Knowing how to wash a Tempur Pedic mattress cover is essential for keeping your sleep sanctuary clean and hygienic. These covers, often called “knit” or “stretch” covers, are designed to protect the mattress core, but they do need regular cleaning from spills, sweat, and dust. This guide will walk you through the exact, manufacturer-recommended steps to do it safely.
Washing it wrong can lead to shrinkage, damage to the materials, or voiding your warranty. We’ll cover everything from pre-treating stains to drying methods, so you can maintain your investment and sleep on a fresh, clean surface.
How To Wash A Tempur Pedic Mattress Cover
First, a crucial note: Always, always check the care label attached to your specific mattress cover. Tempur-Pedic’s official guidance is the final authority, as materials can vary slightly between models and years. The following instructions are based on their general recommendations for most removable knit covers.
What You’ll Need
- Mild liquid detergent (avoid powders, bleach, or fabric softeners)
- Cold or warm water
- A stain remover (optional, for tough spots)
- A large-capacity washing machine (commercial-sized is best)
- A large-capacity dryer or a space for air-drying
Step-by-Step Washing Instructions
1. Remove the Cover Carefully
Unzip the cover slowly and gently peel it away from the memory foam mattress. Be careful not to tug or pull on the fabric too hard, as the seams are strong but not indestructible. It’s a good idea to have someone help you, especially with larger mattresses like king or California king sizes.
2. Pre-Treat Any Stains
Before the cover goes in the wash, spot-clean any visible stains. Apply a small amount of mild detergent directly to the stain and gently rub it in with a soft cloth. Let it sit for about 10-15 minutes. For organic stains like sweat or blood, cold water is you’re best first step.
3. Load the Washing Machine
Place the cover in the washing machine by itself. Do not wash it with other items like sheets or towels. The zipper or seams could snag on other fabrics, and the heavy, wet cover can throw off the machine’s balance.
4. Choose the Correct Settings
This is the most important step. Set your machine to:
- Water Temperature: Cold or warm water only. Never use hot water, as it can cause significant shrinkage.
- Cycle: Use a gentle or delicate cycle with a slow spin speed.
- Detergent: Use a small amount of mild, liquid detergent. Half the usual amount is often plenty.
5. Start the Wash Cycle
Double-check your settings and start the machine. Listen during the spin cycle; if it sounds violently off-balance, you may need to pause and redistribute the cover inside the drum.
Drying Your Mattress Cover Thoroughly
Proper drying is just as critical as washing. Never, ever put a Tempur-Pedic mattress cover in the dryer on a high heat setting. High heat is the fastest way to ruin it.
Recommended Drying Method: Air Dry
Tempur-Pedic recommends air drying whenever possible. Lay the cover flat on a clean, dry surface, or drape it over several clotheslines or banisters. Ensure good air circulation around it. Flip it occasionally to let both sides dry completely. This can take 24-48 hours depending on humidity.
Alternative: Tumble Dry Low
If you must use a dryer, use only the absolute lowest heat setting (sometimes called “air fluff” or “no heat”). Toss in a couple of clean, dry towels to help absorb moisture and balance the load. Check it every 15-20 minutes, removing it while still slightly damp to finish air-drying flat. This prevents the edges from curling.
Putting the Clean Cover Back On
Once the cover is completely, 100% dry, you can put it back on the mattress. Start by aligning the zipper at the foot of the bed. Slowly work the cover over each corner, smoothing it out as you go to avoid bunching. Zip it up carefully, ensuring no part of the mattress foam gets caught in the zipper teeth.
How Often Should You Wash the Cover?
It’s a good practice to wash your mattress cover every 2-3 months. Of course, you should wash it immediately after any liquid spill or accident. Regular washing helps control allergens like dust mites and keeps your sleeping environment fresh.
What NOT to Do
- Do not dry clean. The chemicals used can damage the fabric and underlying foam.
- Do not use bleach or harsh chemicals. They can break down the fibers and void your warranty.
- Do not iron or steam. The heat can melt or distort the fabric.
- Do not wring or twist the cover to remove water; let the spin cycle or air drying do the work.
Dealing with Non-Removable Covers
Some older or specific Tempur-Pedic models have a cover that is not designed to be removed. In this case, surface cleaning is you’re only option.
- Vacuum the cover thoroughly to remove dust and debris.
- Mix a solution of cold water and a tiny bit of mild detergent.
- Dampen a clean white cloth (never soak it) and gently blot the stained area.
- Use a second cloth dampened with only cold water to rinse the spot.
- Blot dry with a towel and allow to air dry completely before making the bed.
Protecting Your Mattress Cover
To extend the time between washes, use a waterproof mattress protector. A high-quality protector acts as a first line of defense against spills, sweat, and stains. It’s much easier to toss a protector in the wash weekly than the entire mattress cover. Just ensure it’s breathable so it doesn’t change the feel of your TEMPUR material.
When to Contact Customer Service
If you encounter a major stain that won’t come out, or if the cover shrinks or damages despite following these steps, contact Tempur-Pedic customer service. They can provide model-specific advice and, if needed, information about replacement covers. Keep your receipt and warranty information handy.
FAQ Section
Can I wash my Tempur-Pedic mattress cover in hot water?
No, you should not. Always use cold or warm water on a gentle cycle. Hot water can cause the spandex or polyester blend to shrink dramatically, making it impossible to refit on your mattress.
Can you put a Tempur-Pedic mattress cover in the dryer?
It’s not recommended, but if you must, use only the no-heat or air fluff setting. The best method is always to air dry the cover flat or draped over lines. High heat will damage it.
How do you get stains out of a Tempur-Pedic mattress cover?
Pre-treat stains before washing. Use a small amount of mild detergent or an enzyme-based stain remover for biological stains. Gently dab, don’t scrub, and let it sit before washing on cold. For non-removable covers, use the blotting method with a damp cloth.
What is the best way to dry a Tempurpedic mattress cover?
Air drying is definitly the best way. Lay it flat in a well-ventilated area out of direct sunlight, which can fade the fabric. Flip it periodically to ensure both sides dry completely, which prevents mildew.
Why did my mattress cover shrink?
Shrinkage almost always occurs from exposure to high heat, either in the wash (hot water) or in the dryer. Unfortunately, once shrunk, it’s very difficult to reverse. Always adhere to cold/warm wash and air-dry instructions.
Can I use vinegar to clean my mattress cover?
While vinegar is a natural cleaner, it’s not recommended by Tempur-Pedic. The acidity could potentially affect the fabric’s composition or the foam underneath if it seeps through. Stick to mild detergents and cold water for safety.
Keeping your Tempur-Pedic mattress cover clean doesn’t have to be stressful. By following these simple steps—gentle wash, cold water, and air drying—you can preserve its fit, feel, and function for years to come. Regular maintenance protects your mattress investment and ensures you have a healthy, comfortable place to sleep every single night. Remember, when in doubt, refer to the tag on your specific cover or reach out to the manufacturer for the most accurate care advice.
