What is the opinion of Reddit about the
Core Products Double Core Select Foam Cervical Support Pillow, 4 Interchangeable Orthopedic Support Rolls & Pillowcase Included?

I realized that I need really good cervical spine support (i.e under the neck support) when sleeping so I started keeping an eye out for relevant pillows. Getting something like this completely changed things and now I sleep soo much better.

This is the head pillow I bought.

The knee one I bought was cushion lab but it hasn’t come yet.
