Frequently asked questions
What loft is best for side sleepers?
Side sleepers typically need a high loft (4-6 inches) to fill the gap between the shoulder and ear. This keeps the spine aligned. Adjustable pillows are ideal for fine-tuning the height.
Should side sleepers use a firm or soft pillow?
Side sleepers usually benefit from a medium-firm to firm pillow. Too soft allows the head to sink, misaligning the spine. Firmness should complement the loft to support the neck.
Are memory foam pillows good for side sleepers?
Yes, memory foam conforms to the head and neck, providing good pressure relief. However, some may retain heat; look for cooling features or gel infusions.
How often should side sleepers replace their pillow?
Pillows should be replaced every 1-2 years. Signs of wear include lumps, loss of loft, or waking up with neck pain. Owner reports suggest that quality pillows last longer.
What certifications should I look for in a side sleeper pillow?
Look for CertiPUR-US and OEKO-TEX certifications. CertiPUR-US ensures foam is free from harmful chemicals, while OEKO-TEX certifies the cover is safe. These are common in top-rated pillows.
