I've had the foam pillows for over two years and was a restless sleeper. I thought it might be the mattress (also T&N) but it wasn't until I switched to these Down Alternative Pillows as a trial that I realized my sleeping problem was the T&N foam pillows being too high. That said, I love these Down Alternative Pillows. At first sight it may seem like they're too high and bouncy, but once you lay your head into them, your head is enveloped by a cloud. It's great for back and even side sleeping. It reminds me of the luxury hotel pillows. I love them and am buying another set! Slept really well immediately the first night, and guests who have slept on the pillow also liked it!
