Harlequin WoodSpring is a permanently installed sprung floor system. It is a modern update of the traditional 'basket weave' construction. It is a counterbatten configuration comprising at least three layers of highly flexible softwood battens, arranged at right angles.

The intermediate layer acts as a spring to the top layer, which is laid at the centre of the span formed by the intermediate layer over the bottom layer. Theoretically, the more intermediate layers incorporated in a basket weave floor the more flexible it becomes.

In the Harlequin WoodSpring system, shock absorption and energy return are enhanced by pads attached to the underside of the bottom layer. Onto this structure are installed two layers of flexible panels (typically plywood), which support the Harlequin dance floor.

Different surface options to consider:

Engineered wood top surface in beech, oak or maple, for specifiers who need a hardwood surface for multi-purpose use, including traffic by the general public, full stage entertainment, ballroom dance or even for designers obliged to match existing décor.
Engineered board with a hardwood wear layer - in beech, oak or maple.
