Quick Answer: To make a bed wedge pillow last up to 10 years, never machine wash or submerge the foam core. Instead, wash the removable cover regularly, spot clean the foam with a mild solution, deodorize with baking soda, and use a waterproof protector. Consistent monthly maintenance is the single biggest factor in preserving foam structure and hygiene long-term.
A quality bed wedge pillow is not just another sleep accessory. For the estimated 20% of Americans living with GERD (according to the National Institutes of Health), the 32.4% of U.S. adults diagnosed with obstructive sleep apnea (according to a 2024 study published in Respiratory Medicine), and the millions recovering from surgery or managing chronic back and neck pain, a bed wedge is a daily therapeutic tool. Replacing it every year or two is expensive. Keeping it in peak condition for a decade is entirely achievable, with the right approach.
Our Bed Wedge Pillow is handmade using high-density foam (available in original or memory foam filling), comes with a removable, zipped, washable cover, and is backed by a 2-year guarantee. But proper care can extend performance well beyond that guarantee period. This guide walks you through exactly how to do it.
The Golden Rule: Cover Washing vs. Foam Core Care
Before you reach for any cleaning product, understand this single critical distinction: the outer cover and the inner foam core require completely different care.
Mixing up these two approaches is the most common mistake wedge pillow owners make, and it can permanently destroy the foam's structural integrity within a single wash cycle.

Inner foam core (memory foam or high-density foam) |

Spot clean only, never submerge |
Why can't foam go in the washing machine? Memory foam and high-density polyurethane foam are porous, open-cell materials. When submerged in water, these cells absorb moisture like a sponge, moisture that cannot be effectively removed by standard drying. The result is trapped dampness inside the core, creating an environment for mold, mildew, and bacterial growth. Water also breaks down the cellular polymer structure, causing the foam to lose its supportive incline and contouring properties permanently.
This is not a cautionary tale, it is a hard technical limit. Machine-washing or soaking a memory foam wedge core will void most manufacturer warranties and render the pillow unsupportive within weeks.

Step-by-Step: How to Wash Your Bed Wedge Cover
Our bed wedge comes with a removable, zipped cover designed to be washed regularly. Washing it consistently is your first line of defense against sweat, body oils, dust mites, and acid reflux residue reaching the foam.
How often should you wash your bed wedge cover?
- If you use it nightly for acid reflux, snoring, or post-surgical recovery: every 1-2 weeks
- General use: every 2-3 weeks at minimum
Washing instructions:
- Unzip carefully. Pull the zipper slowly to avoid snagging the teeth or tearing the fabric at the foam's corners.
- Pre-treat stains. Apply a small amount of mild liquid detergent or an enzyme-based stain remover directly to any visible stains, particularly useful for removing acid reflux stains from a wedge pillow cover. Let it sit for 10-15 minutes before washing.
- Machine wash on a gentle, cool cycle. Use a mild detergent. Avoid chlorine bleach (it degrades fabric fibers) and fabric softener (it leaves a film that reduces breathability over time).
- Dry thoroughly before reattaching. Air-dry where possible, or tumble dry on a low-heat setting. Never put the cover back on the foam core while it is still damp, residual moisture transfers directly into the foam and creates mildew.
Our Additional Bed Wedge Cover is an excellent investment for this reason. Having a spare means your wedge is never left uncovered while the first cover dries.
How to Spot Clean and Deodorize Memory Foam Safely
Even with a diligent cover-washing routine, the inner foam core will eventually accumulate atmospheric odors, dust, and occasional accidental spills. Here is how to address each safely.
Monthly vacuuming and airing
This is the single most impactful maintenance habit you can develop. Dust mites, responsible for 70% of all respiratory allergies according to Allergo Medik, accumulate in foam materials over time. A monthly vacuum removes them before they build up.
- Remove the outer cover completely
- Use your vacuum's soft upholstery attachment on all sides of the exposed foam
- Place the foam near an open window or in a shaded outdoor area for 2–3 hours to air out
Important: Keep the foam out of direct, prolonged sunlight. UV rays accelerate the oxidation of polyurethane foam, causing yellowing and structural degradation. Brief indirect sunlight exposure is fine; extended direct sun is not.
Spot cleaning accidental spills
Act quickly.
Fresh spills are significantly easier to treat than dried stains.
Follow these steps:
|
Step |
Action |
Key tip |
|---|---|---|
|
1. Blot immediately |
Press a clean white cloth or paper towels firmly into the foam |
Do not rub, rubbing forces liquid deeper into foam cells |
|
2. Mix a gentle solution |
Combine cool water with a few drops of mild dish soap |
Keep the solution light; avoid harsh chemical cleaners |
|
3. Apply minimally |
Dampen a cloth in the solution, wring completely, then dab the spot |
The foam should never feel saturated |
|
4. Rinse and dry |
Dab with a fresh damp cloth to remove soap, then press dry towels to absorb moisture |
Use a fan pointed at the area; allow 24-48 hours to dry fully |
Never reattach the cover until the foam is 100% dry.
Eliminating stubborn odors
Body heat, night sweats, and extended use can cause odor buildup in the foam. Baking soda is the safest and most effective solution:
- Dust a generous layer of baking soda across the entire exposed foam surface
- Leave it for 4-6 hours (baking soda draws out moisture and neutralizes acidic odors)
- Vacuum up all residue thoroughly using the upholstery attachment
This method is particularly relevant for those using a wedge to manage acid reflux or GERD, conditions where nighttime stomach acid exposure can leave trace residue on the foam surface over months of use.

Preventative Maintenance: Protecting Your Wedge for a Decade
Getting 10 years of performance from your wedge pillow requires a proactive approach, not just reactive cleaning.
1. Invest in a waterproof wedge protector
A breathable, waterproof wedge pillow protector placed beneath the standard cover is the most effective single upgrade for long-term maintenance. Modern polyurethane-backed protectors block sweat, saliva, and spills without the crinkling noise associated with older waterproof covers. They create a full barrier between your body and the foam, dramatically reducing how often the core needs attention.
Consider layering your protection:
- Layer 1: Waterproof foam protector (directly on the foam)
- Layer 2: Your washable zip cover (our cover or an Additional Bed Wedge Cover)
2. Rotate regularly
You should not fold or bend a firm foam wedge, doing so damages the internal structure. However, rotating the pillow 180 degrees every few weeks helps distribute body weight across the entire slope surface evenly. This prevents deep body impressions from forming in one area over time.
3. Store correctly when not in use
If you ever need to store your bed wedge temporarily:
- Clean and fully dry it first; never store damp foam
- Store flat in a cool, dry, well-ventilated area
- Avoid compression; do not vacuum-seal or place heavy items on top. Prolonged extreme compression damages memory foam's recovery capabilities permanently
- Keep away from damp basements and hot attics; extreme humidity causes foam degradation; excessive heat compromises foam elasticity
4. Wash your pillowcase and bedding weekly
While this applies to your full sleep setup, it directly impacts wedge hygiene. Weekly bedding washes reduce the transfer of oils, dead skin cells, and allergens onto your wedge cover, extending the time between cover washes without compromising cleanliness.

When Is It Time to Replace Your Bed Wedge Pillow?
Even with meticulous pillow maintenance, all foam reaches the end of its functional life.
Our bed wedge pillow is built from high-density foam to last, and the 2-year guarantee reflects that confidence. With proper care, many users find performance extends significantly beyond that period.
Replace your bed wedge if you notice any of the following:
- Permanent sagging: The foam no longer returns to its original incline. Your torso sinks too low, reducing the therapeutic elevation angle
- Return of symptoms: If your GERD, snoring, or back pain symptoms suddenly worsen without any other explanation, the foam may have lost its structural density
- Crumbling or hardening: Brittle, flaking, or unusually hard foam indicates material degradation
- Persistent odor: Odors that remain after baking soda treatment suggest deep microbial penetration that cannot be resolved with surface cleaning
- Visible mold: Any visible mold growth requires immediate replacement
If you identify these signs early, replacing your cover before the foam, may temporarily extend usability. But once the foam core is compromised, a full replacement is the right call for your sleep health.

Frequently Asked Questions
Can you machine wash a bed wedge pillow?
No. The foam core of a bed wedge pillow, whether memory foam or high-density foam, must never be machine washed or submerged in water. Doing so permanently destroys the foam's cellular structure and creates conditions for mold growth. Only the removable outer cover is machine washable. Wash it on a cool, gentle cycle with mild detergent and air-dry before reattaching.
How often should you wash a bed wedge pillow cover?
For people using a bed wedge nightly to manage acid reflux, GERD, or snoring, washing the cover every 1-2 weeks is recommended. For general use, every 2-3 weeks maintains adequate hygiene. Having a spare bed wedge cover allows you to wash one while the other is in use, so your wedge is never left uncovered.
How do you remove stains from a wedge pillow cover?
Pre-treat visible stains, including acid reflux stains, by applying a small amount of enzyme-based stain remover or mild liquid detergent directly to the stain. Allow it to sit for 10-15 minutes before machine washing on a gentle, cool cycle. For stains on the foam core itself, dab (never rub) with a cloth dampened in a mild soap and cool water solution, then air-dry for at least 24-48 hours.
Why is my memory foam wedge pillow turning yellow?
Yellowing of polyurethane foam is caused by UV exposure and natural oxidation over time. According to foam chemistry, this is an expected characteristic of the material and does not affect performance or safety. To slow yellowing, keep the foam core covered at all times and avoid prolonged exposure to direct sunlight during airing.
How do you get rid of odors in a memory foam wedge pillow?
Sprinkle a generous layer of baking soda across the exposed foam surface and leave it for 4-6 hours. Baking soda absorbs moisture and neutralizes acidic odors naturally. Vacuum up the residue thoroughly using an upholstery attachment. For persistent odors, repeat the process or increase the contact time to overnight.
How long does a bed wedge pillow last with proper care?
A quality high-density foam bed wedge, like ours from bedwedge.com, can last well beyond its 2-year guarantee with consistent maintenance. Regular cover washing, monthly vacuuming, careful spot cleaning, and the use of a waterproof protector are the four practices most strongly associated with extended foam life. Signs that replacement is needed include permanent sagging, foam crumbling, or the return of previously managed symptoms like nighttime reflux.
What is the best replacement cover for a bed wedge pillow?
The best replacement cover for a bed wedge pillow is one designed specifically for the wedge's dimensions and slope, a standard pillowcase will not fit correctly. Our Additional Bed Wedge Cover is made to fit the bedwedge.com range precisely, with a zipper closure for easy removal and machine-washable fabric. Choosing a custom-fit, breathable cover preserves both the foam and your sleep hygiene.
