The all-foam Nectar Premier Copper Mattress features a poly-nylon cover with copper infusions. Its comfort system is composed primarily of a 4-inch thick memory foam layer. The memory foam is infused with gel and contains phase change material designed to regulate temperature by pulling heat away from the bed’s surface. A 1-inch layer of polyfoam serves as a transition to the support core.

Compared to other all-foam mattresses, the Nectar Premier Copper offers decent ease of movement. With its medium firm (6) rating, the bed prevents sleepers from sinking too far into the mattress’ surface. The thick layer of memory foam absorbs a good deal of motion transfer, so couples are less likely to disturb each other at night.

With its 14-inch profile, the mattress is thicker than average. Its contouring foam excels at relieving the pressure that builds up in the hips and shoulders for side sleepers. The mattress also provides adequate support for back sleepers who weigh less than 230 pounds.

What Do Hot Sleepers Need for a Good Night’s Sleep?

Finding the perfect sleep temperature involves multiple factors, from your mattress to your bedding and bedroom temperature. We’ll walk through all the considerations to help you optimize your mattress and bedroom for a cooler night.

Find the Type of Mattress That Helps You Sleep Cool

The materials used to construct a mattress, including the comfort layers, cover, and support core, all contribute to how well it regulates temperature. Your sleeping position and body type may also play a small role in whether you find that a mattress sleeps hot or cool. When choosing a mattress, consider what materials it’s made of and how far it lets you sink in, potentially trapping heat around the body.

What Makes a Bed Sleep Cool?

Some mattresses naturally have more open space for heat to dissipate. Other mattresses attempt to regulate temperature by adding cut-outs or perforations to solid layers. Still others utilize materials such as gel infusions, phase change material, or other elements designed to actively pull heat away from the surface of the bed.

Build a Cooler Sleeping Environment

In addition to a cooling mattress, there are many ways to optimize temperature for sleep. You may want to try incorporating breathable materials such as cotton and linen into your bedding. Hot sleepers may want to stay away from heat-trapping sources such as memory foam pillows, and use a fan or air conditioning in warmer climates.

Best Cooling Mattress Types

The best cooling mattress should dissipate heat away from the sleeper. Mattresses can accomplish this using either breathable designs or cooling technology.

Foam Mattresses

Memory foam and polyfoam can be used in the comfort or support layers of a mattress. Synthetic foams have a tendency to trap heat, although many manufacturers add technology such as gel infusions or use open-cell designs to reduce heat retention.

Why Does Memory Foam Get Hot? The Downside of a Close Hug

Memory foam is known for its close conforming. While this is ideal for relieving pressure, it leaves less room for heat to dissipate. The greater the surface contact with the body, the more heat the bed absorbs.

Foam Density, Heat Retention, and Sleeping Hot

Denser polyfoam and memory foam are often seen as more desirable, because they tend to last longer than low-density foams. However, denser foams are also more likely to trap heat, as they don’t have as much space between cells. Hot sleepers may want to seek out mattresses made with low-density foams, or opt for a hybrid design with room for heat to escape through the support core.

Hybrid Mattresses

Hybrid mattresses generally offer more breathability than their all-foam counterparts. Because hybrid mattresses combine foam, gel, or latex with a layer of innersprings, they provide room for airflow that helps mitigate any heat retention from the upper layers. Certain hybrids may sleep hotter than others depending on the firmness and the materials used in the comfort section.

Latex Mattresses

Although they don’t have the open design of coils, latex mattresses generally sleep cooler than polyfoam or memory foam mattresses. Natural latex is relatively breathable, and it doesn’t conform as closely to the sleeper, so it doesn’t trap as much heat around the body. Many companies also use perforated latex to allow more room for heat to escape.

Airbeds

The ability of an airbed to regulate temperature depends largely on its comfort layers. Airbeds made with memory foam may trap heat, whereas those made with latex may sleep cooler. The air chambers themselves generally retain minimal heat.

Cooling Mattress Materials

Mattress manufacturers use a variety of cooling technologies designed to keep sleepers cool.

Coils and Springs

Coils and springs are mostly empty space, which allows for airflow and encourages heat to escape the mattress. Innerspring mattresses with minimal comfort sections tend to sleep the coolest. Hybrid mattresses combine springs with layers of foam or latex, which can add benefits like pressure relief while still maintaining a more neutral temperature compared to an all-foam mattress.

Gel-Infused Foam

Memory foam and polyfoam mattresses often incorporate gel infusions intended to help them sleep cooler. The gel is designed to absorb and release body heat instead of allowing it to stay in the mattress.

Copper-Infused Foam

Copper has a reputation for its ability to conduct heat. Manufacturers may include copper infusions in a mattress with the intention of drawing heat away from the surface.

Natural Latex

Natural latex is very breathable, and it doesn’t tend to conform as closely, meaning sleepers make less contact with the surface of the mattress. Additionally, latex may contain tiny pinholes that allow heat to escape.

Celliant Fiber

Celliant is a proprietary material designed to convert body heat into infrared energy. This is said to reduce moisture buildup and help moderate temperature.

Less Sweat and More Shut-Eye: Creating an Ideal Sleeping Environment

Sleeping in a hot room can be difficult. If you’re finding it impossible to sleep soundly during warm summer nights, you may find it helpful to make changes to your bedding or invest in a fan or air conditioning. While these solutions should help keep most hot sleepers cool, they may not be sufficient if your mattress traps an excessive amount of heat.

Find the Right Temperature for a Cool Night’s Sleep

Many people find that the ideal temperature for sleeping is around 65 to 70 degrees Fahrenheit, although this is subjective. Those who sleep hot may wish to set the temperature lower. Experiment to see what temperature works for you.

You can keep the room cooler by closing the shades during the day and opening windows in the evening. A bedroom fan or air conditioning may also be helpful.

Look for Breathable Sheets

Some materials inherently retain heat more than others. For example, flannel and fleece are perfect for many sleepers on a chilly winter’s evening, whereas lightweight materials like linen breathe better.

Most materials are somewhat versatile depending on their density and weave. For example, cotton with a lower thread count tends to be more breathable. Polyester can also take on different qualities depending on how it is made. Although wool is best known as a winter material, it also excels at wicking moisture to prevent sweat from building up.

Cooler Sheet Types:

  • Linen
  • Tencel
  • Cotton with a percale weave

Hotter Sheet Types:

  • Cotton with a sateen weave
  • Flannel
  • Fleece

Don’t Weigh Yourself Down with Heavy Blankets

Many people find they sleep easier using a blanket, but this may be difficult to reconcile with a hot climate. For hot sleepers, it’s important to seek out materials that allow heat and moisture to escape the bed. Wool is a good option, as it stays dry and generally maintains a neutral temperature. As a general rule, lightweight materials tend to trap less heat.

Swap Out Your Old Pillow With a Cooling Pillow

Whereas polyester or memory foam pillows may retain heat, cooling pillows are built with breathable components designed to reduce overheating. Some options include buckwheat, kapok fibers, or some natural latex models. It’s also important to choose a breathable pillowcase.

If Your Bed’s Too Hot, Try a Cooling Mattress Topper

For hot sleepers who aren’t ready to invest in a new mattress, a cooling mattress topper may offer a solution. Usually between 2 and 4 inches thick and made of gel memory foam, latex, or wool, a cooling mattress topper adds an extra breathable layer next to the sleeper. Some mattress toppers may also incorporate cooling technology such as phase change material.

Keep in mind that some mattress toppers may worsen overheating problems. For instance, regular memory foam toppers are likely to display the heat retention typical of memory foam. As you would when choosing a mattress, be sure to look for materials known for their cooling abilities.
