Will an Electric Blanket Damage a Memory Foam Mattress? With winter coming, many people are interested in ways to stay warm in bed without cranking up the thermostat. Electric blankets provide cosy warmth at an affordable price. But if you have a memory foam mattress, you may be wondering if the heat from an electric blanket could damage the material and reduce its effectiveness. Let’s take a closer look at whether electric blankets are safe for memory foam.
How Do Memory Foam Mattresses Work?
Memory foam, also known as viscoelastic foam, was originally developed by NASA to cushion aircraft seats. It has become popular in mattresses due to its ability to conform to the sleeper’s body shape and relieve pressure points.
Memory foam contains temperature-sensitive polyurethane along with other chemicals that allow it to soften in response to body heat. As you lie on a memory foam mattress, your body heat causes the foam to mould around your shape. This cradling effect helps align the spine and alleviate aches and pains.
Once pressure is removed, high-quality memory foam will slowly return to its original form. This springback allows the material to retain its supportiveness night after night. Lower-density foams may fail to recover quickly, leaving long-lasting body impressions.
Can Electric Blankets Damage Memory Foam?
Most memory foam mattress manufacturers state that electric blankets will not harm their mattresses when used as directed. However, there are a few factors to keep in mind:
- Density – Higher density foams that fall between 4 to 6 lbs per cubic foot tend to be more resilient to heat. Lower-density foams under 4 lbs are more susceptible to becoming excessively soft.
- Quality – Well-made memory foam created through a closed moulding process can better withstand repeated heating. Cheaper foams made with an open-cell process may degrade faster.
- Firmness – Firm or extra-firm mattresses maintain their shape better with added heat. Plush and medium-soft mattresses are more likely to become too soft.
- Overheating – Excessive and prolonged heat can break down the polyurethane structure of lower-quality foams. This can lead to permanent impressions.
- Electric blanket features – Blankets with adjustable heat settings and auto-off timers are safest. Avoid placing thick blankets directly on the mattress.
Precautions When Using Electric Blankets on Memory Foam
To get the most life out of your memory foam mattress when using an electric blanket, keep these precautions in mind:
- Use a mattress protector as a barrier between your electric blanket and mattress.
- Choose blankets with low, medium, and high heat settings. Keep it on low.
- Don’t bundle or fold the blanket, which can cause overheating in spots.
- Use a timer and shut off the blanket before falling asleep.
- Place blankets above-fitted sheets and below top sheets or duvets.
- Never operate an electric blanket while folded or stacked.
- Inspect often for damage and cease use immediately if any is found.
- Follow all manufacturer instructions carefully.
Alternatives to Electric Blankets
If you remain concerned about using an electric blanket with your memory foam mattress, other options for staying cosy include:
- Plush mattress toppers add softness and insulation.
- Flannel sheets feel deliciously warm and cosy.
- Comforters and duvets provide lighter warmth than blankets.
- Warm sleepwear like socks, robes, and pyjamas.
- Hot water bottles offer temporary warmth without wires.
- Turning up the thermostat a few degrees at night.
Conclusion
Quality memory foam that hasn’t already broken down or become overly soft can generally withstand the occasional, careful use of an electric blanket. To keep your mattress in top condition for years to come, invest in one with a density of over 4 lbs, use moderate heat, place a protector between it and your mattress, and turn it off before falling asleep. Then you can enjoy winter nights that are as cosy as they are comfortable.
Frequently Asked Questions About Electric Blankets and Memory Foam Mattresses
Q: Will an electric blanket ruin my memory foam mattress?
A: It’s unlikely that the occasional use of an electric blanket on low to medium heat will ruin a quality memory foam mattress. However excessive, prolonged heat exposure can break down cheaper polyurethane foams over time leading to impressions and sagging.
Q: Is it safe to use an electric blanket with memory foam?
A: Yes, electric blankets are generally safe for memory foam mattresses when used properly in the correct setting and not left unattended overnight. Always follow manufacturer guidelines.
Q: Where should I place an electric blanket on a memory foam mattress?
A: For a fitted electric blanket, place it above the fitted sheet and below the top sheet or duvet to allow it to work best. For non-fitted blankets, place it above all bedding. Never operate an electric blanket folded or bunched up.
Q: Can I use an electric blanket under memory foam mattress toppers?
A: You can, but it’s not ideal. The wires and thickness of the blanket may reduce the conforming effects of the topper. Use a low heat setting and place it above the topper instead.
Q: What’s the best electric blanket for a memory foam mattress?
A: Look for blankets with adjustable heat settings and an auto shut-off feature. Thinner blankets that don’t bunch up work best. Avoid thick heated mattress pads.
Q: Can I use an electric blanket on a Tempur-Pedic mattress?
A: Tempur-Pedic suggests using electric blankets on top of the mattress only on low settings for no more than 30 minutes to retain the material’s contouring properties.
Q: Is it safe to use a heating pad on a memory foam mattress?
A: No, it’s best not to use a heating pad designed for sore muscles directly on memory foam. The concentrated heat in one area can damage the foam.
Q: Can I put an electric blanket under a memory foam mattress topper?
A: You can, but the wires and thickness may reduce the topper’s conforming effects. Use a low heat setting and place it above the topper instead.
Q: Will memory foam get too hot with an electric blanket?
A: It’s possible. To prevent overheating, use lower heat settings, don’t bundle the blanket, and turn it off before falling asleep. Monitor temperature closely.
Q: Can I use a hot water bottle on memory foam?
A: No, it’s best to avoid hot water bottles on memory foam altogether as the focused heat and moisture can damage the mattress. Use electric blankets as directed instead.
Q: Will washing an electric blanket damage memory foam?
A: Washing an electric blanket according to the manufacturer’s instructions will not harm your memory foam mattress. Just let the blanket fully dry before using it again.
Q: Is there an alternative to an electric blanket on memory foam?
A: Options like mattress toppers, flannel sheets, warm duvets, sleepwear, and turning up the thermostat a few degrees can help keep you cosy without an electric blanket.
Q: I have a memory foam pillow – can I use an electric blanket?
A: Yes, you can safely use a memory foam pillow with an electric blanket as your head does not directly contact the blanket for prolonged periods of time.
Q: Can you use an electric blanket with a gel memory foam mattress?
A: You can use an electric blanket safely with gel memory foam. Follow the same precautions in terms of heat settings and timers. The gel infusion helps regulate temperature.
