Leesa Mattress Review 2024

Memory foam is a favorite amongst mattress owners from all over the world, especially because it provides good body support and contouring. But, as with every other type of product, memory foam mattresses have their own advantages and disadvantages and it would be useful for you to know a little bit of both before adventuring on your next shopping spree. The Leesa Mattress is one of the best there is and in this Leesa Mattress review we’ll go over all the reasons why that is.

Visco elastic memory foam isn’t that much different from regular memory foam. It is manufactured differently from one brand to another, which could eventually lead to the foam being more resilient in some cases. Visco foam is known for being solid and dense, which means that it acts like a barrier for most substances. Thanks to its elastic properties, it should be able to return to its initial shape after a short duration of time. This particular foam category is about 50 years old and was originally developed by NASA to make sure that their astronauts have a more comfortable launch.

Basically, memory foam is made from polyurethane, a material that’s commonly used in the construction of mattress, sofas or car seats. Due to tis high density, it has become popular for the support it offers, and a lot of mattress manufacturers prefer to use it because it has a longer lifespan compared to mattresses that have innersprings.

Open cell memory foam is just your average foam, but built with a different inside structure. The technology used to create it allows for better airflow inside the mattress, which makes it highly breathable.

Gel memory foam is (obviously) nothing else than foam infused with gel. Mattresses that use gel memory foam are also highly-breathable, but they do have one extra characteristic. They benefit from what the industry calls “phase-changing material”, which means that in different stages of your sleep, it’s capable of absorbing and releasing heat.

Leesa is a mattress brand with quite the tradition. Co-founded by David Wolfe and Jamie Diamonstein, Leesa takes a lot of pride in its financial success and donates a mattress for every 10 sold, leading to a figure of over 30,000 donated up to this date. Their company culture is invested in designing the best possible mattress to feel like you’re resting in a warm and endless embrace at the end of a long day. Without further ado, let’s see what the Leesa mattress has to over in terms of firmness, support and construction.

The Leesa mattress is all about the comfort and support provided by its 3 different foam layers. It all starts with a 2 inch layer of Avena foam. What makes this layer stand out of the crowd is the high level of breathability that it offers. If you’ve never struggled with waking up in the middle of the night and feeling sweaty and sticky, with the sheets virtually glued to your skin, then you won’t be able to appreciate the importance of having a mattress that allows proper air circulation by withdrawing heat from its surface and leading it away from your body. Avena foam has been around for almost 20 years and it’s known for the good support-to-coolness ratio that it provides. What’s really impressive about this layer is its bounciness. It almost feels like you’re lying on top of a latex mattress.

Avena claims that its memory foam is even more durable than latex (which we already know is one of the most durable materials used in the construction of mattresses). The 2 inch layer of memory foam that lies beneath the Avena acts as a very good support and prevents you from sinking into the mattress too much. By applying pressure to this comfort layer, you can feel its responsiveness and the contour it provides because of its memory foam construction. The Avena layer and the memory foam layer work hand in hand to provide a high number of sleepers with a bouncy mattress that’s able to comfortable take the shape of their bodies. Even with its firmness, it might appeal to a lot of side sleepers because of the support it provides. Last, but not least, comes the 4 inch layer of support foam, acting as a base for the mattress.

Leesa has created a little something called Universal Adaptive Feel. It’s a term used to describe the results given by the 2 top layers of the mattress. By working together, these layers are capable of supporting a wide array of body shapes and sleeping styles. What’s so amazing about this combination is that Leesa has manage to counteract the quality of the memory foam that makes the body sink into the mattress with the bounciness of the top layer which, as we mentioned, feels a lot like latex.

How comfortable you are going to feel when sleeping on a mattress is greatly determined by its firmness level. No everyone enjoys sleeping on a firm mattress, just like some don’t find plush mattresses very comfortable. It’s all about what your body needs: the setup that it requires to find comfort at the end of the day. Describing the firmness of a product is pretty hard if you didn’t have the chance to test the mattress yourself. People with different weights and body shapes will feel the same level of firmness in a different way. When you first get the chance to sit down on the Leesa mattress, it will feel medium. Testing the firmness of the mattress can be done by standing on top of it and then measuring how much the mattress sinks in. On a scale from 1 to 10, 10 being the highest level of firmness, the Leesa mattress is somewhere in between 5.5 and 6.5.

We want to discuss about the indentation load deflection of the different layers, but let’s explain the concept first. Indentation load deflection (or ILD, for short) is a term generally associated with foam mattresses. It measures the softness or firmness of the memory foam. The regular formula calculates how many pounds it takes for a memory foam piece measuring 4 inches in thickness to sink in by 25%, based on a test that applies this weight on an area of 50 inches. This weight is also referred to as the amount of pressure in this test, which is a number that eventually reflects the indentation load deflection.

ILD is sometimes expresses as a range, not as a single number. This happens because the rating can depend on the reconditioning of the memory foam prior to the test. In addition to that, there are other variable that can lead to variations of the ILD, such as humidity. For example, if the ILD of a mattress is 10, it means that it takes 10 pounds of weight to sink the mattress in to a 25%.

That being said, the Leesa mattress has a different ILD rating for each layer. As a general note, an ILD rating of 12 is the correspondent of a very plush mattress, while an ILD of 50 shows a very firm one. The Avena foam layer has a rating of 20, the memory foam layer has a rating of 9, while the base layer has a rating of 32. Calculating the average of these 3 numbers, you get a medium-firm mattress.

The Leesa mattress was clearly constructed in an intelligent manner, as the most breathable layer within a mattress should always be placed on top. Dissecting the mattress, you could see the indentations on the lower side of this layer, almost resembling those of an egg carton. The airholes on the top side of the mattress are designed to help air circulate downwards, to the large aeration holes we mentioned earlier. To better understand why the Leesa mattress provides great breathability levels, you should know what happens to your body’s temperature when you lie in bed.

The minute you start dozing off, there is a slight drop in your body’s temperature. An unsuitable mattress will trap your body’s heat and prevent it from undergoing the normal temperature stages of sleeping. In general, memory foam is known for retaining heat, but Leesa is quite different in that aspect. It usually takes about 15 minutes for the Leesa mattress to return to the room’s temperature after you get up. This is longer than average, but still a very good score considering that it features a memory foam layer.

If you’ve ever shopped for a new mattress, then you’re probably already familiar with the concept of edge support. This depict the capabilities of the mattress to stay firm as you apply pressure on its edges. If you often find yourself sitting on the edge of the bed for whatever reason, you need it to stay firm, for your own comfort. Edge support is also important for getting out of bed, as it would be terrible to find yourself slipping off the bed. The Leesa mattress doesn’t have the best edge support we’ve ever seen in a foam mattress, as it sinks in quite a bit when you sit on the edge of the bed. However, this is not uncommon for memory foam mattresses. But even with this little bit of sinkage, the bounciness of the Avena layer makes it easy to get out of bed. It’s important to mention that even if it doesn’t provide the best edge support, if you find yourself sleeping to close to the edge of the bed, you shouldn’t feel like you’re sliding off.

There once was a commercial, back in the days when memory foam mattresses just started appearing on the market. The commercial depicted a woman that was jumping up and down on a bed, with a glass of wine placed next to her that didn’t move a single inch. It was particularly impressive at the time, because it depicted amazing motion transfer and people hadn’t seen anything like it up until that point. Having a mattress with low motion transfer will be ideal for people who don’t sleep alone and have different sleeping habits. If you’ve ever had a fussy sleeping partner and you slept together on a mattress with terrible motion transfer results, you most likely woke up because the mattress moved underneath you too much. The Avena layer has a lot to do with this low motion transfer, because the top layer is bouncier rather than absorbent.

Based on a lot of customer opinions and feedback for the Leesa mattress, it is pretty clear that, while a lot of people take benefit in using this product, the most satisfied customers are the ones who like to sleep on their back or on their stomachs. This makes sense, considering that this is a medium-firm mattress, which means that it’s able to provide correct spinal alignment and proper support for these particular types of sleepers.

The Leesa, while a great bed for just about any sleeper, wouldn’t be the best choice for those who sleep on their sides. Also, those who prefer to be warm when they sleep may want to move on from the Leesa as an option because of its cooling properties.
