- Neutral: There is a notable adjustment period (usually 3–7 days) where the position feels “forced” or unnatural.
- Negative: Common complaints include the pillow shifting during the night, the foam feeling too firm for lightweight individuals, or an initial “off-gassing” smell from new memory foam.

- No Guarantees: While many find relief, it is not a guaranteed fix for chronic sleep issues or structural back problems.
