We have bought synthetic down pillows from Costco. Them seem to work ok. Before this, we have down pillows from Costco. We try to toss them out periodically.
@collage1, after trying out many pillows, I use a foam pillow as well.
We purchased My Pillow from Costco. My husband has the slightly larger pillow while I have the slightly smaller pillow (maybe mine is the ‘regular size’ pillow). We had been using 2 pillows each and realized that it was no longer working for us. Spoke with the My Pillow rep and came home with 2 pillows (total - no more 2 pillows a person for us) and we’ve been very happy with this purchase.
