A playground turf surface is only as good as its tested critical fall height. The CPSC Public Playground Safety Handbook, which New Jersey adopts for public playgrounds, says the surfacing's critical height rating should be at least the fall height of the tallest equipment. Turf alone doesn't get a rating; the whole tested system does (turf, infill, pad and base). Published examples: ForeverLawn Playground Grass over SafetyCel, rated by ForeverLawn at a 15-foot critical fall height, for the tallest equipment. Turf over a Brock PowerBase PLAY80 pad, rated up to 12 feet with a compatible tested turf system, or PLAY50, up to 9 feet, for typical school and park structures. Brock YSR (up to 5 feet) and SP Series (up to 4 feet) suit low toddler equipment. SYNLawn SYNPlay 48 with Pad is a low-pile activity turf listed as ASTM F1292-tested, but we found no published fall height, so treat it as an activity-zone surface unless the quote includes a test report for your height.

The CPSC handbook is blunt about surfacing. It lists concrete, asphalt, dirt and natural grass as inappropriate under playground equipment, and it also lists "carpet not tested to ASTM F1292". Artificial turf on its own is, functionally, a carpet. What makes a turf playground acceptable is the layer under it, usually a shock pad or foam base, and proof that the complete assembly was drop-tested to ASTM F1292.
That test drops an instrumented headform onto the surface from increasing heights and measures peak acceleration (G-max) and Head Injury Criterion (HIC). The highest height that stays under the limits is the surface's critical height, which the handbook defines as "the fall height below which a life-threatening head injury would not be expected to occur." The handbook also notes that some injuries, like broken limbs, can happen on any surface. Critical height is about head injury.

The CPSC handbook defines fall height as the vertical distance between the highest designated play surface on a piece of equipment and the protective surfacing beneath it. For most climbers it's the highest part of the climbing component, and for a composite structure it's the highest part intended for foot support. The equipment manufacturer's paperwork usually states it. Write down the tallest fall height on the playground, because that number decides which pad you need. Pad thickness can vary across a site, with transition wedges between zones, as long as each zone meets the fall height of the equipment over it.
New Jersey's Playground Safety Subcode (N.J.A.C. 5:23-11) adopts the CPSC handbook by reference for public playgrounds. The handbook's definition of "public" covers schools, parks, commercial child care centers, multifamily housing, restaurants, resorts and other public-use areas. Home backyard playsets fall outside it, but the same fall-height logic is a sensible target at home.

ForeverLawn markets Playground Grass as the first synthetic turf rated exclusively for playground surfaces. Its Playground Grass Ultra spec sheet lists a 1-1/2 inch dual-yarn construction (polyethylene slit film plus textured nylon), 48 oz face weight and 103 oz total weight, a three-layer BioCel polyurethane backing, XStatic antistatic technology, AlphaSan antimicrobial protection, and infill of 0.75–1 lb of rubber and 3.75–4 lb of sand per square foot. The line sheet says premium-backed Playground Grass products carry a 15-year warranty and meet ASTM F1292 and ASTM F1951. Under the turf, ForeverLawn's SafetyCel base is rated at a 15-foot critical fall height and comes with an "8 x 8" safety surface warranty, guaranteed to meet ASTM F1292 for 8 years at 8 feet. ForeverLawn also takes part in IPEMA's third-party certification program and says it retests at least 20 percent of its validated surfacing products each year. Its construction spec requires independent F1292 results at 32, 72 and 120 °F, below 200 G and 1,000 HIC. That's the level of paperwork to ask for from any vendor.
Brock describes PLAY80 as an 80 mm molded expanded-polypropylene pad for critical fall heights up to 12 feet, with lateral drainage. Its single-layer design avoids stacking multiple pads for taller equipment. Like every Brock rating, the 12 feet applies to the complete tested assembly, so the turf and infill have to match a configuration Brock has tested.
PLAY50 is a 50 mm (2 inch) EPP pad in 24 square-foot interlocking panels, rated for critical fall heights up to 9 feet with a compatible tested turf system. Brock lists vertical and lateral drainage above 1,500 inches per hour, no glues or tapes at the seams, and a 10-year warranty with an HIC and G-max guarantee. Brock also sells transition wedges (48 inches wide, 1:13.7 slope) to step between PLAY50, PLAY80 and YSR zones on the same site. For many New Jersey school and park structures, a 9-foot rating covers the tallest deck. Check your equipment paperwork.
Brock rates its 25 mm YSR pad for critical fall heights up to 5 feet (lateral drainage) and its 20 mm SP Series up to 4 feet. The CPSC handbook says toddler platforms should be no more than 32 inches from the ground and gives 32 inches as the maximum fall height for toddler climbing structures, so a thinner pad can be appropriate in a dedicated toddler zone, as long as the tested rating covers every piece of equipment in it.
SYNPlay 48 with Pad is a 3/4 inch, 48 oz low-pile polyethylene turf with a 5 mm attached cushion (120 oz total weight, 15-foot rolls) and a limited lifetime warranty. SYNLawn markets it for daycares, gyms, agility courses and play areas, and lists ASTM F1292 and F1951 in its test data, but the product page we checked doesn't state a critical fall height. Use it for activity zones, open play and ground-level play. The CPSC handbook says equipment where children's feet stay on the ground, like playhouses and activity walls, isn't covered by the surfacing recommendations. Put it under elevated equipment only if the quote includes an F1292 report showing a critical height at or above that equipment's fall height, often with a separate pad.

Get a QuoteThe right system is the one whose tested critical fall height is at least the fall height of the tallest equipment on your playground, which is what the CPSC handbook (adopted by New Jersey's Playground Safety Subcode) recommends. For tall equipment, published examples include ForeverLawn Playground Grass over its SafetyCel base, which ForeverLawn rates at a 15-foot critical fall height, and turf over a Brock PowerBase PLAY80 pad (up to 12 feet with a compatible tested turf system). For typical preschool equipment, Brock PLAY50 (up to 9 feet) or YSR (up to 5 feet) may be enough. Ask for the ASTM F1292 test report for the exact turf, infill, pad and base being quoted.
Only as a tested system. The CPSC Public Playground Safety Handbook lists carpet not tested to ASTM F1292 as inappropriate surfacing and says manufacturers and installers should provide a critical height rating for their surfacing that is at least the fall height of the highest equipment. Turf alone is a carpet. Turf plus a tested shock pad or foam base, installed to the manufacturer's tested configuration, is what earns a critical fall height.
The CPSC handbook defines critical height as the fall height below which a life-threatening head injury would not be expected to occur. It comes from ASTM F1292 drop tests that measure G-max and Head Injury Criterion (HIC). ForeverLawn's Playground Grass specification, for example, requires results below 200 G and 1,000 HIC at 32, 72 and 120 degrees Fahrenheit.
New Jersey's Playground Safety Subcode (N.J.A.C. 5:23-11) adopts the CPSC Handbook for Public Playground Safety by reference for public playgrounds, which the handbook defines to include schools, parks, commercial child care facilities and multifamily housing. Home backyard playsets aren't covered by the handbook, but the same fall-height logic is a sensible target.
Some systems are designed for it and some aren't. The CPSC handbook says playgrounds should never sit directly on hard surfaces, and the shock pad or foam layer is what does the impact work. Ask the manufacturer whether the exact tested assembly includes your base type, and whether drainage can leave the pad.
DreamFields quotes after a site visit, because equipment fall heights, area, base condition, drainage and the pad thickness required all change the number. Our playground turf installation cost guide explains those factors. Make sure every quote names the turf, pad and infill and attaches the F1292 test report.
