Memory foam is worth it in the end.
Review by confirmed purchaser
I bought a memory foam pillow and initially found it quite uncomfortable. The first few nights I did not sleep very well but, after reading other positive reviews, I persevered with it and am now very happy with it. It takes at least a couple of weeks if not longer to break it in. In addition, I've had an inflamed tendon in my shoulder for a couple of years which has never healed properly and ever since using the memory foam pillow there are some days I don't even feel any pain and it now seems to be healing nicely. Definitely recommend the pillows.
