After searching for literally MONTHS and after only one night of sleeping on my new Natural Nights 750 Med./Std., I have FINALLY found my perfect pillow!!! I have to begin by saying that when I first opened the box, I was terribly disappointed because I thought there was no way in H - E - double LL that this pillow would be "the one". It was far too light and seemed to be made of nothing but air and I needed something soft, yet supportive. Feeling totally worn out by this entire pillow purchasing process, I was contemplating giving up my search for good and just sending the derned pillow back without even trying it. But then I realized that I might never get another chance to sleep on a $300 pillow! So.... As soon as I laid my head down - WOW - like sleeping on the wing of an angel! Not only is this pillow soft, but it's got substance as well - something that I hadn't expected given how light weight it is - and it cradled my neck beautifully all night. I absolutely love this pillow! I am oh so happy to have finally found the best one for me - 62 y/o female, 5'4", healthy weight, side/back sleeper, med/soft mattress. I am thankful to David, who, with his pillow knowledgable and great guidance, lead me to "the one". I highly recommend giving him a call if you have any doubts about which pillow to try first. They're not inexpensive but the quality and service are there. Thankfully yours
