When we talk about mattresses with pocket springs, there are many factors that influence their quality, durability, and comfort. One of the lesser-known but very important factors is the diameter of the springs. But... what does this mean exactly? And how does it affect your rest? We explain everything below…
What do we understand by the diameter of a pocket spring?
The spring diameter refers to the thickness of each of the individual springs that make up the core of the mattress. These springs are "pocketed," meaning they are individually wrapped in small fabric bags that prevent friction between them and allow independent movement.
The diameter can be expressed in centimeters (cm) and varies according to the design of the mattress and its level of firmness.
What does a larger or smaller diameter spring mean?
- Larger diameter spring: offers more solidity and stability. With a larger size, the support surface of each spring is wider and the pressure is distributed more evenly. Conversely, point-by-point adaptability is reduced, as the spring responds more globally.
- Smaller diameter spring: provides greater adaptability and individualized comfort. Being smaller, more springs can be placed on the same surface, allowing the mattress to better respond to the shape of the body. In exchange, a bit of structural firmness is lost.
In summary, a large diameter reinforces stability, while a smaller one enhances ergonomics and adaptation to the body.
Mattresses on our website according to the diameter of the pocket spring
At muellesensacados.es we have mattresses of different pocket spring diameters. As we have seen earlier, it is not that some are better than others, but depending on our expectations, some will adapt better than others to our needs. Below we classify the mattress models according to the diameter of their pocket springs:
Smaller diameter mattresses: more adaptability
Mattresses with smaller diameter pocket springs offer greater adaptability and comfort. We have classified in this block the models that have pocket springs with a diameter between 3.8 and 5.5 cm. You can check each of them by clicking on their names:
- Mattresses with pocket springs of 3.8 cm in diameter: Rocket from Descansor and Titan, Royal and Carisma from Sonpura.
- Mattresses with pocket springs of 4 cm in diameter: Magnum from Relax and Gaudí from Sonpura.
- Mattresses with pocket springs of 5 cm in diameter: Five Areas and Cotex from Descansor, Infinity from Poligón and Everest and Gaviota Oro from Relax.
- Mattresses with pocket springs of 5.5 cm in diameter: Ona and Varu from Astral, Pentatlon, Supra XXL medium-firm, Supra XXL firm, Box XXL and Wasamemucho from Descansor.
Larger diameter mattresses: more stability
Mattresses with larger diameter in their pocket springs offer greater stability and solidity. We have classified in this block the models that have pocket springs with a diameter between 6 and 7.2 cm. You can check each of them by clicking on their names:
- Mattresses with pocket springs of 6 cm in diameter: Polar and Persa from Hilding Anders.
- Mattresses with pocket springs of 6.1 cm in diameter: Lotus, Indra and Fusion from Sonpura.
- Mattresses with pocket springs of 6.2 cm in diameter: Suite Confort and Natural Spring from Descansor.
- Mattresses with pocket springs of 7.1 cm in diameter: Game, Play, Solei, Prisma and Golden from Sonpura.
- Mattresses with pocket springs of 7.2 cm in diameter: Uansait, Visco Ensacado and Stark from Descansor.
The importance of the support base
We already know the importance of the diameter of pocket springs, but to achieve a comfortable and durable sleeping system, the base on which we place our pocket spring mattress is also important.
The most recommended option is the rigid base (box spring or upholstered base). This type of surface offers continuous and uniform support, maximizing the performance and durability of the mattress.
Even so, pocket springs can also work well on slatted bases, but if we choose to place the mattress on a slatted base, we must keep in mind a key aspect: the diameter of the spring must be greater than the gap between the slats. Otherwise, the spring could get stuck in the gap, deform, or shorten the lifespan of the mattress. For example: if we have a base with a gap of 6 cm between its slats, we should not place a pocket spring mattress with a diameter of 6 cm or less; we need to choose one with pocket springs of a larger diameter. A good option is multilayer slatted bases, which usually have a smaller space between their slats.
Conclusion
The diameter of pocket springs is not a minor detail. Larger springs provide stability and firmness, while smaller ones offer greater adaptability. And, whatever the choice, do not forget that the support base is as important as the mattress itself for enjoying quality rest.
