Pocket Spring: Indicates you want individually pocketed coils, not a zigzag/sinuous spring. This is a premium feature for sofa

 cushions, offering superior comfort, motion isolation, and contouring compared to standard webbing or foam cores.

Custom Size: The core requirement. You are not looking for a standard off-the-shelf unit but one built to your exact dimensions.

18" x 18" x 4": The specific custom dimensions.

18" x 18" (L x W): This suggests a single, large seat cushion module. This is a common size for a single-seat cushion on a

medium to large sofa.

4" (H): This is the height of the spring unit. A 4-inch spring unit is designed for a medium to high-profile cushion, providing

significant support and a plush feel. The final cushion height will be this plus the thickness of the upholstery foam on top.

For Sofa Cushion: Defines the application, which is crucial for the factory to recommend the appropriate spring gauge and count

 for the required support.
