Modern manufacturers do not get tired of pleasing their consumers with new models of sofas. Consider and compare spring and PPU, what qualities they have and what are their features. We will help to understand in more detail the choice.

Features of the spring sofa

In the spring, there are some distinctive features, which are the filler spring unit. The spring block has three types:

Block with a snake system. Consists of serpentine, curved, flat springs. They are attached to the base of the frames and create a springy quality effect. This unit is used in arranging backs 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.

Bonnel spring block. It bears the name of a famous company. It 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 a person with a lower weight will simply slide down to a person with a larger weight. It is not comfortable.

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

What to choose, spring or polyurethane sofa

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

1. Comfort. Both sofas are available, however, in PPU models, comfort has extensive boundaries.
2. Spring blocks in the first embodiment create some inconvenience in use. And in the second, the springs are packed in separate bags, which allow you to get a good rest.
3. Thoroughness plays a huge role in choosing. The best option is PPU, in which the material is more durable. And on spring blocks there are problems with loads that are not maintained.
4. Cost. Spring ones cost much more than PUF sofas. But there are also cheap models with inexpensive cost of the material itself.

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