What is a Sprung Floor?

A sprung floor helps prevent injuries.

The most important part of any dance floor is the suspension system. It should create resilience, the absorption and return of energy through the floor. Properly done the foam blocks create an even point elasticity (compression) over the entire ballet floor, tap floor or exercise floor when landing. These foam blocks can be most likened to wearing running shoes instead of moccasins to run a marathon.

Four Different Suspension Methods:

  1. Closed-cell, foam blocks adhered to the bottom of the subfloor.
    1. This option provides the best resilience.
    2. Closed-cell foam blocks will retain functionality for well over 20 years.
    3. Floor height is only increased by 1.5” to 1.75”overall.
    4. Foam blocks are the choice product when building a modern sprung floor.
  2. Full Roll Padding under the sub floor.
    1. Padding provides shock absorption but not much resilience or energy return.
    2. Full roll padding, if made of closed cell foam, will last for years, but because there is no “unpadded space”, dancers often have a hard time feeling the resilience of the floor.
    3. Height of floor will vary between 1.5” and 2.5”, depending on foam thickness.
  3. Rubber strips under subfloor.
      Least desirable, but still provides some resilience.
  4. Basket Weave
    1. This is the original method of constructing. These were use in theatres and dance halls for years, but are not used much anymore.
    2. With the basket weave style floor, soft spots will develop where there isn’t any wood support structure.
    3. Basket weave floors are 3-4″ in height.

Not a Sprung Floor:

  • Plywood stringers on top of a cement floor do NOT make a sprung floor.
  • Roll-out vinyl on top of a cement floor does NOT make a sprung floor.


Sprung Dance Floor Basics

O’Mara dance floors are crafted in the United States, using the finest materials available.


Cable System Install

Foam Blocks

Vented Trim

Transition Ramp

We are the only company that ships your dance floor custom sized to fit your space. Dance floor panels interlock with a continuous tongue and groove system, and our patented Cable Tuned™ System holds the sprung dance floor in place while keeping the seams tight. Few carpentry skills are necessary for installation. The clamp and cable sets allow the floor to be removed and taken to a new location.

The surface height is 1.5”. Ramps create a smooth transition between your sprung floor and existing floor.

Installed, the floor sits 1.5” away from each wall. Vented trim covers the gap between the dance floor and the walls; it lays flat on the dance surface, goes up the wall .75” and extends into the room 2.75”.

Our Ash and Maple floors are both a subfloor and finish floor in one; no other dance surface is necessary. These are finished with WearMaster XE ceramic urethane, the hardest, longest-wearing finish in the industry. Our Birch panels are designed to be covered with dance vinyl or the finish floor or your choice.
