Our spring mattresses combine pocket or continuous spring units with foam and fiber comfort layers to deliver balanced support, airflow, and motion isolation. Standard sizes range from Single to King, with overall heights typically between 20-35 cm depending on the number of comfort layers used. Pocket spring designs provide zoned support and reduced partner disturbance, while continuous spring units offer a more economical option with reliable long-term durability. Comfort layers commonly include HR foam, memory foam, or fiber padding, finished with knitted or quilted fabric covers for a soft, breathable sleep surface. All mattresses are compressed and roll-packed for efficient container shipping, significantly reducing freight costs for international buyers. As an experienced spring mattress manufacturer, we support custom firmness levels, sizes, and private labeling for OEM and wholesale orders.
