8 Best Cooling Mattresses (Review) In 2021

Cooling mattresses are perfect for hot sleepers and are brilliantly cool to the touch helping everybody to rest throughout the night. With so many choices a cooling memory foam mattress or mattresses with innersprings, those we decided to review were cooling, good for hot sleepers, and made the Unclutterer team realize that there is so much more to a memory foam mattress than what we initially thought.

We chose some of the best cooling mattresses that we could, including memory foam and cooling gel mattresses, and those with inner coils. All of which have cooling elements for hot sleepers, and are great for those that simply want to avoid night sweats from body heat overnight.

If you sleep hot, are looking for the best cooling mattresses that suit you and your partner, and want a cooling bed that you can slide into every night after a hard day then we have a few tips for you.

Your temperature is changeable each and every night. It is a very important factor in physical, mental, and behavioral alterations during a 24-hour cycle. This is known as the circadian rhythm and it determines, also, when our body falls asleep to rest and recover.

Lowering the temperature in the room is a good idea and helps you to sleep, surprisingly enough, but if you still like to cocoon yourself under covers and blankets the room temperature may not make a great deal of difference. This is why designers use technology to develop how we can achieve cooling during the night in the actual bed. Cooling benefits include not waking up hot and sweaty by regulating the body temperature to a comfortable level.

Choosing an appropriate mattress to lay on can help hot sleepers, with sweating, and hot flashes. Below are some of the materials used in the best cooling mattresses available in the USA today.

Your budget, which position you sleep in, and how light or heavy you are will determine the type of firmness level you opt for in a new mattress. The firmness level determines how much a mattress is priced at, as well as how durable it is and how good it is at relieving pressure. You will find that latex, innerspring, memory foam, and hybrid mattresses are offered with multiple firmness options.

We all need relief from pressure points to help us sleep and need to have adequate support to alleviate the chance of a poor night of sleep. As a brief rule of thumb, the following might help when you go ahead and look at new mattresses.

A medium-firm mattress or one with a high firmness level is an ideal option if you are a lighter person or if you tend to sleep on your side. Some lighter people have said that a firm mattress doesn't offer the type of cradling or 'hugging' that they like for a comfortable sleep.

That said, some mattresses that are soft or medium lack the support that some of us need. Heavier people may find that their level of comfort is compromised with a soft or ultra-soft mattress.

A good thing to look out for is a mattress with dense layers that include latex or coil support layers that can counteract sagging over time. A good promise of strong edge support from the manufacturer also helps, especially if you sleep close to the edge, and this sturdy edge support will make it easier to get out of bed without the risk of it sagging underneath your bottom.

Despite the saying, size does matter - well in a mattress it does anyhow. Some beds are made with the heavier person in mind and some are designed for their specific cooling effects. For anyone with space and the budget, the larger the better. Not only is this because you have room to sleep comfortably without feeling the motion of your partner but allows less heat transfer between two people.

Six available mattress sizes are:

1. Twin 39" x 75"
2. Twin XL 39" x 80"
3. Full 54" x 75"
4. Queen and Split Queen 60" x 80"
5. King and Split King 76" x 80"
6. Californian (Cal) King and Split Cal King 72" x 84"

Longevity is perhaps the main thing most of us consider when looking at mattresses and a cooling mattress ideally should be worth the investment. Innerspring mattresses aren't perhaps going to be number one on your list as they can develop indentations over time.

The best thing to note is when you should replace your cooling mattress or any mattress for that matter. If you are waking up tired and irritable then it might be time for a change. Also, coils within a mattress can come loose in time and once you feel bumps, it's time for a replacement. When you are looking for a new cooling mattress, polyurethane can be the cheapest option but in the long run, this might be a compromise but if you can't quite stretch to a higher budget then look out for the mention of the density of the foam - the higher the density, the longer you can expect your new cooling mattress to last.

If you are the heavier person, a cooling mattress with reflex foam can be a good choice. This material has a good firmness level and therefore carries weight well so you can expect it to last longer than others.

Convoluted foam is often used as a mattress top surface but it isn't well known for being long lasting. They do add support for a short time and they are cheap as a temporary option but if you want it to last a bit longer then the mattress you choose should have a very supportive base layer.

• Phase changing materials

Where most material transports heat away from the body by keeping the surface of a mattress cool, phase-changing material actually carries it away then returns to a warmer temperature when things are cooler, carrying out this process throughout the night. This type of material is suitable for couples sleeping on one mattress where each individual sleeps at a different temperature.

• Cold wire protection

This material is expertly crafted for cooling comfort. Fibers are woven into the mattress fabric allowing them to help your body with its temperature level. It helps to remove moisture during sleep and works almost like phase-changing material, it just comes in the form of a fiber or yarn.

• Quilted and non-quilted

Non-quilted covers are best for hot sleepers as quilted materials are obviously thicker and contain more fabric - the increased surface area means more heat can be produced. For cooling benefits, avoid very-low-density memory foam which is usually included in quilted mattresses and mattress covers/toppers. Because non-quilted mattress covers are thinner they are less likely to generate more heat.

• Latex foam

If you sleep hot then latex foam is an excellent choice so check out the manufacturer's description. This type of material is aerated, not a good conductor of heat can be cool to the touch, and manages the airflow around the body making it ideal for use in a cooling mattress or topper. It bounces back quickly once you move around and some sufferers of back pain do choose this type of memory foam mattress.

• Gel-infused memory foam

Gel works like water does, keeps the things it touches cool. You may have seen or heard how gel works before. It typically absorbs heat and retains it. Again, like water, it has a particular temperature level though before the gel itself starts to heat up. It is a good material to use within a mattress and will help regulate the temperature to a certain level. You may also see other types of materials infused within mattress fabrics. These include graphite, copper-infused, gels, among others. Gel alone doesn't ensure that it will have maximum cooling benefits but can have a small impact.

• Other infused materials

If memory foam is permeated more completely with gels, coppers and graphite, it can have more of an impact than materials that are not entirely infused with these elements so the cooling performance of such a mattress is notable.

• Memory foam

This type of material has an elastic characteristic but for some, the 'hug type of feeling that memory foam offers doesn't help with body heat and can be uncomfortable. Memory foam can be slow to bounce back whereas poly foam responds faster and can be more comforting to those who sleep hot as the hug feeling isn't as forceful. Polyfoam is okay as a top layer in a mattress for back pain relief.

It's important to know the make up of an entire cooling mattress if you are a hot sleeper. Memory foam will not make up the entire mattress which is typically made up of two, sometimes three, layers. The different materials in each layer work together for cooling and heat performance by creating better airflow and a cooling surface. This is generally what you will find when looking at the best cooling mattress to suit you and/or your partner.

A good few examples might be a Saatva mattress which tops two layers of coils with a euro-style pillow top layer which usually contains only a little memory foam. Because the surface is thin there isn't much material to prevent aeration ensuring that the Saatva mattress is a good choice for its cooling elements. Another is the Purple - a cooling hybrid mattress best known for topping two layers of poly-foam with a gel elastic polymer. The 'grid' used in the polymer generates a good airflow and is the closest to the body ensuring heat is absorbed from the sleeper. The cover on the mattress should be thin enough that it doesn't stop the flow of air - as we mentioned earlier, a quilted cover is thicker and the increased surface area is able to lessen the heat.
