Dr. Marink's is a miracle pillow. It took years of looking, trying, accepting, but never truly liking the pillow I would sleep on every night. I bought flat ones, thick ones, soft ones, and firm ones. I bought special branded pillows for those who suffer with neck and back problems that promised to take away the pain and guarantee the perfect night’s sleep. Never worked. I have collected pillows of disappointment. But I accepted that i would just get used to it. Since I’m a side sleeper, I needed something firm, not too low, not too high, that would help me get a good night’s rest. I found Dr. Marink's pillow to try, with varying sized inserts, that would allow me to adjust the height; after trying it out for a week or so, I was amazed at how great I slept and how my pain went away. It’s been over a year that I’ve been using Dr. Marink’s side sleeper pillow and I love it. I haven’t bought another pillow since. This pillow is still as comfortable as when I first bought it, and has not lost its shape or firmness. The quality is exceptional. Highly recommend it.
