Review on Caldera Releaf® Neck Rest Large by David Shah

I read that this soft collar can help with sleep apnea. After trying this collar I was very impressed with how it can make such a big difference when it comes to keeping your airway open while you sleep at night. Although this collar was not designed for this purpose, it does the job perfectly. It is convenient and easy to use. I will also use it on my next long flight. I think it's good to keep your head up when trying to nap on an airplane.
