These springs work in tandem to distribute body weight evenly, enhancing durability and responsiveness. The biconical design allows for better flex and movement, making the mattress suitable for various sleeping positions. This type of mattress is often favored for its balance of firmness and softness, contributing to a restful night's sleep.
