Emma and Casper are two of the most recognizable brands behind some of the best mattresses in a box. The Emma Hybrid Comfort and Casper Original Hybrid are both excellent options if you’re looking for a mattress that combines the comfort of a foam mattress alongside the additional support of coils. But although these mattresses look similar on the surface, they’re built quite differently. In this Emma vs Casper comparison piece, we’ll explore their differences and similarities.
Like many of our best mattress selections, both the Emma and the Casper mattresses are hybrids, and both brands provide decent sleep trials and warranties. However, each has its own distinctive design and sleep feel.
There’s also a considerable price difference between them. At full MSRP, the Emma Hybrid Comfort is $1,199 for a queen, but a 50% off sale means you can currently buy a queen size Emma Hybrid Comfort for $599 from Emma Sleep. The Casper Original Hybrid is more expensive, with a queen costing $1,495 at MSRP, although you can currently buy a queen size Casper Original Hybrid for $1,270 from Casper. Is the Casper worth the higher price tag? Let’s find out in this Emma vs Casper comparison.

Emma vs Casper: Materials & design
- Both mattresses are hybrid models
- The Emma Hybrid Comfort is 13” and has seven layers
- The Casper Original Hybrid is 11” and has four layers
Like many of our best hybrid mattress entries, the Emma Hybrid Comfort and Casper Original Hybrid are both made up of a combination of foams and coils. But, as you might expect, the fundamental design differs from mattress to mattress.
Underneath the breathable and moisture-wicking cover of the Emma Hybrid Comfort is a layer of Emma’s proprietary Point Elastic Airgocell foam that is designed to absorb and release excess body heat. Up next is a cool memory foam layer to mold to the body, followed by durable HRX foam. This sits on top of the seven-zoned edge-to-edge pocket springs, which are individually wrapped to encourage airflow. The springs are designed to adapt to each sleeper’s spine, for optimal support and spinal alignment. The whole mattress sits on a stabilizing base and an anti-slip lower cover with handles.
The Casper Original Hybrid starts with a cozy knit cover with added edge support, followed by a layer of Casper’s signature foam with AirScape technology, designed to increase airflow. Underneath this is a layer of memory foam divided into three ergonomic zones designed to support and keep the spine aligned. Last up is the layer of springs to add lift and support to the mattress. The perimeter of this layer is also firmer to provide further edge support.
Emma vs Casper materials & design winner: Emma
Although both mattresses are well constructed, we think the Emma is slightly superior, with more layers of foam for contouring and support alongside the seven-zoned pocket springs.
Emma vs Casper: Comfort & support
- The Emma Hybrid Comfort is a medium firm mattress
- Emma’s official rating is 5/10 but customers suggest it’s closer to a 7-7.5/10
- The Casper is also a medium firm mattress, rated at 6.5/10 for firmness
Although Emma rates the Hybrid Comfort as a 5/10 for firmness, customers report that it sleeps more like a 7-7.5/10. This make is particularly suitable for back sleepers, with the seven-zoned spring layer doing a great job of easing aches and pains. The foams in the Hybrid Comfort are also a little firmer than some mattresses and, while there’s great pressure relief around the hips and shoulders for back and stomach sleepers, we think that many side sleepers (and lightweight side sleepers in particular) are likely to find this mattress too firm.
The Casper also sleeps slightly firmer, boasting great mattress isolation. The three-zoned layer of memory foam offers targeted support, with softer support at the shoulders and firmer around the hips and lower back to keep the spine aligned. Consequently, the mattress does a superb job of keeping you comfortable whatever position you sleep in, with targeted cushioning along the pressure points. However, heavier sleepers may not find it firm enough.
Emma vs Casper comfort & support winner: Casper
Although both mattresses offer great support, we think that the targeted support of the Casper edges it here. It suits a wider range of sleeping styles and keeps sleepers comfortable and supported in key areas.
Emma vs Casper: Temperature regulation
- The Emma has two layers of cooling foam, coils and a breathable cover
- The Casper has a knit cover and ventilated foam to aid airflow
- Both mattresses do a good job of regulating temperature
The Emma Hybrid Comfort starts with a breathable cover to wick away moisture. Underneath this is Emma’s proprietary Airgocell foam, designed to absorb and release excess body heat, followed by a layer of cool memory foam. Well-spaced coils also help to promote airflow through the mattress.
The Casper Original Hybrid also has a breathable knit cover, as well as their signature foam help aid ventilation, promote airflow and dispel heat. Like the Emma, the coil layer also promotes airflow, with plenty of space between the coils.
These features on both mattresses should help to keep the average sleeper cool at night but, if you’re a particularly hot sleeper, you will probably want to consider one of our best cooling mattresses as these have features specifically designed to prevent overheating at night.
Emma vs Casper temperature regulation winner: It’s a draw
While neither of these mattresses are specifically designed for cooling, they both do a good job of keeping sleepers cool at night. With foam specifically designed to provide cooling, along with well-spaced coils, both these mattresses will keep the average sleeper cool while they sleep.
Emma vs Casper: Which should you buy?
Buy the Emma if...
✅ You sleep on your back or stomach: The slightly firmer feel of the mattress means that it's particularly supportive for those that sleep on their back or stomach. Emma's supportive HRX foam combined with a 7-zone ergonomic layer of pocket springs prevents the mattress from dipping or hollowing under pressure areas.
✅ You want a firmer mattress: The Emma Hybrid Comfort is a firmer mattress that you sleep ‘on’ rather than sinking into. There’s still contouring around the hips and shoulders, but the mattress is more responsive and easier to move around on and change sleeping position.
✅ You sleep hot: This mattress has plenty of features to help keep you cool, including a breathable top cover, Emma's Airgocell foam to absorb and release excess body heat and moisture, a cool foam layer and pocket springs that promote airflow.
Buy the Casper if...
✅ You want a mattress to suit all sleeping positions: With its clever three-zoned support foam, the Casper provides both soft and firm support where needed, helping to keep the spine aligned and pressure points supported in all positions.
✅ You want the option to upgrade: Although the Casper does a good job of keeping sleepers cool, there is the option to upgrade to Casper’s Snow Hybrid, which offer five degrees more cooling.
✅ You want superior edge support: The Casper’s reinforced edge provides an extremely stable surface, meaning sleepers can use the full width of the bed at night and sit on the bed without sliding off.
