Effect of Different Mat Characteristics on Trampolines

Narrated by Mr. Charles (a teacher), written by Ammar Masoud and edited by M Waqas Saeed.

Recently, one of my high school students was bouncing on my new trampoline and I noticed the stretch of the mat seems to make a big difference in the bounce. This got me thinking more deeply about how the characteristics of the mat impact the trampoline experience. As both a long-time jumper and a trampoline owner, I set out to do some research on this topic to understand the effect of different mat components.

How Trampoline Mats Work?

The mat is one of the most important parts of a trampoline. Here’s a quick overview of how trampoline mats function:

• The mat sits on top of the trampoline frame and springs. It provides the jumping surface.
• When you jump, the mat stretches downward, pulling the springs with it.
• The stretched springs then recoil back upwards, projecting you up into the air.
• This creates a continuous cycle that gives you the bouncing motion.

The characteristics of the mat determine how much it will stretch and rebound during use. This impacts important factors like:

• Bounce efficiency – How much energy return you get with each jump
• Bounce feel – The softness, springiness and responsiveness of the surface
• Bounce height – The maximum height you can reach with your jumps
• Durability – How well it withstands repeated use over time

Below I analyze how different mat components like elasticity, thickness, materials and weave affect these bounce characteristics.

Elasticity Controls Energy Return

The elasticity of the mat determines how much it will stretch downward when you jump on it. This controls:

• Energy absorption – More stretch allows it to absorb more of the energy from your jump
• Energy return – The recoiling springs then convert this absorbed energy into upward thrust

More elastic materials, like woven fabrics, provide higher energy return. With each jump, you sink deeper into the mat before getting projected back up. This gives better bounce efficiency – more of your downward energy gets recycled into lift.

Less elastic materials, like non-stretch vinyl, absorb less energy. The mat stays firmer under your feet rather than stretching down to tap the spring potential. This poorer energy return means less recoil thrust on each bounce.

Comparison of energy return of common mat materials:

Thickness Impacts Bounce Feel

The thickness of the mat influences the softness and responsiveness underfoot:

• Thinner mats feel harder and more firm. There is less cushioning so impacts feel more jarring.
• Thicker mats provide more padding for a softer, more forgiving bounce. But thickness beyond a point can dampen spring response.

Gymnast trampolines often use thin 1-2 mm vinyl or Permatron mats prioritizing control and stability over cushioning. Garden tramps for recreational jumpers use thicker padded fabrics for extra softness. I find around 4-5 mm mats provide the best blend.

Material Durability Varies

The mat endures substantial mechanical stress from repetitive jumping. Material durability determines lifespan:

• Vinyl mats are most vulnerable to tears, splits and punctures from wear-and-tear.
• Permatron is extremely durable with interwoven polymer layers resisting degradation.
• Woven fabrics like Polypropylene are reasonably durable but still wear faster than Permatron.

I ensure only high grade durable materials are used for my personal tramps. This reduces need for early mat replacements.

Weave Impacts Consistency

For fabric mats, the weave pattern affects surface uniformity:

• A tighter uniform weave minimizes irregularities for consistent even bounce across the mat.
• A looser weave can cause certain areas to stretch more leading to unevenness in the rebound lift.

I really notice this when multiple people are jumping. If the weave is uneven, some spots feel softer or bouncier disrupting your rhythm. Good quality tightly woven mats bounce the same everywhere providing better consistency.

Conclusion

The trampoline mat has a huge influence on key bounce characteristics. Variables like material elasticity, thickness, durability and weave all contribute to factors like efficiency, feel, height and uniformity. As both an enthusiast and trampoline owner, understanding these dynamics helps me select mats optimized for an exceptional, high-performing bounce.
