1. The Quality of the Materials Used in the Mattress:

624 Mattress Quality

624 is a versatile mattress that is winning the hearts of buyers with its firmness options and quality materials. You can flip the top two layers to either feel the 4 or 6 firmness as per your comfort.

The whole mattress features several layers of natural latex, memory foam and other types of foams. To understand its quality and structure, let’s see what each layer of this mattress is made of.

Cover Layer:

There are two layers of cover in this mattress. The top cover layer keeps all the layers of the mattress together. This outer cover is made up of Kantec fabric; which has developed by the company.

This material is soft and fast drying due to which it wicks away the moisture from your body. This zippable and washable cover provides a cool and comfortable sleep to the user.

Under this cover, there are inner covers in which both layers are wrapped separately. These inner covers are made up of antimicrobial mesh that regulates the temperature.

First Comfort Layer:

There are two comfort layers in the mattress which the user can flip for experiencing different comforts. The first comfort layer is of 30 mm natural latex; which is mixed with activated charcoal.

This combination helps in preventing heat retention and absorbing impurities as well as odors from body and air. Latex is a responsive material that provides comfort by supporting your pressure points.

Second Comfort Layer:

The second comfort layer is made up of high-density memory foam; which is 40mm thick. This is viscoelastic foam that contours your body slowly. This layer provides a soft sinking feeling to your body.

This layer may retain some heat if used on the top. The sleepers can unzip the upper cover anytime to change the firmness setting by flipping these two comfort layers.

Kantec Foam Layer:

The final support layer of this mattress is high compact resistance Kantec foam; which is also designed by 624. This special foam is 190mm high and has an irregular open cellular construction which helps in regulating the airflow and minimizing partner’s disturbance. It provides much-needed support to the sleeper’s spine as well.

The mattress can sit on any firm flat surface even on the floor without moving around, due to the gripping points of its outer fabric.

The company has chosen a standard color combination of white and grey with a patterned top cover. Partners who have different sleeping preferences can purchase 2 king-size mattresses to enjoy a soft and medium-firm feel on the same bed.

2. The Feel and Firmness Level of the Mattress:

Feel and Firmness of 624 Mattress

The 624 uses a combination of latex, high-density memory foam and compact-resistant foam with two different firmness levels to meet the expectations of every distinct sleeper. Talking about the firmness, the mattress can become medium firm with the latex top layer, and it can turn to medium soft with the foam top layer.

The medium-firm side with latex on the top provides cushioning to pressure points, support, and a little bounce. This setting of the mattress is perfect for back sleepers as they need proper spinal support. Stomach sleepers will also love this firmness setting due to its supportive nature; which prevents sinking. The body-hugging feel of latex will satisfy the back sleepers as well.

The medium-soft side with memory foam on the top will be totally loved by the side sleepers. The high-density memory foam molds according to your body shape, providing it with a softer and less supportive feel.

The lack of gel also lets the airflow easily through it. The cover of this mattress is antibacterial, antimicrobial, and hypoallergenic; which makes it a good choice for people with allergies.

The irregular cell construction of its support layer eliminates the partner disturbance. Even the company has claimed on its website that their mattress is “100% partner disturbance-free”.

Well, you can check the authenticity of their claim by trying this mattress during its trial period. Apart from it, this unique layer also allows the moisture and air to pass through it without any difficulty.

3. The Edge Support of the Mattress:

The edge support of 624 isn’t that much good because it’s a foam mattress. Usually, edge support is a weaker point of foam mattresses; and the same goes with this mattress. You will feel like falling off if you will sit on the edge of this mattress.

However, you won’t actually fall because of the support of the highly compact base layer. Due to this point, people who face problems in hopping in and out of bed will find this mattress lacking.

4. The Weight and Thickness of the Mattress:

The weight of the Queen Size mattress is 32 kilograms, and it is 26 centimeters thick. Considering this, we can say that its thickness is also average as compared to the other box mattresses. You can also place it on a raised bed frame if you find it too low on a standard base.

5. The Temperature of the Mattress:

The cooling ability of this mattress is good. People who will sleep with the latex layer on the top won’t face any issues with the cooling of this mattress because latex is a naturally cooling material.

Its specialized cover also contributes to the overall cooling effect. People who live in a warm area and going to choose memory foam as the top layer can experience some heat retention. But, that’s quite normal in a foam mattress.
