The 6 Best King-Size Mattress Toppers for Extra Comfort

Do you have a hard time sleeping at night? Is your mattress too firm, or is your partner keeping you awake? While it might be tempting to buy a new bed, if your current king-size mattress is less than 10 years old, a king-sized mattress topper may be a better and more affordable solution.

Couples generally prefer a king-size mattress because it gives them extra room to spread out and be more comfortable. But while you have more space, this still doesn't mean the mattress itself is ideal. Everyone has different sleep positions and needs different options for a mattress. A mattress topper is an excellent option for relieving pressure points when a mattress is too soft or firm. It's an additional removable layer of comfort and support, like adding an extra cushion to the mattress. It's called a topper because it's laid on top of the mattress. Toppers are a great option for changing the feel and comfort of a mattress without buying a new one. They also absorb a lot of the mattress's surface wear and tear and extend the life expectancy.

Mattress toppers come in a variety of different materials and types. Some even feature cooling aspects to help sleepers prevent overheating. Everyone will have different needs, and ultimately the best king-size mattress topper will be based on what type of sleeping position you use and your overall comfort level. We'll highlight our favorite picks for king-size mattress toppers and explain what makes them stand out.

While memory foam can make for a very comfortable mattress topper, it's not the best for keeping you cool at night as memory foam absorbs and trap body heat. The GhostBed Memory Foam Topper is a unique option because it has channels throughout the foam that allow the air to flow freely towards the surface. The foam is also infused with gel for added breathability, and the cover is made of the company's Ghost Ice Fabric, which is cool to the touch. 

The GhostBed Memory Foam Topper is an excellent topper for those wanting to extend the longevity of their mattress. It measures 3 inches thick, and the foam is divided into five different firmness zones. These five zones create more support around the middle of the body and a softer feel for lighter body areas. This keeps the body in neutral alignment and promotes a great night's rest. The cover is removable, waterproof, and machine washable, and GhostBed provides free shipping anywhere in the U.S. While the company does not allow returns, they offer a 5-year manufacturer's warranty.

Saatva Mattress Toppers

Saatva offers three mattress toppers to choose from, each made of a different material. All sleepers will find a topper that is ideal for their body type and sleep position. Their lowest price point topper is made of foam and has the firmest feel of the three. It is 1.5 inches thick and consists of a single high-density polyfoam that conforms closely to your body and improves overall alignment.

Next is graphite, which is the thickest option. It has a 3-inch profile and contains two layers. The top layer is memory foam infused with cooling graphite, and the base is high-density foam. It's a medium-soft feel, and many side sleepers find the topper exceptionally comfortable. The last is a balance of the other two and latex. It has a 1.5-inch profile, and the Talalay latex is ventilated with small holes to circulate air freely. This pushes air to the surface and keeps you cool, so this topper is an excellent option for hot sleepers.

All three feature a cover made of breathable organic cotton and feature elastic corner bands that keep the topper in place. Saatva offers a 45-night sleep trial and provides free shipping in the U.S.
