I read the specs and reviews for this pillow and expected a much firmer pillow. This is definitely not a side sleeper pillow compared to others that I've had. It is very soft and after contacting customer service and having them do some research, I found out that this is only a 550 fill power.It certainly isn't worth the extra money considering you can order from Overstock the Overfilled 450 Thread Count Pillow with 600 fill power down pillow for $39.99 or the Siberian 500 Thread Count Down Pillow with 650 fill power for 39.99. If you are looking for a firmer pillow , keep looking ! If you don't mind fluffing or folding it in the middle of the night, you might make this work; however for me, this pillow is a big disappointment.
