How can you tell a liner springs apart from shader springs?

Liner springs and shader springs can be differentiated by their design and function. Liner springs are typically uniform in thickness and coil tightly, providing consistent resistance throughout their length, making them ideal for applications requiring steady support. In contrast, shader springs have a varying coil thickness or spacing, allowing them to compress more easily at certain points, which gives them a softer feel and makes them suitable for cushioning and shock absorption. Additionally, liner springs often serve structural purposes, while shader springs are used for dynamic movement and flexibility.
