8. FAQ Section
Are ergonomic pillows worth it?
Ergonomic pillows are generally worth the investment if you suffer from poor sleep posture or wake up with routine stiffness. They are designed to follow the body’s natural curves, which can lead to more restful sleep compared to flat, non-supportive pillows.
Do memory foam pillows really help with sleep comfort?

How long does it take to adjust to a new pillow?
Most people require a transition period of 7 to 14 days when switching to a new pillow type. This is especially true for body pillows, as your body must adapt to a new physical alignment and the presence of a larger object in the bed.
Are there downsides to cervical pillows?
Cervical and ergonomic pillows can sometimes be too firm or have a specific shape that limits movement. If a pillow is not the correct height (loft) for your frame, it may inadvertently cause more strain, making it important to choose a model that matches your shoulder width.
How often should you replace a pillow?
Most experts recommend replacing high-quality pillows every 1 to 2 years. While the Sleep Number cooling body pillow is durable, the internal fibers eventually lose their resilience, and the accumulation of allergens may necessitate a replacement for hygiene and support.
