How a Memory Foam Mattress Is Made? | Noobs Guide

Published On:

Memory foam mattresses are recognized as one of the best mattresses worldwide.

According to research, around 66% of people think memory foam is the best mattress type.

Whether it is their high comfort level, customized support, good pressure relief, or more, they help us provide the sleep we need.

Even though memory foam mattresses are highly used among people, still most people have no clue how these memory foam mattresses are made.

If you cope with the same question and want to know how a memory foam mattress is made, you have reached the correct place.

In this article, we will specify everything about how a memory foam mattress is made, including the components involved in the manufacturing process.


Process Of Building A Memory Foam Mattress

Making a mattress requires proper components and building methods. In terms of memory foam mattresses, the main element used for manufacturing their mattress is polyurethane plastic. This component then gets divided into two sections of petrochemicals known as polyols and monols.

Polyurethane is highly crucial for the chemical reactions to take place in creating a memory foam mattress. Polyurethane is produced from several polymer compounds that react with appropriate catalyst and water, forming cell-like shapes used for trapping air.

Exothermic Reaction

The exothermic reaction then occurs when they combine water, isocyanates, polyols, and multiple reactive substances. The combination of several components helps in forming a liquid-like consistency.

This liquid-like consistency is then utilized to load into the moulds used to form the memory foam slabs. Then this mixture is distributed evenly in the moulds or containers, which gets dried out rapidly and creates a memory foam product.


Open Cell Feature

This process of creating a memory foam mattress also includes forcing out the air, which helps generate a highly known open-cell feature.

Through this feature, the mattress gets small pockets that can allow the air to flow and make the mattress breathable. Once the slab stock foam is cooled and dried, it gets removed from the container. Then the form gets washed, dried, and the quality of the foam gets checked.

Then cutting or shaping process takes place. These foams are then cut into smaller parts or dimensions, such as the shapes of a mattress. This entire process of creating a memory foam mattress takes around eight hours.

The manufacturing process of memory foam mattresses might vary as per the manufacturer since people like to input their unique recipes by utilizing different chemical compounds.

Therefore when you buy a memory foam mattress, make sure you check the label of the mattress carefully along with the compounds used.



1. After how many years should I replace my memory with a mattress? 

You should replace your memory foam mattress after eight to ten years of use. However, if your mattress is well maintained and in good condition, you can use it for a more extended period.

2. Is a memory foam mattress suitable for comfort? 

Yes, memory foam mattresses are excellent in providing comfort. It helps in evenly distributing your weight and improving your sleeping quality by reducing pain and providing support.
