Which sofa is better, spring or polyurethane foam

Modern manufacturers never tire of delighting their consumers with new models of sofas. Let's consider and compare spring and polyurethane foam, what qualities they have and what are their features. We will help you understand the choice in more detail.

Features of a spring sofa

The spring one has some distinctive features, which lie in the filler of the spring block. The spring block has three types:

Block with snake system. Consists of serpentine, curved, flat springs. They are attached to the base of the frames and create a high-quality springy effect. This block is used in the arrangement of backrests for a certain softness. For non-folding models it is used in seats, suitable for sofas in restaurants, bars, and kitchen furniture in the form of dining areas.

Bonnell spring block. Bears the name of a famous company. Has continuous weaving of a single block.

ATTENTION! This type has a minus: if several people with different weight categories sit on such a sofa, then the person with less weight will simply slide towards the person with more weight. It is not comfortable.

Block with independent springs. Barrel springs with a large number of up to 1200–1300 pieces, with turns of more than eight pieces.Completely eliminates possible vibrations of this design. Each spring distributes the load of a lying or sitting person. Created for the orthopedic needs of people. Each spring is distributed separately in the case and does not touch each other.

What to choose, spring or polyurethane foam sofa

Comparing the two types with each other, we highlight important points that you should pay attention to when choosing.

1. Comfort. Available for both sofas, however, for PPU models, comfort has wide limits.
2. Spring blocks in the first option they create some inconvenience in use. And in the second, the springs are packaged in separate bags, which allow you to get complete rest.
3. Thoroughness plays a huge role in the choice. The best option is polyurethane foam, whose material is more durable. But with spring blocks there are problems with loads that cannot be withstood.
4. Price. Spring sofas are much more expensive than PU sofas.But there are also cheap models with low cost of the material itself.

So, before choosing a sofa, weigh the pros and cons. Start from your needs. Choose a filler that is more convenient and harmless for you. And the question of price is a separate conversation. It’s better to pay once and use the sofa for a long time than to buy a cheap option that will have to be replaced or simply thrown away in a couple of years. You can give endless advice, but the choice is yours.
