Emma is a mattress manufacturer based in Germany that focuses on making quality products at affordable price-points. The company was formed in 2015 and has since expanded to sell its products directly to consumers in more than 30 countries. In addition to mattresses, Emma also makes bed bases and foundations, pillows, and mattress protectors. 

The company’s flagship mattress is the Emma Original, an all-foam model with a medium firm (6) feel. The CliMax Hybrid is currently the only other mattress in the company’s product line. It’s also medium firm, though it’s designed with couples in mind and aims to be one of the best mattresses for sex. It’s also intended to provide both pressure relief and support for sleepers with bigger bodies.

We’ll take a close look at how the CliMax Hybrid performed in our sleep lab tests, examining areas like edge support, ease of movement, temperature control, and motion isolation. In addition, we’ll provide recommendations on who will enjoy this mattress most, taking sleeping position and body type into consideration.

Mattress Performance

Motion Isolation

This model allows more motion to transfer than all-foam mattresses typically do, but it’s within the average range for a hybrid model. The memory foam and polyfoam layers absorb motion effectively, but the mattress still feels fairly responsive because of the coil support core.  

People who wake easily from their partner’s movements may want to consider a hybrid with more memory foam or one with a thicker comfort system. Exceptionally light sleepers or those who want top-notch motion isolation will likely prefer the Emma Original, which is an all-foam model.

Pressure Relief

The CliMax Hybrid offers sleepers very good pressure relief, thanks to its foam comfort system and zoned support. The bed’s comfort system contours sleepers’ bodies, absorbing impact beneath the hips, shoulders, and joints.

The memory foam layer has five zones that provide strategic support designed to keep the spine evenly aligned. This zoned combination helps prevent pressure point buildup without sacrificing support.

Temperature Control

Despite its cooling-specific features and hybrid design, this model lacks the temperature control needed by the hottest sleepers. People in moderate climates and those who don’t tend to overheat in bed should find this model’s average temperature control sufficient, but it may not be cool enough for all sleepers. 

The Emma CliMax has shorter coils than many other hybrids, leaving less room for air to circulate. Air does move freely through these mini-coils, but heat can become trapped in the foam layers that rest above and beneath the coiled support layer. 

Our testers found that the open-cell polyfoam topping the mattress helps dissipate heat, but the dense memory foam and base foam layers retain warmth. Shoppers seeking exceptional temperature control may want to look for a hybrid that has a thicker coil support core or gel-infused foams.

Edge Support

Polyfoam rails wrap this mattress’ perimeter, increasing its edge support. However, its thick foam comfort system compresses deeply with direct pressure application, resulting in average overall edge support. 

Our testing team noticed that the perimeter sagged slightly when they sat on the bed’s edge. People who don’t have a hard time getting in and out of bed shouldn’t have any issues with the CliMax Hybrid, as its combination of mini-coils and perimeter reinforcement provides enough structure for most people.

A mattress with coil reinforcement instead of foam reinforcement may be a better option for sleepers who need maximum edge support.

Ease of Movement

This model’s combination of mini-coils and foam allow for reasonably easy movement atop the mattress, though it’s not responsive enough for sleepers who prefer a traditionally bouncy feel.

The coil support core has a resilient feel, but at 4.7 inches, the coils aren’t as tall as they are in many other hybrids. As a result, the bed is less responsive than some of its competitors, and our testers found that the foam comfort layers slightly inhibited movement.


The best mattresses for sex generally excel at ease of movement, temperature control, and edge support. While the Emma CliMax performs adequately in these areas, our testers judged its chief strength to be its pressure-relieving foam comfort system.

This makes the CliMax a good choice for couples who like more cushioning during sex, though people who prefer greater bounce may want to consider a model with a thicker coil layer.


Off-gassing is a term for the chemical-like odor that results when volatile organic compounds (VOCs) are released after unboxing products made with foam materials.

The Emma CliMax Hybrid has modest off-gassing due to its moderately thick foam layers. Though off-gassing is considered harmless, people who have respiratory issues and those sensitive to odors should unroll their mattress in a well-ventilated room.

Side Sleepers

The Emma CliMax Hybrid has the attention to pressure relief and spinal alignment that side sleepers generally prefer. In particular, our testers between 130 and 230 pounds found this model provided excellent comfort and support. Its foam comfort system contours the body, providing plenty of cushioning for the hips and shoulders, which are areas that can get sore for side sleepers. 

The zoned memory foam layer contains five distinct areas to enhance pressure relief by providing multiple support levels. Increased pushback beneath the hips, shoulders, and head helps ensure that the spine rests on an even plane and the midsection doesn’t sink too far into the mattress’ core. 

This model’s medium firm (6) feel was a bit too firm for our side sleepers under 130 pounds, who generally prefer a plusher model, while some testers over 230 pounds said they prefer slightly stronger support.

Back Sleepers

Overall, the back sleepers on our product testing team found this model a comfortable and supportive option. Its pressure-relieving foam comfort system, zoned support, and mini-coil support core combine to create a medium firm (6) feel that’s suitable for back sleepers of all weights and body types. However, back sleepers under 130 pounds offered the most praise during our sleep trials. 

Back sleepers tend to like mattresses that equally prioritize cushioning and spinal support, which this model does well. Its memory foam comfort layer cradles the lower back, while the zoned support system prevents sleepers from feeling as if they’re being absorbed by the mattress. The pocketed mini-coil layer and the high-density polyfoam base work together to create a strong structure that keeps back sleepers’ spines on an even plane.

Stomach Sleepers

Stomach sleepers generally need a mattress with robust support so that their spine doesn’t curve while sleeping. This mattress is a comfortable option for stomach sleepers who enjoy a softer feel, but our testers over 230 pounds felt that they sank too deeply into the comfort system.

The CliMax Hybrid offers adequate support for stomach sleepers who weigh under 230 pounds, but stomach sleepers over this weight range will likely prefer a firmer model.

Emma CliMax Hybrid Mattress Review Breakdown

The Emma CliMax Hybrid Mattress uses foam and mini-coils to create a medium firm (6) surface that balances pressure relief and support. 

Featuring an 11.5-inch profile, the construction of this hybrid mattress begins with a layer of proprietary polyfoam. It has an open-cell structure that’s designed to promote airflow and decrease heat retention. The comfort system continues with a memory foam layer that enhances pressure relief by adapting to the body’s shape. 

Five different zones within the memory foam layer increase and decrease support levels according to where most sleepers need it, with greater support beneath the hip and shoulder areas. This feature helps keep the spine on an even plane while relieving pressure. 

The mini-coil support core is 4.7 inches tall, which is a bit shorter than most hybrids. The coils are wrapped individually and move independently from one another, helping to decrease overall motion transfer. Air easily moves between the coils to keep the mattress fairly cool. Foam rails wrap the bed’s perimeter, increasing edge support. 

Beneath the coils is a foam layer that acts as a strong foundation to anchor the mattress and absorb impact. The mattress has a removable and machine-washable cover made from soft polyester that’s engineered to disperse heat and wick moisture.

Mattress Prices and Sizing

The CliMax Hybrid Mattress has a competitive price-point that value seekers will likely appreciate. It’s within the average price range for a high-quality hybrid mattress, and it’s more affordable than many other comparable models.
