Benefits of a Thick Mattress Topper
Thick mattress toppers change how your current mattress feels. However, there are more benefits to them. Check below.- Cushioned Support – Thick toppers add cushioning, which side sleepers often like at the shoulders and hips. Stomach sleepers may sink too far into a very soft, thick topper.
- Durable – A thicker topper has more material, so small dips may be less noticeable.
- Cost Effective – These toppers are not as costly as a brand-new mattress but can noticeably change how your bed feels.
- Multiple Options – Thick mattress pads come with different filling materials. So you have plenty of options to choose from.
How to Choose a Thick Mattress Topper
Here are the most important aspects worth checking.- Filling Types – Different fillings serve different purposes and deliver different comfort levels. For instance, memory foam contours for pressure relief, feathers feel lofty, and synthetic fills are an option if you’re allergic to down.
- Thickness – If your mattress needs a big change, look at toppers 4 inches or thicker. Even a 3-inch topper may do the trick if you need a minor lift.
- Specific Features – You might also be looking for specific benefits from your topper. For example, go for a cooling topper if you sweat a lot. If you have a dust mite allergy, add an allergen-barrier cover and wash bedding weekly in hot water.[1]
- Securing Method – Toppers can be secured with straps or fitting pockets on the mattress. Choose the one you like.
Thick Mattress Topper Maintenance Tips
Check these cool tips that will help you increase the life of your thick mattress pad.- Wash Interval – Wash the removable cover often, and follow the care label for the topper itself.
- Avoid Washing Machine – Foam toppers shouldn’t go in the washer; only wash a cover or fiber pad when the care label allows it.
- Life Span – Though different mattress toppers have different life spans, many last about 3 to 5 years.
- Natural Drying – Instead of tumble dry, prefer letting your topper dry naturally. This is advisable if your topper has wool, latex, or memory foam filling.
