Not all coils are created equal
Just because they’re separated from your body by cushioning, doesn’t mean coils can be of inferior quality. The shape of the coil, thickness of the wire, and how the coils interact with each other all affect the contour, comfort, support, and durability of a mattress.
Most manufacturers make their beds with a Bonnell coil system. The steel used to make these springs is usually low grade, they tend to wear out and lose elasticity, causing a mattress to sag and fail at providing crucial support. Bonnell coils do not provide targeted contour.
A continuous coil system is an interconnected network of coils. The linked system means less sagging, but inaccurate contour. Instead of mapping your body shape, the entire spring system yields under the heaviest weight.
In a pocketed coil system, each coil works independently from the rest. This type of coil provides the best body mapping because the coils respond independently.
At European Sleep Design we use high-performance German and English pocketed coils
Each spring is individually pocketed so that it can move independently of its neighbors. This makes them highly flexible and provides perfect point elasticity as each spring can adjust to your body weight. Our pocketed construction allows for differentiated conformation to your body weight and shape, makes the mattress virtually motion-free and avoids the crunching, squeaking noise when you move.
The coil count in a good standard Bonnell core is typically around 390 coils per Queen size – this compares to 1127 in our Baltic model and 945 in our Mediterranean 3 model with an additional 1551 top coils. These higher coil counts ensure better body conformation and spinal support.
Like all our materials, our coils have been certified free of harmful substances by Oeko-Tex, the independent European testing board.
