This muscle is meant to expand to allow food to enter the stomach and then retract to seal off the stomach from the esophagus while the food is digesting.People experiencing acid reflux have a weakened esophageal sphincter, which means that it doesn’t retract properly and allows the stomach acid to flow back up into the esophagus. Unlike the stomach, which has a special lining to protect the organ from the negative effects of the stomach acid, the esophagus doesn’t and can wear down over time.Currently the only treatment for acid reflux is an over-the-counter medication. Additional symptoms and preventative measures are treated by avoiding certain foods (tomatoes, caffeine, mint, chocolate, citrus, vinegar, garlic, and onions) and making lifestyle changes, including adjusting sleeping positions.What Acid Reflux Patients Should Look For in a MattressBefore choosing your best mattress, look first at mattress types, your sleeping position, what type of sleep trial, warranty, and return policy are available, and if you want to invest in an adjustable bed or use a wedge pillow for elevation.Mattress TypeEach mattress type offers its own set of benefits and drawbacks. For example, memory foam offers great pressure relief but comes with a higher risk of overheating. Know the differences between each type of mattress and decide which one is right for you.Memory Foam MattressesMemory foam is one of the most popular mattress types on the market today. Known for its ability to relieve pressure points by conforming to the body, memory foam isolates motion and sleeps silent. Memory foam mattresses do run the risk of retaining heat, but adding cooling features like plant-based foam and gel infusions allow for better airflow and absorb body heat for temperature regulation.A memory foam mattress contains a comfort layer of memory foam and a support layer of high-density foam.Innerspring MattressesChances are, you grew up sleeping on an innerspring mattress. Innerspring mattresses have been the traditional go-to mattress for decades. Innersprings have a responsive bounce and excellent cooling thanks to the open structure of coils.An innerspring mattress contains a thin comfort layer of foam or fiber, usually acting as a pillow top and a support layer of steel coils.Latex MattressesLatex comes in two forms— synthetic and natural. Synthetic latex is created through a chemical process, while natural latex is extracted from rubber trees then whipped into a foam. Latex is similar to memory foam, except it sleeps cooler and is more responsive. Latex is also more expensive because of its natural material.A latex mattress contains a comfort layer of latex and a support layer of either high-density foam or latex.Hybrid MattressesA hybrid mattress is a combination of the best of both worlds— pressure-relieving memory foam and responsive innerspring coils. A true hybrid must contain a 2-inch comfort layer and a coiled support layer. While hybrid offer the benefits of both memory foam and innersprings, they also come with drawbacks, like less pressure relief and overheating.A hybrid mattress contains a comfort layer of memory foam or latex and a support layer of pocketed steel coils.Sleeping PositionSleeping position has a major impact on the mattress you choose— each sleep position requires a specific level of comfort and firmness to keep the spine in neutral alignment. Your preferred sleep position may also increase or reduce acid reflux.Side SleepingSide sleeping is one of the most common and most healthy sleep positions, improving breathing. For those who suffer from acid reflux, sleeping on the side in particular prevents acids from traveling to the esophagus. The best mattress for side sleepers is usually medium in firmness, as side sleepers need cushion to prevent pressure points but support to maintain healthy spinal alignment.Back SleepingBack sleeping is another healthy sleep position, but not for those with acid reflux. Lying flat on the back can exacerbate heartburn and indigestion, worsening acid reflux. Back sleeping can also cause development of sleep apnea from the collapse of soft tissue at the back of the throat from gravity.Stomach SleepingStomach sleeping is the least common sleep position and the least healthy. Stomach sleepers have a greater risk of neck strain and lower back pain because of the amount of pressure placed on the spine. For those with acid reflux, sleeping on the stomach can worsen symptoms because of the pressure placed on the stomach, forcing acid into the esophagus.Sleep Trials, Warranties, and Return PoliciesSleep trials, warranties, and return policies act as assurances to the customer. Always read the fine print of each and know the details before committing to a potential buy.Sleep TrialA sleep trial allows the customer to try a new mattress within the comfort of their own home. It takes about 30 days for the body to adjust to a new mattress, so most sleep trials last between 90 to 120 nights. If the customer isn’t happy with the mattress, they can contact the company and arrange to have it donated or recycled before issuing a full refund.WarrantyA warranty protects the mattress from manufacturing flaws and defects, and sagging greater than 1 inch, depending on the brand. Most mattresses come with a standard 10-year warranty. Be wary of mattresses with no warranty— it could be a warning sign of a cheaply-made product.Return PolicyIf a new mattress doesn’t come with a sleep trial, check out the return policy. Most return policies last 30 days— the same time it takes the body to adjust to a new mattress. If the customer isn’t satisfied with the mattress, they can return it for a full refund.Adjustable BaseAn adjustable base might be the solution for you if you suffer from acid reflux or GERD. Mattresses with an adjustable base have mechanisms with multiple hinges to allow the user to mechanically elevate the head or foot of the bed based on their personal preference. Elevating your head during sleep can reduce the symptoms of acid reflux.If an adjustable bed base isn’t an option for you, consider trying a wedge pillow. These triangular-shaped pillows are often made of soft foam and help keep the upper body elevated. As an added bonus, these pillows are easier to transport and often cheaper than an adjustable base.Other Things to ConsiderDoes elevation help acid reflux?Many people with acid reflux or GERD find that keeping the top part of the body elevated helps reduce acid reflux during sleep. When adjusting your sleep position in this way, it allows gravity to work in your favor, keeping the acidic stomach contents from leaking into the esophagus, which is the cause of the burning pain of heartburn and indigestion. It’s important to note that while this method works for many people, it might not be the right option for everyone. Consult with your doctor for advice.How much should I elevate my bed for acid reflux?Many people suggest elevating the head of your bed at least 30 degrees, or 4-6 inches. However, depending on the severity of an individual’s acid reflux you may need to increase or decrease that level for personal comfort. If you’re unsure of the ideal elevation for your needs, consider consulting with your doctor or a sleep expert.How can I improve my mattress to ease acid reflux?If you don’t have an adjustable bed, you can use a wedge pillow to elevate your head and keep acid reflux at bay. Wedge pillows take the place of your normal pillow and keep you propped up while you sleep. These are an inexpensive way to modify your current mattress to better ease acid reflux discomfort.Does GERD ever go away?It can! Not everybody’s GERD will entirely go away, but if you have mild acid reflux, it can be treated with medication and lifestyle changes. Your doctor is the best person to speak with about treating your GERD, so it’s best to talk with them and hear their suggestions. Plus, your doctor will be able to tell you if these suggested treatments can completely eliminate GERD.What type of mattress is best for GERD?The materials inside of a mattress can’t necessarily help GERD, so really, the best mattresses for acid reflux are ones that pair well with an adjustable bed. Memory foam, latex foam, and hybrid mattresses all work well with adjustable bed frames. These beds are flexible enough to adapt with the base’s changing movements.ConclusionIf you’re facing struggles with acid reflux or GERD, it’s important to know the sleep technology available to help you rest comfortably. For some, that may mean upgrading your mattress to one that’s better suited for side sleepers or back sleepers. For others, it may require investing in an adjustable base bed or a wedge pillow to help maintain an elevated state during sleep.No matter what option you choose, it’s important to consult with your doctor to make sure you’re making the safest and healthiest choices, especially if you have acid reflux. If you do invest in a new mattress, be sure to take advantage of the trial period to allow your body to adjust to the new bed. Better sleep with acid reflux is possible.This article is for informational purposes and should not replace advice from your doctor or other medical professional.
