Key Comparisons

In this comparison, we look at two of the best online mattresses you can buy. Both Casper and Leesa are popular choices among direct-to-consumer mattress brands, offering great trial periods, customer reviews, and price points. However, there are unique characteristics that set each apart. Below, we explore common questions to help you decide which mattress is best for you.

What is each mattress made from?

The Casper and Leesa use several types of foams to create comfortable, supportive mattresses. While their comfort foam layers differ, each design incorporates memory foam for pressure relief and body-shaping contour.

Looking first at Casper, this mattress has four foam layers. The top layer is a responsive poly foam designed for instant relaxation and a sinking feel. Underneath this comfort layer is a layer of memory foam. While many companies use memory foam as a first layer, Casper puts it second to give sleepers pressure relief, without making the mattress "too-firm." The third layer is another poly foam, which acts as a transition between the top comfort layers and the dense base. Rounding out the Casper is a high-density support foam. This acts as a foundation for the mattress and makes the design more durable. Wrapping these layers is a polyester blend mattress cover. The top is a soft, dimpled white fabric, while the navy sides panels feature a sturdier fabric blend.

Next up is the Leesa. This mattress has three foam layers, but each is thicker than the Casper's layers. The first foam is unique to Leesa — an Avena foam that acts and feels like latex. (Note: The sleep expert site Sleepopolis believes Avena foam is more durable than latex foam). Below this comfort layer is a layer of memory foam. Similar to Casper, Leesa uses memory foam as a second layer to give sleepers a plush, bouncy feeling on first contact. Underneath the memory foam is the third layer of thick support foam. This layer provides deep compression support and makes the mattress sturdier. Covering these layers is a polyester/lycra fabric cover. Cut from one piece of fabric, the Leesa mattress cover is stretchy and nearly seamless. It features a unique gray and white stripe pattern that looks and feels fantastic.

How thick is each mattress?

Typically, a thicker mattress means more comfort and support. Yet this does not always apply to foam mattresses, as foam density matters more than thickness. Since both the Casper and Leesa are 10 inches thick, the overall feel depends on the materials used. We explain what this means for firmness and ideal sleeping positions further down.

Thickness (in.)

How much does each weigh?

Both the Casper and Leesa are compressed and shipped in boxes, making it easier for customers to move and set up the mattresses. However, the Casper is several pounds heavier than the Leesa. This means rotating and lifting the Leesa is easier, especially for solo sleepers who may not have help moving the mattress. In the chart below, you can see how both designs weigh in against each other and our overall average.

Will they stand the test of time?

Neither Casper nor Leesa has been on the market long enough to gauge longevity. That being said, Sleep Like the Dead created durability ratings for each design based on its materials. According to these ratings, a Casper mattress will last 7+ years, while a Leesa will last 6-6.5 years. Both mattresses come with a 10-year limited warranty, so you can contact the customer service teams if you come across a design issue before then.

Durability (1-7)

What type of sleeping position is each mattress suitable for?

Understanding your ideal sleeping position is an easy way to determine if a mattress is right for you. Side sleepers need a mattress that can take pressure off of shoulders and hips, while stomach sleepers require a soft surface that sinks. Back sleepers usually prefer a firmer mattress with lumbar support, and freestyle sleepers need a mattress that can adjust to movement. To determine which sleeping positions are best for Leesa and Casper, we looked at customer reviews and rankings from Sleep Like the Dead.

Overall, the Leesa offers more bounce while the Casper hugs sleepers. This is good news for average-size side sleepers (130-230 pounds), who needs varying levels of support and comfort. For this position, the Casper is rated "good" for average sleepers, "fair" for large sleepers (230+ pounds), and "good to fair" for small sleepers (<130 pounds). Since the Casper has thinner comfort layers, large side sleepers can sink too deep into the firm base layer. On the other hand, small and average side sleepers find a balance of pressure relief and hug. The Leesa is loved by average and larger side sleepers, with each giving a "good to fair" rating. Small side sleepers found the Leesa to be less comfortable, possibly due to the responsive comfort layer.

Without a doubt, back sleepers were most comfortable on both the Leesa and Casper. The Casper received a "good" rating for small, average, and large sleepers. However, the Leesa was not far behind, receiving a "good" ranking for average sleepers, and a "good to fair" rating for large and small sleepers.

Stomach sleepers had mixed feelings about the Casper and Leesa. Both mattresses were "good" for average-size sleepers. Yet Casper is "good" for small sleepers while Leesa is rated "fair." Large stomach sleepers prefer Leesa over Casper, likely because of the springy latex-like comfort layer.

Which one is firmest?

Besides sleeping position preference, firmness is a major factor in overall satisfaction. While Casper and Leesa are rated as a 6 out of 10 on Sleepopolis' firmness scale, the feels are slightly different. Leesa has a thicker comfort layer that acts like latex, so sleepers will immediately sink in, but then feel a rebound. Casper has a thinner comfort layer before the memory foam, so sleepers get a "hug" feeling and melt into the mattress.

FIrmness (1-7)

How much does each mattress cost?

The Casper is more expensive than Leesa for all sizes– and the difference increases as the size increases. While the price variation is nominal for a single mattress, it increase to almost $100 for a king-size mattress. Since the cost is similar, we recommend deciding based on firmness, sleeping position, and materials before price. However, know that Leesa donates a mattress to charities in need for every 10 mattresses sold.

Which has the highest customer ratings?

Customer satisfaction depends on a number of ratings, so we considered mattress data in addition to real customer reviews. While Casper and Leesa received similar ratings on Google, Amazon, and other review websites, there was a difference between industry experts. Sleep Like the Dead gave Casper an overall ranking of 80% to Leesa's 78%. However, Sleepopolis gave Leesa a 97% customer satisfaction rating to Casper's 86%. Remember, all reviews are subjective, and it's best to consider all information before making a decision.

Customer Satisfaction (1-5)

So, which is better?

Truthfully, no single mattress is right for every sleeper. Some people need more cushion, while others require firm support. Since Leesa and Casper are so similar in rankings, you should look to which mattress suits your sleeping needs. If you prefer sinking into your mattress, yet having a firmer feel, the Casper may be best for you. On the other hand, the Leesa is ideal for sleepers who like a little bounce, want to give back to the community, and prefer a medium firmness.
