No matter how you sleep — on your back, stomach, side — this allergen-free soft gel pillow conforms to the shape of your head and provides long-lasting comfort. The ultra-breathable sateen cotton cover stays cool throughout the night and is resistant to stains, mold, and mildew. The pillows themselves are machine-washable, though they claim to be immune to stains or fading, as a plus. A perfect option for people who have asthma and other respiratory issues, these pillows are an Amazon's Choice product with a near-perfect rating.

Positive Amazon review: “I have owned these pillows for 6 months now and love them! They keep their shape. I use both of them. They are like hotel quality at a fraction of the price of other pillows that I have owned.”

Sleeping on your back is considered one of the healthiest positions for your spine and neck, but it isn't always easy to stay in one place throughout the night. This pillow is unique in that it's designed with a supportive, trapezoid-shaped center to cradle the head and neck and side lobes to keep you from tossing and turning. Unlike a lot of other pillows, this one gives you the option of choosing among five sizes that include firm, gentle, and petite. It also comes in white or blue.

Positive Amazon review: "I love this pillow. I have used it in the past and it is such a relief for my neck and my shoulders. I will say that it does take a bit of getting used to, but I sleep so much better with it. The pillow helps me to sleep mostly on my back, which is better for my shoulders. But it also supports my head and neck nicely when I sleep on my side.”

This curved pillow may be a tad pricy, but it conforms to the shape of your head and neck, offering superior support. Removable latex and polyester filling lets you adjust the pillow's firmness so that it's right for your body. The cover is made from a super-soft blend of organic cotton, spandex, and polyester and can be cleaned in a washing machine (just remove the fill first!). The pillow is resistant to microbes, dust mites, and mildew, which means it shouldn't bother anyone with allergies. Users report that this holy grail product is very much worth the price.

Positive Amazon review: “I've had this pillow for over a year now and I still love it! Almost immediately, the constant neck pain I woke up with was gone. I don't know how it works, but it does! I recommended to my cousin and her husband and they both love it too!”

One of the biggest complaints about many pillows is that they flatten easily — and once that happens, there's no turning back. Not so with this bamboo shredded memory foam pillow, which springs right back to life after you put pressure on it. Reviewers (more than 4,000 of them) love how this hypoallergenic material is resistant to allergens and dust mites and won't irritate allergies. Whether you sleep on your back, stomach, or side, this pillow provides neck and head support to prevent aches and pains. And sweaty sleepers will also find a bit of extra relief: The cover is made with a breathable fabric called Kool-Flow, which stays cool throughout the night.

Positive Amazon review: "Quite cool and pleasant to sleep on in warmer weather. Does not make you sweat like a traditional shredded foam pillow does; this thing is really quite an improvement over my normal solid memory foam pillow. The zippered bamboo outer case is soft, breathes well, and is super solid. I can't see ever having a problem with foam bits leaking out (there is a second inner case with its own zipper). All said, we bought a second one right away, and I'd recommend them to anyone. Great product!"

Fans of traditional soft and fluffy pillows say this is one of the softest white goose down options you can find. It has 550-fill power (the higher the fill, the loftier it is, with 800 as the typical maximum amount) and a 100% cotton shell. Reviewers say the fill quality is excellent for back and side sleepers, but may be too much for stomach sleepers — something to note. It's great if you don't want a pillow that's too hard, and one spin in the dryer can help fluff it up if it gets too flat. Choose from an assortment of sizes in sets of one or two.

Positive Amazon review: "I have been so happy with this pillow that I bought a second one so as to be able to rotate them when changing the bedding [...] A bit pricey, but if you prefer down to synthetic pillows, you will love it [...] In the morning grab it by the corners and give it a shake, and it plumps right back up, ready for another blissful night of comfy sleep.”

Finding relief from snoring, acid reflux, and allergies at night is possible — and it has a lot to do with how you sleep. This memory foam wedge pillow props you up in such a way that it promotes better circulation and airflow. It has a two-layer design: comfortable memory foam is placed on top of a base foam to provide more support. You can use it for your head or under your legs and knees to prevent back pain while sleeping. Every order includes one white machine-washable cover, with the option to purchase more, if you wish.

Positive Amazon review: "This pillow solved both problems of acid reflux AND snoring. It's comfortable and not hard like I expected. I use it every night and look forward to being perfectly positioned for good sleep without disruptive snoring or acid reflux."

If you're waking up to a stiff neck more times than you'd like to admit, the culprit could be your pillow — and this neck pillow may just be your solution. Made from memory foam with a removable, machine-washable bamboo cover, this pillow is double contoured to support the specific areas of your neck and head where you need it most. It comes in medium, thick, or thin profile options, and the foam the brand uses is free from chemicals, like lead and mercury, that have been known to be found in some lesser-quality foam pillows.

Positive Amazon review: "My PT Therapist recommended this pillow and I was skeptical because of the price and I already had many contour pillows, but I decided to try it. I have chronic neck and shoulder pain and I can't believe it, but within a few nights with this pillow I had no pain at all. I have been sleeping better, with no pain and waking feeling refreshed! I just bought three pillows for the rest of my family so they can sleep better too.”

This pillow releases copper ions as you sleep, which is believed to have skincare benefits — one being that it may not cause any creases on your face, which can reduce the appearance of lines over time. It's infused with antimicrobial fiber fill and is described by reviewers as both "supportive and comfortable." Others note that their skin never gets hot at night when sleeping on this pillow.

Positive Amazon review: "I don't know much about copper being rejuvenating for skin, but this pillow is great! The pillow is very comfortable, made my sore neck feel better. The case is very soft and luxurious. It does not make creases on my face, which is a plus! Love this pillow and would highly recommend it."

When it comes to sleeping, we all have different needs — they can even change from month to month. And this memory foam pillow, made with 40% rayon derived from hypoallergenic bamboo, gives you the option of adjusting its foam interior to suit the level of support you currently desire. It comes in queen and king sizes and has more than 49,000 reviews, with one fan calling it an "adjustable cloud" that's soft and conforming to the body.

Positive Amazon review: "I've never had a pillow that I've particularly loved until this one. I looked through a ton of reviews and articles ranking the "best" pillow before I landed on Coop. It has now been over a year and a half, and this pillow is still going strong! We got another one for my partner who has been using his Coop for just as long, and he also loves it! I get very particular about mine, because it has the perfect amount of "oomph" in it for me. I absolutely love this pillow and can't imagine ever having another one again. I just bought a third one for our new guest bed.”
