With football participation expanding globally, 7-a-side pitches have become one of the most widely used formats across schools, sports parks, community facilities, and commercial venues. Their moderate field size and flexible usage allow them to support both structured training and recreational play.
Compared with 5-a-side facilities, 7-a-side pitches require greater running range, more sustained movement, and higher demands on surface support and energy return. Compared with full-size 11-a-side stadiums, however, they often experience higher daily usage intensity and tighter maintenance budgets.
Traditional infilled turf systems may face practical challenges under these conditions—such as infill migration, localized wear concentration, ongoing maintenance requirements, and environmental management considerations.
In response, non-infill artificial turf systems are increasingly specified for 7-a-side facilities, particularly in Europe and North America, where facility operators prioritize predictable play response, durability, and simplified lifecycle management.
As a technically focused provider in the non-infill segment, Vivaturf has developed system configurations tailored specifically to the operational profile of 7-a-side football. Through controlled performance parameters and structural design optimization, Vivaturf aims to balance play characteristics, durability, environmental performance, and maintenance efficiency within one integrated system.
1. Why 7-a-Side Football Pitches Benefit from Non-Infill Systems
The defining characteristic of 7-a-side facilities is functional balance:
Medium-scale playing area (typically around 64 m × 44 m in standard layouts)
Multi-purpose use (training, amateur competition, school sports, community recreation)
Daily utilization commonly reaching 6–10 hours
Localized wear concentration (midfield, penalty areas)
Need for consistent play response with cost-efficient maintenance
These conditions make non-infill turf systems particularly suitable for several practical reasons.
Reduced Dependence on Granular Stabilization
In infilled systems, repeated play may gradually redistribute sand and rubber layers, potentially requiring periodic adjustment. Non-infill structural support eliminates this operational variable and simplifies maintenance planning.
Balanced Athlete Interaction
7-a-side football combines moderate-intensity sprinting, directional change, and repeated deceleration. Non-infill fiber architecture and density design allow simultaneous control of surface support and shock absorption, helping maintain consistent player feedback across different usage intensities.
Lower Operational Complexity
Facilities managed by schools, municipalities, or small operators often prioritize predictable maintenance requirements. Non-infill systems reduce the need for material replenishment and specialized upkeep while supporting efficient installation schedules.
2. Technical Performance Framework for 7-a-Side Non-Infill Turf
Vivaturf 7-a-side systems are engineered to align with FIFA-referenced performance ranges and national testing frameworks such as GB/T 36057-2018, while reflecting real-world operational conditions.
2.1 Player-Surface Interaction Parameters

Vertical deformation: 2.3–3.6 mm
Ball rebound ratio: 0.73–0.87
Rolling friction coefficient: 0.43–0.56
Sliding resistance: 0.42–0.53
These ranges aim to provide controlled impact attenuation while maintaining efficient force transfer during acceleration and directional movement.
