Polyurethane: an essential material for chairs and stools

The use of high-quality padding is fundamental for the creation of valuable products, whether it be sofas, armchairs, stools or car seats.
To obtain products that are comfortable, welcoming, soft to the touch and resistant over time, quality padding is required.
Generally, in fact, when we buy a piece of furniture we all want to try its comfort, we want to make sure of a purchase that perfectly meets our needs.

For example, there are some people that prefer to sit on a soft chair and other who prefer a more rigid chair. It is a personal choice.  Thanks to the different types of materials and procedures with which the padding is made, it is possible to satisfy the needs of all customers.
The padding of office chairs, in most cases are present with two different materials: polyurethane and resin.

But what is polyurethane foam?

Polyurethane foam

Polyurethane foam is a two-component material made up of two elements such as polyol and isocyanate which, mixed together through the foaming machines, react and use different types of product. The molding of polyurethane foam includes two types of polyurethane that differ according to their characteristics and their respective sectors of application: rigid polyurethane foam and flexible polyurethane foam.

The disadvantages of polyurethane foam padding

The seat with cold-foamed polyurethane foam padding is generally more expensive as it is a costly process that requires machines that produce few pieces which are very expensive.

The advantages of polyurethane foam padding

The advantages of polyurethane foam are versatility, functionality, strength and elasticity.
We offer a distinction between flexible polyurethane foam and rigid polyurethane foam.

Flexible polyurethane foam is an open cell polyurethane foam with a soft consistency which, thanks to the chemical reaction between the two components, can take on a solid form up to triple its volume. Flexible polyurethane is a material with a soft and flexible resistance. It is mainly used in the furniture sector as it consists of both large and small elements such as sofas, chaise longues, armchairs, pouffes and chairs.

The rigid or integral expanded polyurethane, on the other hand, is a high density closed cell polyurethane foam, it is very resistant, it has a smooth or embossed external skin depending on the customer’s needs.
