Frequently asked questions
What firmness is best for back sleepers?
Back sleepers generally need a medium to medium-firm pillow to keep the head aligned with the spine. A pillow that is too high or too soft can cause neck strain. The Purple Harmony (medium-firm) and Purple Original (medium) are top choices.
How do I choose the right loft for back sleeping?
Back sleepers should aim for a loft of 4 to 5 inches, depending on body size. Smaller frames need lower loft, larger frames higher. Purple offers adjustable pillows like the TwinCloud and Freeform to customize loft.
Are Purple pillows certified safe?
Yes, Purple pillows are CertiPUR-US certified for foam content and many are OEKO-TEX Standard 100 certified, meaning they are tested for harmful substances. The covers are also often hypoallergenic.
Do Purple pillows sleep cool?
Yes, the GelFlex Grid technology is designed for airflow and heat dissipation. The Harmony and Freeform models are particularly noted for cooling. Owners consistently report that Purple pillows stay cool through the night.
Can I return a Purple pillow if I don't like it?
All Purple pillows come with a 100-night trial period. If you're not satisfied, you can return it for a full refund. This allows back sleepers to test the pillow risk-free.
