1. Amerisleep AS3

as3 best mattress for back painThe Amerisleep AS3 is our recommended mattress for acid reflux relief because it’s built to promote healthy side sleeping, which is ideal for reducing the symptoms of this uncomfortable disorder. Amerisleep’s AS3 is medium in firmness and offers a good balance of comfort and support, so it’s never too soft or too firm.

All in all, Amerisleep’s AS3 is 12 inches thick and contains three layers: 3 inches of Bio-Pur®, 2 inches of Affinity with HIVE®, and 7 inches of Bio-Core®. Plus, it’s compatible with an adjustable base— great sleep accessories for elevating the head and preventing digestive discomfort.

The first layer of the AS3 is 3 inches of pressure-relieving Bio-Pur®, a plant-based memory foam. Amerisleep designs their foam with an advanced open-cell structure to improve breathability and responsiveness, so you’ll never feel like you’re sleeping on a heat trap. This comfort layer is thick enough to cushion the shoulders and hips as you sleep on your side, but not so thick that it causes you to sink uncomfortably far in the mattress.

Below the layer of memory foam is the Affinity with HIVE® layer to offer zoned support. HIVE® is clinically proven to reduce pressure points by 49%, which is ideal for those who are already side sleepers as well as those transitioning to side sleeping. HIVE® is firmer under your midsection, head, and feet to promote neutral alignment and softer under your shoulders and hips to allow for deep compression and pain relief under those joints.

The last layer of the AS3 is 7 inches of Bio-Core®, a sturdy poly-foam. Bio-Core® is durable and long-lasting, so it prevents sags and extends this bed’s lifespan.

Every Amerisleep mattress comes with a 100-night sleep trial and a 20-year warranty.

2. Zoma Mattress

Zoma MattressAnother memory foam mattress to consider is the Zoma. The Zoma is a bed in a box mattress with medium firmness and most comfortable for side sleepers. We like this mattress because it contains Triangulex™ technology to offer excellent zoned support.

The Zoma Mattress has three layers: 2 inches of gel-infused memory foam, 2 inches of Reactiv™, and 7 inches of Support+. Altogether, this bed is 11 inches thick.

The first layer of the mattress is gel-infused memory foam to contour to your body and prevent night sweats. When you lay on the Zoma, this comfort layer molds to your body while the gel within dissipates body heat and feels cool to the touch. Zoma includes their Triangulex™ technology within this layer, too. Triangulex™ offers firm support for your midsection and cushioning comfort for your shoulders and hips to prevent pressure points and maintain neutral spinal alignment.

Below the layer of memory foam is Reactiv™, latex-like poly-foam. Reactiv™ is more responsive than memory foams, so it gives the bed a bit of bounce and reinforces Triangulex™ above to keep you lifted in the mattress. Ultimately, this layer serves as a transition between the soft memory foam above and the sturdy base of the mattress below.

The third and final layer of the Zoma is Support+, a durable poly-foam. As its name implies, Support+ offers extra support to the layers above and prevents sagging.

Zoma is an online-only mattress brand, they offer a 100-night sleep trial and a 10-year warranty with every mattress purchase.

Here we have a green tea memory foam mattress that works well for side sleepers. The bed comes with three inches of memory foam, two inches of comfort foam, and three and a half of high-density airflow foam.

The design of this mattress helps you sleep cool on what is typically a hot mattress. Many people have issues with pure memory foam because they sleep hot, but this one does a great job of eliminating body heat.

This mattress comes with a ten-year limited warranty, and there is no information regarding sleep trials.

Mattress Types to Consider

When you’re looking for the best mattress for acid reflux, it’s important to understand the different types. Some are better for the condition, while others are worse. Let’s take a look.

Memory Foam Mattresses

Memory foam mattresses are some of the most popular because they offer comfort and support to your entire body. These mattresses respond to heat and pressure, when you lay down on a memory foam bed, it’ll contour to your body and offer a “hug-like” feel.

It contours perfectly to your body, and the best memory foam mattresses usually include some cooling technology, as well. That is the primary problem with memory foam. This material retains heat, so if you find yourself sweating on your current mattress, you might not want memory foam unless it has a gel layer built-in.

Latex Mattresses

If you want to combine elements of cooling and comfort, then latex mattresses are a great option. These mattresses usually have a latex foam layer on top of a layer of support foam. It’s important to shop carefully for latex mattresses because some of them may contain harmful chemicals.

You only want to buy a latex mattress if it contains natural latex foam; this natural latex is more expensive, but it’s much healthier.

Innerspring Mattresses

The traditional mattress that we slept on for decades is the innerspring mattress. Over the years, they’ve developed a bad reputation for being uncomfortable and bad for your spine.

There’s some truth to these claims, but there are plenty of falsehoods as well. Purchasing the right innerspring mattress will help you sleep cooler, and it will offer the support your spine needs to stay in alignment.

Another upside to innerspring is their affordability. These are the cheapest mattresses to buy, and they last a long time. Springs are a variety of different metals, and they hold their shape for decades. You can usually flip an innerspring mattress, as well.

Hybrid Mattresses

Hybrid mattresses combine foam layers and innerspring coils to offer cushioning, bouncy comfort. These beds are great for side sleepers who prefer bounce from their mattress because they contain top layers of foam thick enough to provide adequate comfort and pressure relief for the shoulders and hips. However, because hybrids combine many state-of-the-art materials, they often have a higher price tag.

Mattress Budget

Before getting too deep into mattress research, take a step back and determine your budget. Mattresses range in price quite a bit and having a solid budget in mind before heading online or to your local retailer can prevent you from spending more than what you can afford.

We recommend those shopping on a tighter budget search bed in a box mattresses online before heading to a brick-and-mortar retailer. Online mattress brands offer their beds at a fraction of the price of major mattress retailers because they sell direct-to-consumer. Many mattress retailers hike up the prices of their products to ensure all parties make a budget; so you’ll likely pay more than what you would online should you choose to shop in-store.

Sleeping Position

It’s essential to keep your sleep position in mind when choosing a mattress. While side sleepers experience the most relief from acid reflux, you know your body, so choose carefully.

Side Sleepers

People who prefer sleeping on their side need a plush comfortable mattress that will contour to their bodies. The best mattresses for side sleepers are typically medium in firmness and memory foam.

These mattresses are most comfortable for side sleepers because they will fit the shape of your body and relieve pressure points. When you sleep on your side, your hips and shoulders compress into the mattress, so your mattress must be contouring enough to cushion these joints and alleviate tension.

Innerspring mattresses fail side sleepers because they don’t contour well enough. The result is stiffness and soreness because there are gaps between your body and the mattress.

Back Sleepers

If you sleep on your back, you’ll likely benefit most from a firm mattress. While studies say that back sleeping is the best for your body, it’s up to personal preference. This position is best for relieving back pain.

Sleeping on your back offers the widest variety of choices because any mattress will work well for you. If budget is a concern for you, we would suggest choosing an innerspring mattress because you won’t require as much pressure relief as someone sleeping on their side.

Stomach Sleepers

Stomach sleeping is the unhealthiest of all sleep positions because it puts excess stress on your abdomen and lower back. Even if you don’t have acid reflux, we recommend against sleeping this way. However, if you find it hard to change sleeping positions, we recommend firm mattresses for stomach sleepers to keep them in neutral alignment and prevent sagging.

Memory foam mattresses are generally too soft for stomach sleepers, and innerspring mattresses might be challenging to sleep on your stomach due to their stiffness. Typically, stomach sleepers prefer hybrid mattresses.

Sleeping Cool and Airflow

We’re lucky to live in a world where we have an incredible amount of technology to help us sleep cool. Even at a lower price range, you can see that gel-infused memory foam is a popular option.

Companies are putting gel layers in hybrid mattresses, as well. If you have a problem with sleeping hot, you’ll want to ensure that your mattress has a gel layer to help keep you cool.

As we’ve mentioned, memory foam sleeps hot, and that is the number one problem that many people have with it. If you sleep on your stomach or side, you may have experienced this problem before.

For those who sleep on their back, you may not be as concerned with a hot mattress; you might even welcome one.

Either way, if temperature control is an essential factor for you, make sure you choose a hybrid because they contain gel and coils. If you decide to pick a memory foam mattress, make sure it contains a layer of gel on top or has gel-infused foam.

Common Questions

Q: What is the best bed for acid reflux?

A: Sleepers with acid reflux tend to rest on their side. If that’s the case for you, go with a memory foam or hybrid mattress. These offer the best contouring for your body and the support you need to rest well.

Q: How can I improve my mattress for acid reflux?

A: Investing in a wedge pillow or an adjustable bed frame are two ways to help your mattress better improve acid reflux. Both of these sleep accessories allow you to elevate your head, preventing stomach acid from causing heartburn and other discomforts. We should note, though, you only need either a wedge pillow or an adjustable base. Adjustable bases allow you to adjust the angle of your head and feet, so you would not need to pair one of these bed frames with a wedge pillow, too.

Q: Is sleeping on your stomach bad for acid reflux?

A: Sleeping on your stomach is not the best choice for acid reflux. You want to avoid sleeping on your left side because your esophagus is then positioned above the level of your stomach contents, which can aggravate the problem. Sleeping on your right side is ideal for most people.

Q: Does sleeping upright help acid reflux?

A: Gravity helps with acid reflux symptoms. It helps to push stomach acid down and keep it out of the esophagus. When you lay down, you no longer have gravity working to your advantage, which is why most people experience the worst GERD while they’re sleeping or trying to sleep. Make sure you elevate your upper body or consider getting an adjustable base to help keep your head raised.


By now, you should have a complete understanding of how to choose the best mattress for acid reflux. We recommend choosing a memory foam or hybrid mattress because it will work best for side sleeping.

There are plenty of options above. Some are affordable, while others are premium. Choose carefully and enjoy a restful night’s sleep!
