Do Bed Wedges Work for Acid Reflux? Benefits, Tips & What to Know

Nighttime heartburn and regurgitation can quickly ruin a good night's sleep. If you are waking up feeling exhausted because of gastro-oesophageal reflux disease (GERD), you are far from alone. In the UK, approximately 20% of the adult population experiences severe acid reflux (Cleveland Clinic). For many, this constant disruption means fluctuating energy levels, poor metabolic health, and reliance on long-term medications.

If you are looking for a sustainable, non-medication solution to improve your sleep and safeguard your energy, adjusting your sleep posture is a highly effective strategy.

So, do bed wedges work for acid reflux?

This guide explores the science behind elevating your torso, how these orthopaedic supports can dramatically reduce your symptoms, and practical tips for regaining control of your nights.

Do Bed Wedges Really Help With Acid Reflux?

The simple answer is yes.

Gravity and anatomy play massive roles in the occurrence of nocturnal GERD. During the day, gravity naturally keeps your stomach acid where it belongs. When you lie flat at night, a weakened lower oesophageal sphincter allows acid to easily flow backwards into the oesophagus, causing burning pain, coughing, and sleep fragmentation.

A bed wedge provides a gentle, constant incline for your upper torso. By lifting your head and chest between 15cm and 20cm off the mattress, you enlist gravity to keep digestive juices in the stomach.

The clinical evidence backing this is robust:

• Symptom Reduction: A crossover randomised controlled trial found that patients using a bed wedge pillow were significantly more likely to report a clinically meaningful improvement in their symptom scores at 6 weeks (with a risk ratio of 2.1) compared to those lying flat.
• Decreased Acid Exposure: Clinical studies have shown that head-of-bed elevation reduces the overall percentage of time the oesophagus is exposed to stomach acid from 21% down to roughly 15%.
• NHS Endorsement: The NHS recommends raising the head of your bed by 10 to 20cm to manage reflux symptoms naturally.

Using an acid reflux wedge pillow is a proactive, sustainable lifestyle change.

It allows you to protect your oesophageal health while maintaining the deep, restorative sleep necessary for optimal metabolic function and daily energy balance.

How to Choose the Best Wedge Pillow for Acid Reflux

Piling up standard pillows is a common mistake.

Regular pillows only elevate your head, bending your neck and potentially increasing pressure on your abdomen, which can actually force more acid upwards. A proper wedge pillow for acid reflux lifts the entire upper torso to maintain a straight, neutral spine.

When selecting the right product, you should look for a gradual incline and high-quality, supportive materials. Here at Putnams, you can find a range of handmade, UK-manufactured wedges designed specifically for reflux. The Putnams Bed Wedge offers an optimal 15cm (6-inch) height, meeting NHS guidelines perfectly without feeling unnaturally steep.

Depending on your personal comfort preferences, we offer our bed wedges in different widths (from Single up to Super King) and three distinct core materials:

Material Type	Key Features	Best Suited For
Standard Foam	Soft, springy, and highly supportive.	Those looking for reliable, firm support that keeps its shape perfectly over time.
Memory Foam	The top 2.5cm features pressure-relieving memory foam.	Sleepers who want the wedge to contour closely to their body shape, reducing the chance of sliding down.
Graphite Latex	The top 2.5cm uses cooling, natural, hypoallergenic premium Graphite Latex.	Those who tend to sleep hot or prefer natural, anti-bacterial materials for their sleep environment.

How to use a wedge pillow for acid reflux

Even the best bed wedge pillow requires correct usage to maximise its benefits. Transitioning from a flat mattress to an incline can take a few nights to get used to, but following these steps will help you sleep comfortably and sustainably.

• Position it correctly: Place the broad, flat base of the wedge directly on your mattress, with the thickest edge against your headboard or wall. The thinnest part of the wedge should taper down to rest somewhere between your hips and mid-back.
• Combine with left-side sleeping: To supercharge your reflux defence, sleep on your left side. Anatomically, your stomach sits on the left side of your body. Research indicates that maintaining a left lateral recumbent position can reduce oesophageal acid exposure by up to 87%.
• Use your regular pillow: You do not have to give up your favourite head pillow. Simply place it on top of the bed wedge to support your neck just as you normally would.
• Prevent sliding: A common concern is sliding down the incline during the night. Choosing a memory foam top (like the Putnams Memory Foam Bed Wedge) creates more friction and contours to your body, holding you in place. Alternatively, placing a rolled towel or a leg support pillow under your knees can anchor your lower body and relieve pressure on your lower back.

Frequently Asked Questions: Bed Wedges & Acid Reflux

Finding the right sleep solution can be life-changing for those suffering from GERD or silent reflux.

Here are the most common questions our customers ask before choosing a bed wedge.

1. How exactly does a bed wedge help with acid reflux?

The primary benefit of a bed wedge is gravity.

When you lie flat, stomach acid can easily travel into the oesophagus. A bed wedge provides a consistent, 30° to 45° incline that ensures your torso is elevated. This makes it physically harder for acid to travel "uphill," keeping it safely in your stomach while you sleep.

2. Can’t I just use extra pillows to prop myself up?

While stacking pillows is a common DIY fix, it is often counterproductive. Pillows are soft and unstable; they tend to shift during the night and usually only elevate your head and neck. This can cause:

• Neck and back strain due to poor spinal alignment.

• Increased reflux, as "scrunching" your midsection can put extra pressure on the stomach. Our bed wedges provide a firm, gradual incline from the hips upward, protecting both your throat and your posture.

3. What is the recommended height for a reflux wedge?

Clinical studies and sleep experts generally recommend an elevation of 6 to 8 inches (approximately 15cm to 20cm). This height is considered the "Goldilocks" zone, steep enough to prevent acid from rising, but shallow enough to remain comfortable for a full night’s rest.

4. I’m a side sleeper, will a bed wedge work for me?

Yes. Many people worry that a wedge forces you to sleep on your back, but high-quality foam wedges are designed to support side sleepers too.

Note: For the best results, doctors often recommend sleeping on your left side. This position places the stomach below the esophagus, further reducing the chance of acid escaping through the lower esophageal sphincter.

5. Are there other benefits to using a bed wedge?

Absolutely. A Putnams bed wedge is a versatile comfort tool. Beyond treating acid reflux (GERD/GORD) and hiatus hernia, it is highly effective for:

• Respiratory issues: Helping to drain sinuses and ease symptoms of asthma or snoring.

• Post-Surgery Recovery: Providing stable support when you are required to sleep upright.

• Leg Elevation: If placed at the foot of the bed, it can help reduce swelling (oedema) and improve circulation in the legs.

6. Is the Putnams Bed Wedge easy to keep clean?

We know that hygiene is a priority for bedding.

Our bed wedges come with a removable, zipped cover that is machine washable. We also offer replacement covers in various materials, including cooling cotton and waterproof options, to ensure your wedge stays fresh for years.
