I have had a therapeutica pillow for years and I love it. The foam is disintegrating so I ordered another one. My mistake is that I ordered a petite thinking that the only difference is the hight of the sides but what I have found out is that the center piece is also smaller. I am a side sleeper but I prefer to have my head in the center rather than up onto the sides. I am still using my old pillow as it is so comfortable even if it is crumbling .
