Choosing Your Perfect Under-Mattress Bed Wedge: A Buyer’s Guide
An under-mattress bed wedge is a simple but smart tool. It goes beneath your mattress to gently raise the head of your bed. This slight incline can help with snoring, acid reflux, and general comfort while reading or watching TV. Finding the right one is easy when you know what to look for.
Key Features to Look For
When shopping, focus on these important features:
- Incline Angle: This is how steep the slope is. Most wedges offer angles between 7 and 12 inches of height. A steeper angle (higher number) helps more with severe reflux or snoring. Start lower if you are new to wedges.
- Length and Width: The wedge must fit well under your mattress. Measure your bed first! A good wedge should extend across most of your mattress width but not hang over the edges.
- Support Consistency: The wedge must hold its shape. It should not sag in the middle when the weight of the mattress and you press down on it.
- Cover Material: While the wedge itself is foam, the cover matters for breathability and cleaning. Look for removable, washable covers.
Important Materials Matter
The material of the core support is crucial for long-term use.
Foam Types
- High-Density Polyurethane Foam: This is the most common choice. High-density foam resists breaking down over time. It offers firm, reliable support. Lower density foam breaks down fast, creating a dip where the wedge should be.
- Memory Foam Layer: Some wedges add a top layer of memory foam. This layer contours slightly to your body, increasing comfort while keeping the overall incline firm.
- Certifications: Look for foams certified by organizations like CertiPUR-US. This means the foam is made without harmful chemicals, which is safer for your bedroom air quality.
Factors That Improve or Reduce Quality
Quality is not just about the price tag. It is about how long the wedge lasts and how well it works.
What Boosts Quality:
- Firmness Rating: A firmer wedge supports the mattress better. A soft wedge just sinks under the weight.
- Tapered Edges: Quality wedges often have edges that gently taper down. This stops you from feeling an abrupt “shelf” where the wedge ends under the mattress.
- Non-Slip Base: Some wedges include a rubberized bottom. This stops the wedge from sliding down toward the foot of the bed when you adjust your position.
What Lowers Quality:
- Off-Gassing Smell: Cheap foam often releases a strong chemical smell when first opened. Good quality foam minimizes this.
- Thin or Loose Covers: A thin cover rips easily or bunches up, making the surface uncomfortable.
User Experience and Use Cases
How you plan to use your wedge affects which size and angle you need. The wedge works by subtly lifting the entire upper third of your mattress.
Common Uses:
- Acid Reflux (GERD): Doctors often recommend elevating the head of the bed by 6 to 8 inches. This angle helps keep stomach acid down while you sleep.
- Snoring Relief: Raising the head opens airways, which can reduce vibrations that cause snoring.
- Post-Surgery Recovery: Doctors may suggest sleeping slightly elevated after shoulder or certain abdominal surgeries.
- Reading and Watching TV: The wedge creates a comfortable incline, removing the need to stack many pillows, which often bunch up uncomfortably.
Remember, the wedge goes under the mattress. You should not feel a hard edge digging into your back. The incline should feel smooth and gradual across your body.
10 Frequently Asked Questions (FAQ) About Under-Mattress Bed Wedges
Q: What is the main difference between a bed wedge and a wedge pillow?
A: A bed wedge is a large foam block placed under your mattress to lift the entire head section. A wedge pillow sits on top of the mattress for support.
Q: Will an under-mattress wedge work with my adjustable bed?
A: Generally, no. Adjustable beds move the mattress mechanically. Placing a large foam wedge underneath can strain the motors or prevent the bed from folding correctly.
Q: How do I clean the under-mattress wedge?
A: You usually cannot wash the foam core. Spot clean the foam if needed. Focus on removing the outer cover, which should be machine washable according to the manufacturer’s instructions.
Q: Do I need to buy a wedge that matches my mattress size (Twin, Queen, King)?
A: Yes, size matters for coverage. If you buy a wedge meant for a Twin bed and use it on a King, it will only lift a small area in the center, creating an uneven dip.
Q: Will this wedge make my bed too hot?
A: The wedge itself does not trap heat because it is under the mattress. However, if the wedge is very dense and your mattress is thin, it might slightly affect airflow directly under the foam.
Q: How long does it take to get used to sleeping on an incline?
A: Most people adjust within one to three nights. If you feel neck strain, your angle might be too steep, or the wedge may not be wide enough to support your shoulders evenly.
Q: Can I use a wedge if I sleep on my stomach?
A: It is not recommended. Bed wedges are designed to support the natural curve of your spine when you sleep on your back or side. Stomach sleeping is discouraged by most sleep experts regardless of the wedge.
Q: What is the minimum height recommended for acid reflux relief?
A: Medical professionals often suggest an incline of at least 6 inches for effective gravity assistance against reflux.
Q: What happens if the wedge is too firm?
A: If the wedge is too firm, you might feel a noticeable ridge or pressure point under your hips or upper back. Look for models that include a memory foam topper for added cushioning.
Q: If the wedge moves, what stops it from sliding?
A: A quality wedge should have a non-slip or rubberized surface on the bottom that grips the box spring or bed frame. If yours slips, you can try placing a thin, non-slip rug pad between the wedge and the bed base.
