Casper and Leesa have established their own benchmarks in the mattress niche but there is a significant difference between the two. The most obvious is the price variation. Leesa is a high-end hybrid mattress that costs about twice the price of the all-foam Casper mattress. While Casper is made up of four layers, Leesa has three, resulting to 11 inches of thickness, which is an inch shorter than the Casper. Both mattresses have many positives and trying to decide which one would be the best for your individual needs can be overwhelming. This Casper vs Leesa review delves into the construction and features of each to help you make an informed decision before buying your new mattress.
Casper is a household name that has been features in many publications including the New York Times and Forbes and has received numerous accolades from business leaders. Founded in April 2014, the company expanded delivery beyond the US into Canada but the manufacturing is fully done in the United States. The Casper mattress provides exceptional softness and support and its open-cell construction ensures users sleep cool throughout the night.
Leesa was first launched in 2015 with the goal of improving mattress quality and lowering prices. The company wanted to eliminate pricey and usually useless fillers that conventional manufacturers add to their products. Today, Leesa is totally focused on designing one-size-fits all mattresses that meet the needs of most sleepers. In particular, the Leesa Hybrid with its coil and foam construction brings the best of both worlds, providing consistent edge to edge support while sleeping cool with the perfect hug and bounce.

Three-layer construction featuring 6’’ support layer, 1.5’’ memory foam and 1.5’’ premium foam.
Starting with the Casper mattress, it is 12 inches tall and has four layers of foam inside a polyester cover. The top-most layer is 1.5 inches thick of open-cell foam. This provides a decent bounce and helps to keep the bed cool. Underneath it is a 1.5-inch of memory foam that is responsible for pressure relief, enhancing contouring and compression support.
The third layer is also 1.5 inches thick and apart from supporting the top two layers, it supports your hips and shoulders, making the mattress a great choice for side sleepers. The bottom layer is made of up of 7 inches of high-density polyfoam, acting as the base support for the entire mattress.
Leesa takes a different approach to its construction. At the very top, it has 1.5 inches of Premium Foam, which is a proprietary type of developed by the company. This layer is highly breathable, conforming and bouncy. It is followed by another 1.5 inches of memory foam, otherwise known as the ‘recovery layer’, responsible for relieving pressure and contouring to a sleeper’s body.
Then there is the support core, primarily comprising of 1000+ individually wrapped pocket springs. 6 inches thick, it adjusts to different body types and provides unmatched edge support. The mattress also comes with a quilted polyester-lycra cover, which is breathable as well.
The big difference here is in the number of layers. The Leesa has four foam layers in addition to the innersprings. The Tempur-Pedic only has two. How does this affect comfort? Let’s find out.
Below is a breakdown of the factors that will impact your sleeping experience with these mattresses.
Firmness and support
How hard or soft a mattress is a key factor to how welcoming it is and we all have varying preferences. There is not a single mattress with a ‘universal firmness’ (a level that everyone loves) and understanding this can help you select a firmness level that is perfect for you.
Firmness is usually measured using a scale of 1-10, whereby 1 is the softest and 10 is the hardest foam. Of course, these two extremes are non-existent, with most the most common firmness levels ranging from 5 to 7.5.
The Casper mattress falls under medium-firm with a rating of 6.5, while the Leesa is just firmer with a score of 7.
Both mattresses have a reputation of sleeping cool. The Casper does so thanks to the open-cell foam that makes its top layer. This foam has tiny pores that let hot air escape so you can sleep cool and comfortable. And since the mattress is fairly firm and doesn’t experience too much sink, there is generally enough airflow around the body to help keep it cool.
For the Leesa, the proprietary top layer Premium Foam is specially designed to sleep cool. It feels bouncy too and with minimal sink, something that makes it not to trap excess heat when your weight is on it. Another crucial element is the cover, which is made from polyester-lycra fabric that is highly breathable.
The Leesa scores higher marks in this area than the Casper mattress. Leesa hardly experiences any movement at all and makes a great option for couples. The Casper is similarly good in motion isolation. The reason why the Leesa gets a slight advantage lies in the individually-pocketed coils in its base support layer. Given that the coils are independent of each other, the pressure on one is not transferred to the other. So if your partner moves on the bed at night, the motion is only felt on their side.
The Casper and Leesa are both made to be responsive. This means the foams in their comfort layers compress proportionally to the amount of weight that is applied. The Leesa Hybrid may be just a bit more responsive because it has coils that help with the bounce-back. Despite being an all-foam mattress, the Casper responds pretty fast too. Those who switch positions during the night won’t leave a sunken section behind when they do.
A responsive mattress contours well to the body and helps maintain spinal alignment. Both the Casper and Leesa are good in this regard, but the former tends to provide slightly greater contouring than the Leesa Hybrid.
Resilience and bounce
Resilience simply refers to the act of a mattress regaining its shape when weight or pressure is not being applied. To see your mattress resilience, you just need to sit on it for a short while and then get up. How soon does the spot you were resting on decompress back to its original state?
Comparing our two mattresses, the Leesa Hybrid has a very high level of resilience thanks to its latex-like foam. The Casper does respond quickly as well but because of a coil construction, the Hybrid feels bouncier than the all-foam Casper mattress.
Generally, beds that come in a box do not come with defined edges. As a result, you will experience a slight compression along the edges when you sit on either the Casper or Leesa mattress. Sleeping on the side of both mattresses should still feel secure. The Leesa, in particular, uses individually-wrapped pocket springs and premium foam technology to adapt to every curve of your body even if you are sleeping on the side.
Inflation time, off-gassing and smell
Expect some minor odor when you first set up any of these mattresses. The Casper should be set out for about a full day to expand to its original size and off-gas.
Leesa needs just an hour to fully expand to its ideal shape but will need a few days to become fully firm. Any odor will disappear within hours after the setup.

Average sleepers (130 lbs to 230 lbs)
Heavy sleepers (greater than 230 lbs)

The Casper is a favourite for stomach sleepers particularly for light and average persons, with heavy side sleepers loving it as well.
Leesa is a more rounded option, performing really well for side, back and stomach sleepers of average and heavy weights.
