Advancing sprung gym flooring
for gymnastics performance
Explore how Lesjöfors engineered precision coil springs to improve performance, durability, and energy return in sprung gym flooring.

Project overview: enhancing Tumbl Trak’s sprung flooring
When watching a gymnast flip, tumble, twist, and land with precision, it’s easy to overlook the engineered system working beneath the surface. Under the mat sits a carefully configured web of sprung floor springs, designed to absorb impact, control rebound, and support the needs of the gymnast.
Working with Tumbl Trak, an international gymnastics equipment specialist, Lesjöfors developed a high-quality spring solution for sprung gym flooring – engineered to optimize athletic performance while meeting the sport’s strict safety requirements.

Design criteria for Tumbl Trak’s sprung floor springs
What was the brief?
As gymnasts continue to push the limits of performance, the equipment beneath them must keep pace. Tumbl Trak asked us to develop a high-quality spring to enhance athlete performance on their sprung gym flooring.
What makes the project special?
Gymnastics flooring has undergone various improvements over the years, with each development focused on increasing performance while maintaining the highest safety standards. Knowing that our springs form the foundation for future Olympians meant the solution had to deliver consistent and reliable results.

What did Lesjöfors do?
Material selection, design, and layout are critical to the performance of sprung gym flooring. Using premium materials and precise engineering, we delivered a spring design that enabled Tumbl Trak to supply gymnasts and clubs with high-quality training equipment – supporting their ‘Train smart’ philosophy and long-term enjoyment of the sport.
What our clients say

Manufacturing sprung floor springs
Due to the size and material requirements of the compression spring design, the sprung floor springs were manufactured using advanced cold coiling, followed by heat treatment to enhance strength and fatigue performance. To meet installation requirements within the floor mats, each spring end was also precision-ground to a defined specification, ensuring consistent placement.
Material selection was critical to the success of the project. The design required a carbon steel grade capable of delivering the necessary strength and durability under repetitive loading in high-pressure environments. This carbon spring steel also supports hardening treatments, providing a robust and cost-efficient solution aligned with customer expectations.

Sprung flooring springs: from design to delivery
From enquiry through to design engineering, material selection, and manufacturing, our teams liaised with Tumbl Trak at every stage to ensure we met their requirements and dispatched on time.
Given the high-volume nature of the order, Tumbl Trak also chose to use our free stock holding facility, allowing them to call off stock as required to support their production planning.
