Safety, safety, safety. Please do NOT compromise safety when choosing a lawn for a playground. Your starting point or minimum face weight to be considered would be 60oz, we will always recommend a heavy face weight. We suggest going with the highest face weight your budget will allow, to ensure built in safety. A heavier face weight produces a dense, soft and safer surface. When installing a synthetic turf surface beneath any playground equipment, we strongly recommend installing our ‘Under Base System’. This uniquely designed foam pad system can achieve a fall rating of up to 9’.
