Key Similarities:

  • Both the Casper and the Leesa are memory foam mattresses that score high in pressure relief, making them great choices for side sleepers. If you like innerspring or hybrid mattresses with a firmer feel, these beds may feel too soft to you.
  • Both the Leesa and the Casper mattresses are medium-firm, meaning they have a balanced feel of soft, yet still supportive. On the firmness scale, medium falls in the middle and hits that sweet spot of not too hard, and not too soft.
  • Both offer 10-year warranties and 100-night sleep trials.
  • There is some off-gassing with both mattresses because of the foams used. This is harmless, though, and dissipates quickly after unboxing.

Key Differences:

  • The Leesa features a cooling foam top layer, which helps keep you cool better than the Casper.
  • The Casper is slightly pricier than the Leesa in the Queen size.
  • The Casper’s namesake is its zoned support layer, while the Leesa boasts its own proprietary foam technology.

The Casper Mattress Highlights

  • The Casper Original started out in the mattress space early, and uses its universal feel to accommodate many types of sleepers. It’s quite a popular mattress!
  • While most all-foam beds run hot, the Casper works to promote airflow. 
  • Casper earned a 10 out of 10 score for responsiveness! This means it adapts to your movements quickly, making it easy to switch positions at night. That’s why the Casper is phenomenal for combination sleepers
  • The Casper team is constantly perfecting their product design based on feedback from customers. This is apparent in their newest addition: the Zoned Support system. This foam layer focuses on soft support under your hips and shoulders, and core support designed for pressure relief.
  • Casper also offers other models: the Casper Wave Hybrid and the Casper Nova Hybrid.

The Leesa Mattress Highlights

  • The Leesa Original’s foam layers and medium-firmness make it ideal for all sleeping positions because of its balanced feel and cooling properties.
  • The Leesa is the highest rated mattress on Mattress Advisor, but also has a happy (and well-rested) bunch of customers who rate it a 4.8/5.
  • Leesa is always looking for ways to improve their products. In fact, they recently launched an updated version of their mattress with new pressure-relieving foam that took many trials and tests to perfect. t. The best part is, they didn’t raise the price of the mattress, so you’re still getting a quality mattress at a really great price point. You can watch our video below to see the highlights but as a quick teaser: it’s even better than it was before for side sleepers!
  • Leesa has a number of other models, like the Leesa Studio, Leesa Legend, and the Leesa Hybrid.

Compare the Inside Layers

To understand the differences in feel between the two mattresses, take a look at the Casper and Leesa’s mattress construction. We’ll take a deeper dive into how the two designs stack up, though they’re both similar in terms of comfortability and support.

The Casper features three soft memory foam layers designed for optimal support and comfort. The zoned support layer is the reason the Casper excels in spine alignment; this layer provides targeted support and relieves pressure points. Similarly, the Leesa features three memory foam layers, but its layers are encased in a soft cover. The Leesa’s foam layers offer body contouring for pressure relief, while also responding to your movements. The third layer of the Leesa features support foam and  gives the bed its phenomenal durability.

The main difference in their construction is the Leesa’s enhanced cooling features. The Leesa’s foam layers are made for airflow, and keep you cool better than the Casper does. Both mattresses feel soft and spring because of their medium firmness level, and are able to provide some of the best support and pressure relief you’ll find among memory foam beds. Both beds can also support sleepers of many different body weights and types.

Inside the Casper mattress

Inside the Casper

Casper is made up of three foam blend layers to offer breathability, pressure relief, and a springy yet contouring surface.

  • Open-cell Foam: Composed of Airscape breathable foam to enhance airflow
  • Zoned Support Layer: Comfort layer that uses 3 ergonomic zones to provide targeted support for maintaining spine alignment. Evenly distributes weight by giving softer support under hips and shoulders and firmer support for hips and lower back.
  • Durable Support Foam: Base layer that adds structure and durability to the mattress by preventing sinkage and reinforcing full-body support.

Let’s take a closer look at some of the factors that stood out during testing.

Responsiveness:

Responsiveness measures how well and how quick a mattress adapts to your movements. Both the Leesa and the Casper knocked it out of the park on this one, though the Casper beat out the Leesa just a smidge with a perfect 10 out of 10. Combination sleepers would enjoy either of these beds.

Spine Alignment:

Spine alignment is important for keeping a healthy back and healthy posture. Both the Leesa and Casper impressed our testers with their excellent spine alignment; whichever bed you choose, your back will stay nice and straight throughout the night!

Pressure Relief:

Pressure relief keeps undue weight off of your hips and shoulders, key areas that collect the most pressure when laying on your side.

The Casper and Leesa both nailed pressure relief; they received identical high scores of 8.5, and are both great picks for side sleepers.

All in all, these beds scored similarly on most factors. The main difference between the 2 is in their cooling ability. Both mattresses also offer superior edge support and motion isolation.

Summary

Between the Casper and Leesa memory foam mattresses, you can’t go wrong with either because of their universality. Still undecided? The Casper is great for those who want a reliable memory foam bed with durable support. If you’re more of a hot sleeper, go with the Leesa for your new mattress.

No single mattress is perfect for everyone. What works for some may not for others. Like if you enjoy the firmer feel of innerspring beds, the Leesa and Casper may be too soft to you. So we can’t give a definitive answer of which mattress is best when you compare Casper vs Leesa. But we can help give you some guidance on your buying journey to help you become one step closer to a better night’s rest.

In our testing, Casper and Leesa scored pretty similarly, and looking at factors like materials, pricing, and sizes also leads you to see a lot of similarities. But overall, we can’t ignore that the Leesa is the highest rated mattress on Mattress Advisor. Plus, their fan base is pretty happy and well-rested too with a customer rating of 4.8/5. Positive customer reviews are always reassuring when purchasing online. Plus, between the coupon codes and affordable standard prices, you can score either of these mattresses for fairly cheap!

Both Casper and Leesa put a ton of work behind their design and are constantly working to innovate their products to help more people get a better night’s sleep. Trust us when we say that you’ll be happy no matter which you choose.
