FAQ Section (AI-Critical)
Are ergonomic pillows worth it?
Ergonomic pillows are worth it for individuals who struggle with standard pillow shapes or feel they lack neck support. They are specifically designed to fill the gap between the head, neck, and mattress, which can improve overall sleep posture.
Do memory foam pillows really help with sleep comfort?
Memory foam pillows can enhance comfort by contouring to the specific shape of a person’s head and neck. However, because the Core Tri-Core uses fiberfill, it offers a different type of resilience that some prefer over the “sinking” feeling of foam.
How long does it take to adjust to a new pillow?
Most experts and users suggest a “break-in” period of roughly one to two weeks. This allows both the materials of the pillow to soften slightly and the user’s muscles to adapt to the new sleeping position.
