Do you manufacture armchairs? Choose the right polyurethane foam

When it comes to renewing or manufacturing an armchair, one of the most important aspects to consider is the type of foam that will be used as filling. The right choice not only ensures comfort and durability, but also ensures that the furniture maintains its shape and functionality over time.

In this article, we will explain how to select the ideal polyurethane foam for armchairs, highlighting its characteristics, densities, and benefits. Additionally, we will share practical tips to help you make the best decision.

Why choose polyurethane foam for armchairs?

The polyurethane foam is the most used material in the furniture industry, and it's easy to see why. This material offers a unique combination of comfort, resistance, and versatility that makes it ideal for armchair filling. Among its main advantages are:

1. Superior comfort: Polyurethane foam adapts to the body's contour, providing ergonomic support that enhances the user experience.
2. Durability: This material is highly resistant to wear and retains its original shape for years, even with intensive use and depending on the density.
3. Variety of densities: Polyurethane foam is available in different densities and levels of firmness, allowing customization of the armchair's comfort and functionality according to the user's needs.
4. Easy maintenance: It is an easy-to-clean material, ideal for homes with children or pets.

Types of densities in polyurethane foam

The density of the foam is a key factor when choosing the filling for an armchair. This parameter is measured in kilograms per cubic meter (kg/m³) and determines the material's durability. Below, we explain the most common options and their applications:

1. Low-density foams (14-22  kg/m³)

• Characteristics: They are lightweight, however, due to their low density, they are not recommended for supporting high weights.
• Recommended use: Ideal for backrests or decorative cushions, as they do not receive as much weight as seats.

2. Medium-density foams (24- 40  kg/m³)

• Characteristics: This range is the most used in armchairs. They offer a perfect balance between comfort and durability that adapts well to the body.
• Recommended use: Perfect for seats, as they support the body's weight without deforming easily. They are also suitable for backrests in frequently used armchairs.

3. High-density foams (45 kg/m³ or more)

• Characteristics: These foams are extremely resistant. They are ideal for furniture that requires high quality.
• Recommended use: They are used in high-end armchairs or in areas where high support is needed, such as in furniture designed for older adults or with specific support needs.

How to know if a foam is of quality?

The quality of polyurethane foam depends not only on its density but also on its ability to recover. A high-quality foam should return to its original shape quickly after being compressed. This attribute, known as "return," is a key indicator of durability and comfort.

Additionally, it is important to choose certified foams that meet safety and sustainability standards. At ECSA we specialize in producing polyurethane foams designed to meet the most demanding market needs.

Tips for choosing the right foam for your armchair

1. Define the use of the armchair: If the armchair will be for occasional use, you can opt for a medium-density foam. For armchairs in heavy use, such as those in the main living room, choose a high-density foam.
2. Consider the firmness: The ideal firmness depends on personal preferences. Some people prefer softer seats, while others seek firmer support.
3. Evaluate the design of the armchair: Armchairs with removable cushions can benefit from different densities for the seats and backrests.
4. Consult with experts: If you have doubts, do not hesitate to contact specialists in polyurethane foams. Send us a message, we will help you make the best decision.

Additional benefits of polyurethane in armchairs

In addition to its durability and comfort, polyurethane foam has other advantages that make it the preferred option for armchair filling:

• Design versatility: It can be molded into different shapes and sizes, allowing the creation of innovative and stylized furniture.
• Sustainability: At the end of its useful life, polyurethane foam can be recycled, contributing to waste reduction.
