Preference for pillows and perception of pillow is a supremely subjective thing. So while reading through reviews about pillows may be helpful, it will ultimately come down to your personal experience with it. What I love, you may despise. What you love, I may detest. Exact same pillow but very different opinions. Doesn't mean someone is right, and someone is wrong; just depends on whether that particular item is right for someone's needs and preferences.I'm 5 starring this because it is my second set. I know what to expect and I like it. If I were nitpicking, I may go with 4 or 4.5.So here are my stats:--I am a side sleeper. I sleep with one arm under my head, so pillow is always between my angled up, folded arm and my large head.--I hate hot pillows. I hate hot sleeping. I want to be cool. I will use cooling pillow cases (helps not trap heat).-- I like medium firm pillows with some "give". I prefer to have one pillow of semi firmness that I use to support some of my head and a little bit of shoulder, then have another pillow that is more malleable to be under my face and rest of side of head. Kind of scrunched.--my shoulder tends to ache at some point, and my arm usually falls alseep.OK, so HOW does THIS pillow fit in?I use it as my top pillow. It DOES NOT TRAP HEAT, and it has a weird cloud like feel that always ALWAYS makes me go "ahhhhh", even as I flip over in the night. There is a weird level of comfort that this pillow provides. What is this sorcery?Downside-ish is that is IS soft. Lofty, but my head drops down into it a bit and the sides go up, especially if my arm isnt underneath it. But when my arm is underneath it.. mmm perfection. It is COMFORTABLE (to me). I dont use in while on my back reading or watching tv, or playing solitaire on my phone before sleep. I need a firmer pillow. But when I roll over to get into sleep position, it is like this gorgeous level of comfort. It just feels so nice.My shoulder doesnt ache as much, and my arm doesnt fall asleep as often.That all being said, this is not a FOREVER pillow. I do have to swap out after a period of time. It will eventually lose that cloud feel and just become a regular pillow. But its fine for several months easily. This is my second set, all mine. With the first set, I kept one and my husband used one. He may still be using his. I bought this current set recently on a whim. I forgot how blissful the pillow can be (I am not sure what happened to my pillow, perhaps my dog stole it), and am very happy to have a fresh one to use right now, and a spare for another point in time.I at least know that I LIKE this pillow, and even if I am buying it every year or so, it is better than trying out all sorts of other pillows and hating them.This may be something you love, or it may be the worst pillow ever.But it has good stitching, cleans up easily, does not trap heat like some pillows. So I think quality is there. As for rest (comfort, support) that will be up to your perception and your body and sleep style.
