There are some drawbacks to consider. Although the cushion is generally supportive, its medium firmness may not be suitable for everyone, particularly those who prefer a firmer seat. Also, while it can be used across multiple settings, its size might not fit all chairs perfectly, potentially affecting its effectiveness depending on the user's situation. Furthermore, while the product claims to help with back and coccyx pain, it does not guarantee complete relief for all users.
