The number of coils in a mattress can be a factor in determining its comfort and support level, but it's not the only factor to consider. The number of coils typically matters more in traditional innerspring mattresses, where the coils provide the primary support system. However, with the advancements in mattress technology, especially the development of memory foam, latex, and hybrid mattresses, the number of coils becomes less of a sole determinant for comfort. (In the thirty plus years I've been in the business it was never a determining factor, in fact the main reason a high coil count mattress felt more comfortable was the comfort layers placed on top of those spring systems were better quality)
There isn't a specific point where the number of coils doesn't matter, but rather, it's about finding a balance between coil count, coil quality, and the overall construction of the mattress. Other factors that come into play include the type of coils used (traditional Bonnell coils, individually wrapped coils, etc.), the gauge of the coils (thickness), the quality of the mattress materials, and the layering of different materials within the mattress. (any coil count over 500 in a double size mattress is sufficient)
When choosing a mattress, it's important to consider your own preferences and needs, such as your preferred level of firmness or softness, any specific support requirements (e.g., for back pain), and whether you tend to sleep hot or cool. Many people find that factors like foam layers, pillow tops, and the overall composition of the mattress can have a significant impact on their comfort and sleep quality, sometimes even more so than the exact number of coils. (These factors are always more important other than the use of a pillow top which is strictly a cosmetic difference)
In summary, while the number of coils in a mattress is a factor to consider, it's not the sole determinant of comfort. It's best to try out different mattresses and consider a combination of factors to find the one that suits your individual preferences and needs.
