I gave these pillow a try after reading reviews on O. We have a Sleep Number bed and we usually replace our pillows with Sleep Number pillows, which, to us, are the best around. I ordered 4 of the Rest Remedy pillows for the price of one Sleep Number pillow, not expecting the quality of pillow that I received. The pillows are extremely supportive, whether sleeping on my sides or my back, and my husband finds that he no longer requires 2 pillows for sleeping. A very good pillow for an excellent price.
