types

  • Down: Very soft, mouldable, light and breathable. Excellent comfort but low support — best for back sleepers or those who prefer flat pillows. Can cause allergies. Expensive.
  • Down alternative (synthetic): Similar feel to down, hypoallergenic, cheaper, machine washable.
  • Memory foam (solid): Conforms to the shape of your head and neck. Excellent support. Can feel hot. Heavy. Does not adjust when you change position.
  • Shredded memory foam: More adjustable than solid. Can be refilled. Good support with more movement flexibility.
  • Latex: Responsive and supportive, naturally cool, durable, hypoallergenic. The best support fill for most people. More expensive.
  • Polyester fibrefill: Budget-friendly, machine washable, lightweight. Compresses quickly over time — replace every 1–2 years.
  1. 1

    Try before you buy if possible

    Lie in your sleep position at the store for a few minutes. The pillow should feel comfortable immediately — no neck strain, no pressure points. Many online pillow brands now offer trial periods (30–100 nights) with returns if the pillow does not suit.

    Replace pillows regularly

    Polyester pillows: every 1–2 years. Memory foam: every 2–3 years. Down and latex: every 3–5 years with washing. A simple test: fold the pillow in half. A good pillow springs back; a dead pillow stays folded. Pillows also accumulate dust mites and should be washed regularly (check the care label).

Frequently Asked Questions

Most people sleep best with one properly sized pillow rather than stacking multiple. Stacking pillows pushes the head too far forward, straining the neck. The exception: using a second, softer pillow between your knees as a side sleeper significantly reduces hip and lower back strain and is worth trying.
Firmness should match your sleep position. Side sleepers need firm support to prevent the head from sinking too far. Back sleepers need medium firmness. Personal preference also plays a role — within the appropriate firmness range for your position, choose what feels most comfortable. A pillow that feels uncomfortable will disrupt sleep regardless of how medically correct it is.
