I am a side sleeper and this provides adequate support!  My neck pain and muscle spams have decreased greatly since getting this pillow 2 months ago!   One problem I have is that if my pillow gets flipped upside down and I don't realize it,  and wake up with a stiff neck.  I wish there was a way to identify the top without inspection each night.  I only gave it 4 stars because I am wondering the longevity of the dense foam- it feels like it isn't as thick as before, but it does still provide enough support at this time.  However, it is worth replacing because of the improvement in my neck!
