Different Types of King Size Mattress Toppers

The type of a King size mattress topper is usually classified by the type of material used to make it. As far as materials are concerned, there are five common materials used to create mattress toppers. With that said, the following are the types of King size mattress toppers to be discussed below:

  • Latex Mattress Topper

When it comes to all-around comfort, this type of mattress topper is the most versatile, and it provides all the benefits you’re looking for in a mattress topper. Benefits include an extra, comfortable cushion for the sleeper. It also offers relief of pressure points that prevent and reduce joint and muscle pain. The mattress also helps with temperature regulation to disperse heat and cool down the body. It is durable and sturdy able to last you up to 20-30 years lifespan. Most importantly, it is hypoallergenic.

There are three types of latex mattress toppers: natural, synthetic, and blended. Latex with 100% natural components is also among the most hygienic types since it is resistant to mildew, mold, and bacteria. It is also the best in terms of quality of softness and overall benefits.

The downside, however, is that this type of mattress topper is usually more expensive than other types.

  • Memory Foam Mattress Topper

This is the most popular type of mattress topper due to its ability to contour with the body shape of the sleeper, eliminate pressure points, and provide other therapeutic benefits. This type also reduces the inconvenience of tossing and turning, which wakes up the sleeper in the middle of the night.

The downside to this type of mattress topper is that it can cause discomfort for the sleeper by being to warm. This is due to memory foams’ ability to absorb heat but being unable to dissipate trapped heat as efficiently as other types.

  • Feather Mattress Topper

Also known as a featherbed, this type is made from duck or goose feather or down.  This type of mattress topper enjoys its share of popularity because of its fluffiness, softness, and being lightweight. It’s very breathable and has excellent temperature regulation, so it helps the sleeper feel cool in summer and warm in winter.

What this type is lacking most notably is that it’s not hypoallergenic. It also has a thin density and poor pressure point relief.

  • Wool Mattress Topper

Like the feather mattress topper, this type has impressive breathability and temperature regulation. However, unlike the former, the latter is hypoallergenic. Because it is purely organic and does not use chemicals, it is free from toxic smells, unlike memory foam mattress toppers.

Its downsides include being unable to reduce motion transfer, which could be very inconvenient if the sleeper has a partner that is also sleeping in the same bed. You will also need to continually shake or fluff it to maintain its loft.

  • Fiber Mattress Topper

Also known as a fiberbed, it exhibits similarities with the feather mattress topper. Its benefits include reduced pressure points, no toxic chemical smell, excellent temperature regulation, having low weight, and being hypoallergenic. The best advantage this type could offer is that it is usually the cheapest type of mattress topper in the market.

Significant drawbacks include inefficiency at reducing motion transfer, a constant need to fluff it to maintain its comfort, and it can become lumpy after machine wash.

Key Features To Look For When Buying A King Size Mattress Topper

When looking for the ideal King size mattress topper, there are a lot of factors to weigh in. Regardless of budget, the following features should be taken into careful consideration:

  • Durability

To make sure you get your money’s worth, you should take note of how durable the mattress topper is. Knowing what type of mattress topper is durable and which ones aren’t, makes a huge difference most especially if you use it a lot.

However, some mattress toppers of the same type are more durable than the rest, so it’s essential to also keep a keen eye on the build quality of every product.

  • Breathability

It’s a great inconvenience to your sleep when you’re feeling hot and flushed. Getting a mattress topper that has well-ventilated features or made using highly breathable materials can make a huge difference in your comfort. The breathability of a mattress topper is also influenced by how dense it is, so it’s essential to pay heed in regards to a topper’s density as well.

  • Thickness

The thickness of mattress toppers depends on how much adjustments you’d want to make for your mattress. If you have a firm mattress and you want something more conforming to your body’s shape, you might want to get a thicker memory foam mattress topper. For minor adjustments, thinner mattress toppers usually do the trick.

  • Density

The higher the density, the better the support a mattress topper can provide. It also aids in delivering closer conformity to the sleeper’s body shape. Having a higher density means that it has more material in a given area or measurement and fewer air bubbles, as opposed to thickness.

You should take note that using high-density mattress toppers come with the inconveniences of sleeping on a hotter and noisier sleeping surface. It usually comes with a chemical odor that you need to air out for a few hours or even days.

  • Firmness

As an extra, removable layer of cushion, mattress toppers can be used to fix the comfort level of the mattress you currently have without the need to buy a new one. Knowing what type of sleeper you are is essential so that you won’t make the mistake of choosing the wrong firmness or softness. Both back and stomach sleepers usually prefer medium to medium-firm firmness, while side sleepers prefer sleeping on soft to medium-soft.

  • Irritants

It is essential to know if you have skin sensitivities. Materials such as latex and feathers can cause skin allergies to some people. These types of mattress toppers will cause inconveniences if you find out you’re actually allergic to those materials. If you’re unsure, it’s always a safe bet to choose hypoallergenic options.

  • Maintenance

Easily one of the most overlooked key features in some products, maintenance determines how easy it is to clean and keep the mattress topper hygienic.  Some types of mattress toppers are not machine washable, so you have to know what recommendations the seller or manufacturer suggests for its maintenance.

Some mattress toppers also come with a cover while some do not. Memory foam and latex types do not come with a lid but you can use your bedsheets instead. Wool, feather, and fiber mattress topper types usually come with a fabric cover and can be used with or without a bedsheet.

The lifespan of the mattress topper is significantly higher the easier it is to clean and maintain it.

Frequently Asked Questions

  • Is there a need to put a mattress cover or bed sheet on top of a King size mattress topper?

This depends on the type of mattress topper. Some latex and memory foam mattress toppers come as unprotected and uncovered cushioned toppers for your mattresses. Not only would this feel uncomfortable to use when they’re uncovered, but it would also make them more prone to damage. Therefore, it’s advisable to use a cover or sheet for these types of toppers. However, for mattress toppers that are protected with covers, it is a matter of preference if you want to use a cover or not.

  • Why is there a smell on my mattress topper, and how can I get rid of it?

This is a reaction known as “off-gassing” that occurs commonly on memory foams and synthetic latex foams. This happens when volatile organic compounds break down and release gas. The foul smell usually subsides after a day or a few. The process can be sped up by putting the topper out in the sun for a day or two and then let it expand entirely before using it.

  • Why is there no smell on 100% natural latex mattress toppers, but there are is a chemical smell for synthetic or blended latex ones?

Natural latex doesn’t produce off-gassing because they are completely 100% natural, unlike its synthetic and blended variants that contain chemicals.

  • Is it advisable to flip the mattress topper once in a while?

Unlike mattresses, there is no need to flip the mattress topper. You may do so if you like, but it is unnecessary or can’t be done with some toppers. However, you can rotate it once in a while to prevent it from sagging. This is because an uneven surface can form from prolonged use when you sleep exclusively on one particular part of the surface.

Conclusion

A King size mattress topper can help solve your sleeping problems without replacing your mattress. It also provides various benefits, such as providing an extra layer of comfort for you and an extra layer of protection for your mattress. It can also provide your favorite mattress an even longer lifespan.

Budget and types aside, what makes the best King size mattress toppers are your preferences. Knowing what type of sleeper you are is just the tip of the iceberg. There may be conflicting key features you’re weighing in a mattress topper in regards to the type. Still, it all comes down to prioritizing needs. Fortunately, this detailed guide narrows down the key features to help you discern for yourself the ideal topper for your King size mattress.
