Frequently asked questions
What loft is best for a side sleeper?
Side sleepers typically need a high loft (5-7 inches) to fill the gap between the head and mattress. A pillow that is too low can cause neck strain, while too high can misalign the spine. Look for adjustable pillows to find your perfect loft.
Are down pillows good for side sleepers?
Yes, down pillows can be excellent for side sleepers if they have enough loft and firmness. However, pure down may compress over time, so look for pillows with high fill power or hybrid constructions that offer better support and durability.
How do I choose a down pillow for side sleeping?
Look for a pillow with at least 600 fill power down or a down alternative blend. Consider adjustable fill, supportive materials like shredded memory foam, and certifications like OEKO-TEX or Responsible Down Standard. A minimum 30-night trial is also recommended.
What is the best fill for a side sleeper pillow?
The best fill balances support and plushness. Down provides softness but needs high fill power (700+) for support. Down alternative, latex, or shredded memory foam offer more precise support. Many side sleepers prefer an adjustable pillow to customize fill.
How often should I replace a down pillow?
Most down pillows last 2-3 years, but high-quality ones with proper care can last 5 years. Look for signs of flattening, lumps, or neck pain. If the pillow no longer holds its shape after fluffing, it's time to replace it.
