Launched in 2015, Leesa is one of the biggest names in the online mattress world and currently sells two mattresses, an all-foam mattress and a hybrid mattress.

Helix started selling mattresses around the same time as Leesa. The company quickly gained popularity with its sleep quiz, which helps guide users to the right mattress according to their sleeping style, body weight, and other factors. Helix offers a variety of mattresses for different sleeping styles.

In this review, we’ll be comparing the namesake all-foam Leesa mattress to the Helix Midnight, a memory foam hybrid mattress. We’ll give an overview of the construction, comfort, pricing, and sleep experience of the Leesa vs. Helix so you can get a better idea of which mattress suits your individual needs.

Leesa Mattress vs. Helix Mattress – Which One Should You Buy?

While the Leesa and the Helix both offer the contouring advantages of memory foam, each mattress features unique components that will affect the sleeping experience in a different way. The following considerations may help you compare the Leesa mattress vs. Helix mattress.

Buy the Leesa if...

1. Sleep on your stomach

The springier foam in the Leesa’s top layer will prevent you from sinking into the mattress.

2. Suffer from back pain

Sleepers of average size and weight will find the Leesa provides effective support to relieve back pain.

3. Care about the social impact of your purchase

Leesa is a Certified B corporation that puts an emphasis on the company’s social impact. For every ten mattresses they sell, they donate one to charity.

4. Prefer White Glove delivery service

The Leesa offers optional White Glove delivery service and removal of your old mattress. If you feel you might need assistance for setting up your new mattress and getting rid of your old one, this might be the right option for you.

 

Buy the Helix if...

1. Care about edge support

If you have trouble getting out of bed, or if you spend a lot of time sitting on the edge of your bed, the Helix mattress offers a clear advantage with its superior edge support.

2. Share the bed

Motion transfer in the Helix is negligible, so you won’t have to worry about disturbing your partner during your midnight trip to the bathroom.

3. Are a side sleeper

Thanks to the combination of memory foam and pocketed coils, the Helix Midnight mattress does an excellent job of providing contoured support when sleeping on your side.

4. Want a bouncier feel

While the Leesa’s LSA200 foam does a good job of imitating the bounciness of latex, the pocketed coils in the Helix mattress may provide an easier transition if you’re used to a traditional innerspring mattress.

5. Sleep hot

The individually wrapped coils in the Helix mattress stimulate airflow, leading to a relatively cool sleeping experience despite the memory foam top layer.

 

The Leesa and the Helix each offer clear benefits depending on the sleep experience you’re looking for. Both companies are highly respected within the mattress industry, with thousands of happy customers to vouch for them. If you’ve narrowed down your decision to the Leesa or the Helix, you can be confident you’re buying a well-designed mattress made with quality materials.

Mattress Construction Comparison

Leesa

The Leesa mattress is made of three layers of foam and is 10 inches thick. On top is a 2 nch layer of Leesa’s proprietary LSA200 cooling foam with an indentation load deflection (ILD) of 13 and a density of 3 pounds per cubic foot (PCF). This foam provides airflow and resembles latex in its bounciness. Side sleepers will find this an improvement from the old Avena foam, which didn’t provide as much pressure relief.

Next is a 2 inch layer of contouring memory foam with an ILD of 9 and a density of 3 PCF. This layer cradles the body and relieves pressure points.

The 6 inch support core is made of a high-density (HD) polyfoam with an ILD of 32 and a density of 1.8 PCF.

The mattress is encased in a flame-retardant sock. The seamless outer cover is a soft polyester and Lycra® blend decorated with Leesa’s signature four-stripe design.

Helix

The Helix Midnight is a 12 inch tall high hybrid mattress. The top comfort layer is a proprietary HD Memory Plus Foam with an ILD of 10 and a density of 2.5 to 4 PCF. The memory foam contours to the shape of your body.

Next is a transition layer of high-grade polyfoam with an ILD of 20 to 55 designed to relieve pressure points and provide ergonomic support. Both comfort layers have a medium firmness. Below that is an 8 inch layer of individually wrapped coils which form a cradle according to your specific body shape.

The base layer is DuraDense HD polyfoam with an ILD of 55. The cover is made from 100% polyester which is slightly stretchy and provides good airflow. The Helix Midnight is also available in a Luxe version which is slightly thicker, with zoned lumbar support and extra comfort layers.

Firmness Comparison

Comfort is one of the most important things people look for in a mattress. We usually describe comfort in terms of how hard or soft the mattress is, otherwise known as firmness. Firmness is subjective - one person might prefer a soft or “plush” mattress while another might prefer a harder one. However, it’s safe to say a majority of people opt for a medium-firm mattress. This equates to about a 5 to 7 on a scale of 1 to 10, with 10 being the firmest.

In general, memory foam mattresses tend to be on the plush side, and latex and innerspring mattresses tend to be firmer. However, this can vary widely depending on the mattress. Some mattress companies offer several firmness options.

The Leesa comes in a single firmness level, medium-firm or about a 5 or 6 out of 10 on the firmness scale. The top layer prevents users from sinking in too deeply, while the memory foam underneath provides contouring support and reduces pressure points when sleeping on your side. Because the top layer is made of a bouncier foam, lighter users may find they don’t sink deeply enough to appreciate the plush memory foam layer. In turn, heavier individuals may find the mattress is not firm enough and fails to provide adequate support.

The Helix also has a medium feel, about a 5 or 6 on the firmness scale. The thin foam layers allow the user to sink in a little, but the springs underneath provide a firm platform underneath. Heavier individuals who sink through the upper foam layers may find the mattress too firm. Stomach sleepers may want a mattress with a firmer top layer.

Sleep Experience

The Leesa is an all-foam mattress, while the Helix is a hybrid with memory foam and pocketed coils. While the two mattresses share many advantages, their slightly different designs mean they have some differences that may help you choose between the Helix vs. Leesa.

Temperature Control

Memory foam mattresses tend to sleep hot due to their exceptional contouring abilities and natural heat retention properties.

While it sleeps hotter than non-foam mattresses, the proprietary foam in the Leesa’s top layer is breathable and more resilient than memory foam, meaning users won’t sink into it as much. This helps increase airflow and helps the mattress sleep cooler than other memory foam mattresses.

The top layer of the Helix is memory foam, but the pocketed coils go a long way in stimulating airflow. As a result, the Helix is a solid choice for people who sleep hot.

Motion Transfer

When you can toss and turn without your movements affecting the other parts of the bed, that bed is said to have good motion isolation. Since memory foam responds locally to pressure, memory foam mattresses tend to have excellent motion isolation.

The individually pocketed coils in the Helix ensure that the bed only moves in the area where pressure is being applied. Along with the memory foam top layer, this ensures near-perfect motion isolation.

Despite the bouncy top layer, the Leesa also does well on motion transfer. However, if you’re sharing the bed with a very restless partner or pet, you might prefer the Helix.

Responsiveness

The comfort layers in a responsive mattress compress and contour in response to pressure. This reduces pressure points on heavier parts of your body such as your shoulders and hips, while providing support to keep your spine aligned.

Since the Leesa doesn’t have memory foam in the top layer, it doesn’t hug the body quite as tightly as other memory foam mattresses. Nevertheless, the foam comfort layers in the Leesa do encourage proper spinal alignment. This makes the mattress is popular with side and back sleepers, as well as people who suffer from shoulder and back pain.

The memory foam top layer in the Helix gives more of a “hug” feeling than the Leesa. Side sleepers will appreciate the way it contours to the hips and shoulders to provide pressure relief.

Resilience and Bounce

A resilient mattress is a mattress that quickly springs back to its original shape once pressure is no longer applied to it. You could think of a resilient mattress as being bouncier than a non-resilient mattress. Resilient mattresses are easier to move around in, and you are less likely to feel stuck in a resilient mattress. This makes it easier to change sleeping positions.

The top layer of the Leesa is made of a proprietary foam that somewhat resembles latex. It’s bouncy without the noise of innerspring coils, which is an advantage for sex. This resilience also helps prevent the feeling of sinking into the bed which is typical of memory foam mattresses.

The pocketed coils in the Helix provide a decent amount of bounce despite the fact that the top layer is made of memory foam, which is a very non-resilient foam.

Edge Support

The Leesa mattress doesn’t have reinforced edges, and the foam will compress as you sit or lie on the edge of the bed. This may cause the bed to feel slightly unstable at the edges. It can make it hard to get in and out of bed, and inconvenient for sitting on.

The individually wrapped coils in the Helix have a reinforced perimeter, giving much better edge support than the Leesa. If you value edge support, you may prefer the Helix.

Off-gassing and Smell

The Leesa is CertiPUR-US® certified, and the Helix is CertiPUR-US® and OEKO-TEX® certified, meaning they are low in volatile organic compounds (VOCs) and other harmful chemicals. Both the Leesa and the Helix emit a faint off-gassing odor when they are taken out of the package but this is nothing to worry about. The smell is not harmful and should dissipate within a few days in a well-ventilated room.
