How long does it take to adjust to a new pillow or mattress?
Most experts and manufacturers suggest a “break-in” period of at least 30 nights. Your muscles and ligaments require time to adjust to a new alignment, especially if you have been sleeping on an unsupportive surface for a long time.
Are there downsides to cervical or zoned pillows/mattresses?
The primary downside is lack of versatility. A product designed perfectly for a side sleeper’s shoulder may be uncomfortable if that person tries to sleep on their stomach. Additionally, specialized shapes often require specific, proprietary pillowcases or sheets.
