Acid reflux is one of the most common digestive issues, affecting about 20% of people in the U.S. While occasional acid reflux is usually not a cause for concern, more frequent episodes can lead to complications. Repeated acid reflux, especially at night, can also take a toll on a person’s sleep.
One strategy to reduce nighttime acid reflux is to change your sleep position. While research indicates that sleeping slightly elevated and on your left side can help, it may be difficult to feel comfortable if you’re not used to sleeping in this position. That’s where the right mattress comes in. We’ll discuss how to improve your sleep while living with acid reflux, including how to choose the best mattress for acid reflux.

Why You Should Trust Us
Our team of experienced sleep testers researched dozens of mattress models to find the best mattresses for acid reflux. We prioritized beds with overall high performance in terms of comfort and durability. Then we looked for mattress models with designs that can make it easier to sleep with acid reflux. This included mattresses compatible with adjustable bed frames to raise the head and mattresses that have the right level of pressure relief and support to facilitate side sleeping, which is the best sleeping position for acid reflux.
How to Sleep With Acid Reflux
Acid reflux can cause a number of uncomfortable symptoms, including heartburn and nausea, that may disturb sleep. However, there are steps people with acid reflux can take to reduce their symptoms and get a better night’s sleep.
When acid reflux occurs chronically or results in damage to the esophagus, it’s referred to as gastroesophageal reflux disease (GERD). Speak with your doctor if you experience frequent acid reflux or suspect that you may have GERD.
Understand Acid Reflux and Sleep
Acid reflux doesn’t always occur at night, but some people find that their symptoms disrupt their sleep. Several factors can influence acid reflux during sleep, including eating habits and sleep position.
Improve Acid Reflux Symptoms During Sleep
If you find yourself waking up with heartburn and other acid reflux symptoms, sleeping on your left side with your shoulders elevated and avoiding meals within two to three hours of going to bed may help reduce symptoms.
Consider Mattress Features to Reduce Acid Reflux
People with acid reflux or GERD should look for a mattress that cushions the hips and shoulders for side sleeping while supporting healthy spinal alignment. Choosing a mattress that’s compatible with an adjustable base can also help alleviate acid reflux symptoms by raising the head and shoulders.
How Does GERD Affect Sleep?
Acid reflux happens when the contents of a person’s stomach leak back into the esophagus, the “food pipe” that runs between the throat and stomach. It occurs when the small muscle that helps close off the entrance to the stomach becomes too relaxed.
Many people experience acid reflux every once in a while after a big meal. However, if the symptoms become chronic or cause esophageal injury, doctors refer to it as gastroesophageal reflux disease, or GERD. Common GERD symptoms include:
- Heartburn
- Sore throat
- Coughing
- Stomach ache
- Nausea
- Vomiting
If left untreated, GERD can lead to health issues, including damage to the esophagus and sleep problems.
- Sleep apnea: People with more severe GERD may be more likely to have obstructive sleep apnea, a sleep-related breathing disorder.
- Insomnia: Research indicates that people with acid reflux or GERD tend to experience trouble sleeping, and sleep disturbances may exacerbate acid reflux symptoms.
- Esophagus and throat damage: Untreated acid reflux can lead to damage and scarring on the lining of the esophagus and inflammation in the throat.
- Dental problems: Chronic GERD can break down the enamel on a person’s teeth, leading to dental issues.
How to Reduce Acid Reflux During Sleep
Acid reflux usually occurs soon after eating a meal. For some people, the symptoms can persist and make it difficult to comfortably fall asleep and stay asleep. However, your sleep position can make a significant difference.
What Is the Best Sleeping Position for Acid Reflux?
Several studies indicate that sleeping on your left side and raising the head of your bed can help alleviate acid reflux at night. The research shows that elevating the head and shoulders and shifting weight to the left side of the body can help reduce the amount of stomach acid that leaks into the esophagus.
What Do Side Sleepers Need to Look For In a Mattress?
Your sleeping position influences what you need from your mattress. If you experience acid reflux but aren’t used to sleeping on your side, there are a few factors to consider when looking for the best mattress for side sleepers.
Sleeping on one side tends to place more pressure on the hips and shoulders than stomach or back sleeping, so side sleepers tend to prefer softer, more contouring mattresses to cushion these areas.
- Choose the right firmness: Firmness describes how hard or soft a bed feels. While side sleepers trend toward the softer end of the spectrum, body weight also plays a role in determining ideal firmness level. We’ve found that heavier individuals typically need firmer models even if they sleep on their side.
- Keep your spine aligned: It’s important to find a bed that balances pressure relief with support. A good mattress supports areas like the midsection that tend to hold the most body weight. This keeps the spine aligned and helps prevent pain in the lower back.
- Relieve your pressure points: Side sleeping concentrates all of a person’s weight onto one side of the body. That’s why it’s important to find a mattress with substantial pressure relief. This prevents painful pressure points from forming around the hips and shoulders.
What Can Back and Stomach Sleepers Do for Acid Reflux?
Research indicates that sleeping on your left side can help reduce acid reflux symptoms when compared to other sleeping positions. That’s easier said than done, though, if you’ve spent your entire life as a back or stomach sleeper.
If you’d like to try side sleeping, a slightly softer mattress with deeper contouring may be beneficial to provide extra cushioning for the hips and shoulders. If you’re used to sleeping on your back or stomach, you can also try experimenting with body pillows to keep you from rolling onto your back or stomach during the night.
For Acid Reflux, Elevate the Head of the Bed
Sleeping with your head and shoulders raised keeps your chest positioned above your stomach and takes advantage of gravity to prevent the contents of your stomach from flowing back into your esophagus. You can achieve this position with an adjustable bed frame that elevates the head of your sleep surface. Alternatively, a wedge pillow can elevate your head and shoulders at an angle.
Adjustable Bed Frames
Adjustable bed frames allow you to easily raise the head of your bed. This is ideal if you frequently experience episodes of acid reflux.
Make sure to choose a mattress that’s flexible enough to work well with an adjustable base. Most foam, latex, and hybrid mattresses are compatible with adjustable bed frames, while traditional innerspring models lack the flexibility needed to bend at an angle.
Acid Reflux Pillows
A less expensive option than an adjustable bed frame is to buy a wedge pillow. A properly placed wedge pillow elevates your head and shoulders as you sleep and can help reduce acid reflux symptoms without the need for a new bed frame. Keep in mind that simply stacking standard pillows may not work since they only raise your head.
Choosing the Right Mattress for Acid Reflux
With so many brands and styles to choose from, finding the right mattress can feel like a daunting task. People experiencing acid reflux should focus on finding a mattress that’s comfortable for side sleeping and is compatible with an adjustable bed frame.
Hybrid
Hybrid mattresses offer an excellent mix of features for sleepers with acid reflux. They’re generally compatible with adjustable bed frames, and many models include thick comfort layers that provide substantial pressure relief for side sleeping.
This style of mattress combines a support core of pocketed metal coils for bounce and support with top layers typically made from foam or latex for cushioning.
Foam
Foam beds are another great option for people experiencing acid reflux. Their flexible foam layers are well suited to an adjustable base, and they tend to provide the best pressure relief to cushion the hips and shoulders.
Foam mattresses are made entirely of foam materials and may include memory foam comfort layers and a polyfoam support core. Foam beds also come in a wide range of price-points for people shopping on a budget.
Latex
Latex mattresses offer a unique feel for side sleepers who prefer moderate contouring with more responsive bounce than foam beds. This style of mattress is quite durable and is generally compatible with adjustable bed frames. While some hybrids feature latex comfort layers, latex beds are made entirely of latex materials.
Airbeds
Airbeds allow you to modify the firmness of your sleep surface to precisely match your comfort preferences. This makes them a great choice for people with acid reflux who aren’t used to sleeping on their side. They also tend to work well with adjustable bed frames.
Airbeds feature a large air chamber support core. You can add or remove air to change the feel of the bed, usually with a remote control or smartphone app.
Innerspring
Innerspring mattresses may not be the best choice for people with acid reflux, as they aren’t always compatible with adjustable bases and often lack cushioning for side sleepers. Traditional innersprings consist of a thick layer of interconnected wire coils, minimal cushioning, and a cover.
More Ways to Reduce Acid Reflux While Sleeping
In addition to optimizing your sleep position and mattress, there are other evidence-based ways to reduce acid reflux while sleeping.
- Identify what foods to avoid with acid reflux: Some foods may be more likely to trigger bouts of acid reflux. Different foods can affect people differently, but you can experiment with eliminating fatty foods, spicy foods, caffeine, chocolate, and carbonated drinks. It’s also a good idea to avoid eating three hours before bedtime.
- Take steps to reduce acid reflux during pregnancy: If you’re pregnant or breastfeeding, medical experts recommend using lifestyle changes to improve acid reflux symptoms. This can include avoiding late night meals and certain foods as well as dressing comfortably in loose-fitting clothing. Pregnancy pillows and wedge pillows can also help you find the most comfortable sleep position and keep your head and shoulders elevated.
- Discuss your symptoms with your doctor: Occasional acid reflux is normal, but if you’re experiencing frequent or serious episodes, discuss your symptoms with your doctor. They can give you an accurate diagnosis and develop a personalized treatment plan. This may include additional lifestyle changes, over-the-counter or prescription medications, or, in rarer cases, corrective surgery.
