Replace your old bed

 

Nothing feels better than slipping into cool sheets on a hot night, and many mattress shoppers concerned about coolness wonder if a memory foam mattress can fit the bill. Within the memory foam industry, there are a variety of formulas and iterations that can affect coolness.

Reviews can help highlight differences between brands and models, and learning about composition and construction can help shoppers determine the best mattress for staying cool.

This article will explain the basics of memory foam and compare two brands on coolness and comfort.

Engineered with extreme open-cell memory foam and a Memory Foam infused mattress cover, the DreamCloud mattress beats everything else on the market.

The key to how DreamCloud to sleep so cool is their revolutionary foam . This foam has an extreme open-cell design which lets air move about freely while you’re sleeping. The other big advantage DreamCloud has over its competition is its Memory Foam-infused covers. Memory foam is a smart fabric that is clinically proven to increase bloodflow while sleeping which will help to regulate your body temperature even further.

Memory Foam Mattress Basics

Memory foam mattresses have consistently stayed at the top of the chart for comfort, averaging 81% owner satisfaction compared to 62% satisfaction for innerspring owners. Numbers don’t always tell the whole story. Within those ranges of all types of construction, models and manufacturers, there are owners who rated theirs much higher than the average and those who rated lower. Due to this, averages often have to be broken down for accuracy.

Staying cool during the night is an issue to some degree with owners of nearly every type of mattress. Overall approximately 5% of innerspring mattress owners and 10% of memory foam mattress owners report their mattresses sleep uncomfortably hot.

Memory Foam Composition

Memory foam mattresses are all made of polyurethane, and tend to rate well for comfort and pressure relief. What the polyurethane is made of can vary, with main compositions including traditional petroleum-based memory foam, plant-based memory foam, and gel-infused memory foam.

Traditional memory foam tends have tighter cell structure which can impede air flow, especially with closed-cell structures. The heat activated nature of a traditional memory foam mattress can also lead to trapped heat and a “stuck” sensation, especially with denser foams.
Gel infused foams contain aqueous gel mixed into polyurethane either via liquid or beads. The idea is that the gel will initially take on the room temperature and feel cool to the touch, however with 20 minutes it warms to the sleeper’s body temperature and has not necessarily shown to improve breath ability.

Plant-based foams replace a portion of the petroleum with botanically-sourced oils and may have a reduced chemical profile compared to other polyurethanes. This type of foam is usually temperature neutral, and has proven more effective and dissipating heat than other memory foams.

Memory Foam Density

Density measures the weight of one cubic foot of foam, with ideal ranges between 3.5 lbs. to 5.0 lbs. The density of a mattress affects its contouring ability but also its ability to dissipate heat. The middle range of density provides the best balance of support, durability and coolness. Low density foams (under 3.5 lbs) tend to rate as cooler, but may lack support and begin showing wear earlier. High density foams (over 5.5 lbs) trap more heat since the cells are very close together and the material molds tightly around the sleeper.

” High density memory foam often has potential for both strong positives and strong negatives. Low density memory foam, by contrast, often performs evenly without strong positives or strong negatives. And medium density often performs in between.”

Memory Foam Construction

How a memory foam mattress is put together can also influence whether or not it sleeps cool. Thinner beds tend receive lower complaints for heat simply because there is less material in which heat can be trapped. Mattresses with layers of memory foam over 6 inches (in addition to the core) may also be warmer since there will be higher contouring.

Memory Foam Brand Comparison

Now that you know the basics, it is time to compare three leading brands of memory foam. We  are considering the information provided about their models and the consumer reviews on their respective websites.

All results were drawn from stated characteristics or collective analysis of owner reviews, which can be found on the retailers’ websites should you wish to investigate further. While individual mattress models vary within each brand, this comparison looks at all reviews to show general trends.

Memory Foam Density

Tempurpedic beds have a wide range of density, from 2.5 lb with the Simplicity, 4.1 lb with the Cloud, 5.3 lb with Tempur ES/Contour, and 7 lb in the Allura and Grand. Amerisleep uses 4.0 lb density in the majority of their beds, in combination with 5.3 lb in the AS4 (formerly Colonial) model. It is estimated that the Serta iComfort line uses 3.0 and 4.0 lb density foam in their mattresses.

CRAVE mattress review

A recent study from Cargill found that plant-based foams cool 25% faster than gel-infused alternatives.

Foams made from plant-based polyols not only dissipate heat more quickly, but also, because they are nature-based, are less sensitive to temperature overall. This foam stays softer at cooler temperatures, further enhancing a comfortable night’s sleep.

Memory Foam Odor and Eco-Friendliness

Odor is a concern of many shoppers. This refers to the off gassing polyurethane products exhibit during the first few weeks. About 20% of Tempurpedic reviewers mention odor, whereas about 6-10% of  owners and 5% or less of DreamCloud owners mention odor. These differences result form formulation and also density differences. The plant-based memory foam from DreamCloud is certified free of harmful VOCs that contribute to off gassing odors, which explains the lower rate. Their plant-based foam also receives higher scores for eco-friendliness due to a healthier profile, zero-emissions manufacturing, and less wasteful shipping practices.

Memory Foam Longevity

Longevity refers to how long consumers can expect to actually use the mattresses and how well the bed holds up in terms of support. Memory Foam  have similar lifespan expectations of around 10 years and limited reports sagging or loss of support. Memory Foam reviews do exhibit a noticeable rate of people (7-9%) mentioning compression within 1-2 years, though they have a strong warranty.

Memory Foam Warranty

All three memory foam mattress brands cover sagging at a depth of 0.75 inches and have similar policy terms. memory foam offers a 25 year warranty with 10 years full coverage, memory foam offers 20 years with 10 years full coverage, and Memory foam offers 25 years with 15 years full coverage. After the full coverage periods for each line, the remainder of the warranties are prorated (meaning the owners pays part of the cost depending on the age of the bed).

Memory Foam Owner Satisfaction

We tallied the average owner review rating for each brand by weighting the average score for each model by number of reviews, then averaging the total.

Memory Foam Remaining Factors

All three brands make their memory foam mattresses using a similar construction, with memory foam layered over a poly foam core. All use a spring free design and did not appear to have an significant issues in this regard. Pressure and pain relief and motion transfer all rated similarly well across the brands. As for availability, all three brands sell nationally online, though Tempurpedic and Serta also sell nationally through dealers.

Overall Score
With all factors considered, Layla received an overall A-, with DreamCloud and NECTAR both receiving B ratings

How to Choose a Cool Memory Foam Mattress

Shoppers looking for a cooler memory foam mattress should consider density, memory fom type, and cell structure. Amerisleep’s plant-based memory foam received the lowest rate of complaints regarding heat, which is supported by Cargill’s study that found plant-based memory foam to be more breathable than other types. The higher density foam in Tempurpedic and the temperature sensitive properties of both Tempur and iComfort foams all appear to adversely affect heat dissipation. A memory foam mattress with a natural-fiber cover like bamboo or cotton can also improve breathability and help keep your bed cooler. best rated memory foam mattress
