Micro pocket springs (or micro-coils) are, compact, 1–4 cm tall springs individually encased in fabric, designed to act as a high-density comfort layer in premium mattresses, particularly hybrids. They offer enhanced, targeted body contouring, superior pressure relief, and increased airflow compared to traditional upholstery layers, although they offer less structural support than main-unit coils. Key Characteristics and Benefits High-Density Support: Hundreds or thousands of these small coils can be packed into a single mattress, offering precise,, tailored support that adapts instantly to body movements.Enhanced Comfort Layer: Often used on top of a base layer of traditional pocket springs to provide a plush, cushioning feel similar to a pillow-top, while offering more responsive support than foam.Motion Isolation: Because each coil is independent, they minimize motion transfer, making them excellent for couples.Breathability: The structure allows air to flow freely through the mattress, regulating temperature better than solid foam layers.Zoned Support: Many manufacturers use varying densities of micro-springs to create zones that provide softer support for shoulders and firmer support for the hips. Micro Pocket Springs vs. Traditional Pocket Springs Size & Function: Micro springs are much smaller ((1text{--}4text{ cm}) vs (approx 16text{ cm})), serving as a comfort layer, while traditional springs provide structural support.Durability: While they offer great comfort, some industry experts argue that because micro-springs are smaller and under constant compression in the top layer, they might not be as durable over the long term as traditional, larger coils. Micro pocket springs are frequently used in luxury mattresses to provide a "floating" sensation, combining the responsiveness of springs with the comfort of a mattress topper.
