8. FAQ Section

Are ergonomic pillows worth it?

Ergonomic pillows can be a worthwhile investment for those who wake up with neck tension. They are designed to support the physiological structure of the spine, which traditional pillows often fail to do.

Do memory foam pillows really help with sleep comfort?

Memory foam can improve comfort by pressure mapping to the body, but it often retains heat. The Core Products Double Core Select foam cervical pillow uses standard cut foam, which stays cooler and provides more consistent “push-back” support than memory foam.

How long does it take to adjust to a new pillow?

It typically takes between 48 hours and two weeks. Because cervical pillows change the way your muscles are positioned at night, you may experience minor “training” soreness initially.

Are there downsides to cervical pillows?

The main downside is the lack of versatility for stomach sleepers, as the raised lobes can overextend the neck in a prone position. They also require a specific sleeping “pocket” which can feel restrictive.

How often should you replace a pillow?

Most high-quality foam pillows should be replaced every 18 to 36 months, or when the foam loses its resiliency and no longer returns to its original shape.
