Best King Size Mattress Toppers

A mattress topper is a padding that you can add on top of your mattress to give it more support and comfort. It's usually made from foam, down, or synthetic materials and can range in thickness from two to four inches.
You might need an alternative mattress topper if you're not getting enough support from your mattress. A firm mattress can lose its firmness due to old age, mishandling, and other factors. In this case, if you purchase a firm mattress topper, you'll be able to get all the support you need from the mattress.
On the other hand, if you have a medical condition that requires additional support, or you want a softer surface, but your mattress is too firm, then a soft topper will do the trick. Other than the feel of your sleep surface, you may also want a mattress topper if you're a hot sleeper and your mattress has no cooling features.
To keep your body from sweating all night and tossing due to discomfort, purchase a gel memory foam mattress topper that will steal the heat away from your body as you sleep. The same goes for cold sleepers in need of a warm surface.

How to choose the right mattress topper
What should you consider when browsing for mattress toppers? Below are three main factors.
The material used to construct the topper makes a whole difference in how it turns out and its functionality. There are mattress toppers made from latex, wool, down, and feathers, among other materials. The most popular mattress topper is the one made from memory foam as it provides excellent support for the body and contours to the shape of your body perfectly. Unfortunately, memory foam mattress toppers tend to be warm and won't fit hot sleepers and summer nights. A solution here is to get a gel-infused memory foam topper that dissipates heat. And needle mattress topper comes with responsive memory foam that provides pressure relief and better support.
Latex is another popular and good option, but the natural version can be quite expensive. Both natural and synthetic latex offers the support and comfort given by memory foam. The upside is that latex has perforations that make it cool enough for warm nights.
If you'd like a super soft foam go for a feather-filled topper and if you prefer more organic options, go for a topper made of wool.
The thickness of the mattress topper is another significant factor you must consider. A mattress topper that's too thin won't make much of a difference or solve your predicament. One that's too thick might make it challenging for you to get in and out of bed. The right mattress topper should be between two and four inches wide and purchased according to your needs.
Let's say your mattress is firm and in good standards, but you need some softness added to the surface, a 2-inch topper would be perfect. If your mattress is a bit worn out or has a short height and is too soft and you need more support and firmness, then a 4-inch topper is the way to go.
Don't confuse thickness with density. Density is all about the mass of the topper which adds to its support and durability. A high-density foam would be an extra firm one with longer durability - and vice versa.
Just like your mattress, a topper has similar sizes; twin, twin xl, full size, all the way to California king. The size you purchase depends on your mattress size. It's okay to buy similar mattress sizes, and the topper since the topper goes on top of it. If you get a smaller or larger topper, you may miss out on that edge support and easily fall off your bed.
While we firmly praise them, mattress toppers are not the solution to everything. If your mattress is worn out beyond help, consider getting a new one. A topper is only a good solution for mild mattress issues. That said, if you need a mattress topper, choose the right one for your needs and take into account any medical conditions or allergies that certain materials might aggravate. With all of this in mind, we hope our best mattress toppers buyers guide helps you decide on the best topper for you.
