Enhanced Support with 20 Spring Rows

Upgrades to our production line have increased the number of spring rows across the unit’s width from 18 to 20. The higher spring density promotes even weight distribution across the sleeping surface.

Configured for U.S. Mattress Sizes

The 336-count spring configuration is designed for U.S. mattress dimensions, supporting mattress manufacturers serving international markets.

Tested Shape Recovery

High-pressure compression and roll-packing tests showed no spring collapse, deformation or loss of shape. Following testing, the spring unit recovered 100% of its original form.

Efficient Storage and Shipping

Roll-pack and flat-pack options optimize warehouse space and container utilization, helping reduce freight costs.
