I haven't been very pleased with this pillow so far. I am 21 weeks pregnant and have a lot of trouble sleeping at night because I usually sleep on my stomach. Now I am trying to train myself to sleep on my side and always find myself on my back when I wake up throughout the night. I thought this pillow would help to keep me on my side but it hasn't at all. There is so much room between the 2 pillows, that it doesn't keep me wedged between them. I still end up on my back all the time. Not to mention that the pillows are so fluffy that it makes it difficult to get out of bed, which I do several times a night for bathroom trips. Another thing I didn't like was that fact that I can't put a pillow case on it unless I custom make one to fit and the material quality isn't good so I worry it will fall apart. I stopped using the pillow because it just wasn't right for me. I plan on picking it up again a little later into my pregnancy to see if it works better for me then, but for now I am giving this pillow a thumbs down.
