I held off making a review on these pillows for several months to see how they held up. I am a side sleeper and have been known to destroy pillows in very short order. These pillows have held up surprisingly well. After five months, they still are holding their shape and offer superior support. Since I have been using them, I have not had any issues with back , shoulder or neck pain that I suffered with while using my old pillows. I highly recommend these pillows!
