I purchased this because I was looking for relief for my sciatica. I'm 53 and beyond childbearing years, but I sure would have liked to have had this through both of my pregnancies! Anyone who is a side sleeper, even if you are not pregnant, don't have back pain or a sciatic pain, I think you would absolutely love this Just for the sheer comfort that helps line up your spine perfectly. I had my son, who is a side sleeper, try mine and he loved it! So now I'm buying one for him. I'll have to have my husband try it out. There could be more purchases in the future. I'll also be recommending this to any of my friends with sciatica. Seems like most people of all ages these days are active in this could be the perfect tool and there arsenal of combating muscle aches. For me I'm gardening, have tons of home projects, ride my horses, ATVs and am in the barnyard moving things around, etc. On our little homestead farm. I have and have been experiencing for the last probably 10 years. People are just more active these days and We're just plain harder on their bodies. I'd say most people are side sleepers and this is the perfect way to keep your back in line with your neck. For me it causes less tossing and turning. The way this pillow is shaped is better than any other pillow like it. The fact that it has a curved area for your knees and then also bends in at your back, is really nice. It makes for the perfect pain-free night's sleep.I'm not taking off a star for this by any means, because this is just too good of a product and doesn't even matter what color you have it in, but the color that I ordered was the gray, but the one that i receive is a light bluish gray which seems to be one that's another option in the list of color options... And ironically is about $10 more expensive. I really don't care what color it is, I went for the one that was on sale and light bluish gray or dark gray makes no difference at all to me.Oh another positive note... it has an easy remove cover with a zipper which makes the cover super simple to pull off and wash. The firmness as a pillow is perfection. Not too soft not too firm. It doesn't feel like the type of material that would compress over time either like many pillows do. I guess time will tell but so far so good.
