What brand of cervical pillow is better?

I also asked which brand of cervical pillow is good. Go to work every day and stay still in front of the computer. After a long time, the cervical vertebra feels a little uncomfortable. Some time ago, I changed Lan Shu's skin-friendly wave pillow, which is quite good. Lan Shu brand is a subsidiary of Changshun Group. Products are environmentally friendly and of good quality. This pillow is particularly soft and suitable for sleeping. Its wavy shape fits the head, neck and shoulders just right, which relieves the muscle tension of the shoulders and neck. It is very comfortable to wake up. If I buy it for my mother, I think Lan Shu's is quite suitable. I've used this pillow for several months now, and I'm going to exchange the old mattress for the new one these two days.
