They feature a durable, hard drawn high carbon steel, 2in x 4in coil with newly-designed plastic retainer caps. The caps have an additional set of grooves that keep the spring from falling out while in use, preventing dead spots in your floor. Our springs are resilient enough for gymnasts of all sizes and abilities. The hardware required (3 pieces) for each spring is included. The advantages of the Tumbl Trak Springs are that the caps are more robust, the coil paint does not flake, top and bottom caps are interchangeable, and they ship far sooner than competing springs (usually within one week).
Thinking of building your own floor? Your biggest challenge will be to find the correct plywood appropriate for spring floors. The type most all commercial manufacturers use is Baltic Birch. This type of wood is strong, resilient, and resistant to warping or cracking. We recommend a board that is 3/8in (or 9mm) in thickness because that is the size that fits the hardware we provide. The 5ft x 5ft board size is easiest to work with. You will need two layers: One layer has the springs attached to it; the other is the offset layer which ties the floor together as one unit, providing uniformity of rebound. These layers can be connected by Velcro or screws. Velcro is usually better as it is far easier to remove, repair or relocate.
There are two schools of thought regarding the number of springs you need. Some think that you just need one per square foot. However, most think that you need an extra spring along the perimeter. Generally, the gymnastics field has a stronger inclination to the extra (perimeter) springs. Just let us know if you would like pricing on the kit with or without the perimeter option.
If you are adding to an existing floor please call for a conversion kit. Attachment hardware cannot be sold separately.

No, you would need to purchase your wood separately. The type most commercial manufacturers use is Baltic Birch. This type of wood is strong, resilient, and resistant to warping or cracking. The ideal thickness is 3/8'' (or 9mm). The 5' x 5' size is easiest to work with. You will need two layers: One layer has the springs attached to it; the other is the offset layer which ties the floor together as one unit, providing uniformity of rebound.
We do not recommend using plywood for spring floors due to the weakness of that type of wood. While you can ultimately make your own decision about the type of wood you use, just know that we do not recommend that type for safety reasons. Most people who have used Plywood end up having to replace boards very often because they break from the force of the tumbling. We use Baltic Birch since it is very strong, and does not warp easily.
How do you mount the springs to the boards?
The caps are mounted to the boards using a bolt and nut which are provided with purchase. The spring screws into the top cap and the bottom cap sits on the floor. We can also provide layouts for various sizes of floors along with installation instructions.
If my current spring floor is 'dead' can I change out the springs, use the current boards, and tops to get a whole new floor?
If the boards are in good condition, not cracked or warped, then changing out the springs should work great. If any boards are broken, just replacing the section with a new board spring cap and hardware is the way to go.
