7 Best Materials to Put Under a Swing Set

When installing a swing set—whether at a public playground, schoolyard, or your own backyard—selecting the right material to place underneath is critical for safety, durability, and maintenance. As a professional playground equipment manufacturer, we understand how vital it is to protect children from falls while also offering a long-lasting and cost-effective solution.

In this guide, we’ll walk you through the 7 best materials to put under a swing set, including their pros, cons, and best-use scenarios, to help you make an informed decision.

1. Rubber Mulch

Best for: High-impact areas and long-term use

Rubber mulch offers excellent shock absorption, making it one of the safest surfacing materials. It’s made from recycled tires, providing both safety and sustainability.

Pros:

• Superior fall protection (up to 10 feet when installed correctly)

• Doesn’t decompose or attract insects

• Low maintenance

Cons:

• Higher initial cost

• Can scatter without proper containment borders

2. Engineered Wood Fiber (EWF)

Best for: Public parks and budget-conscious projects

EWF is a processed wood material designed specifically for playgrounds. It compacts well to form a stable, slip-resistant surface.

Pros:

• Affordable

• ADA-compliant when installed properly

• Natural appearance

Cons:

• Requires frequent topping-up

• Decomposes over time and can attract mold or pests

3. Pea Gravel

Best for: Drainage-focused outdoor swing sets

Pea gravel is a small, rounded stone that provides a clean, natural look while offering decent impact absorption.

Pros:

• Inexpensive

• Excellent drainage

• Doesn’t compact as quickly as mulch

Cons:

• Not suitable for toddlers or ADA compliance

• Can pose a choking hazard

4. Poured-in-Place Rubber (PIP)

Best for: Commercial playgrounds and custom designs

This is a two-layer rubber surface that is poured and cured on-site, providing a seamless, low-maintenance solution.

Pros:

• Highly durable and ADA-compliant

• Customizable in color and design

• Requires no loose fill maintenance

Cons:

• High installation cost

• Needs professional installation

5. Artificial Grass with Foam Padding

Best for: Residential backyards and themed playgrounds

Synthetic turf combined with a shock-absorbing foam pad can provide both safety and aesthetic appeal.

Pros:

• Clean and visually appealing

• Comfortable for barefoot play

• Good drainage and low maintenance

Cons:

• Moderate cost

• May retain heat in sunny areas

6. Sand

Best for: Traditional-style playgrounds

Sand is a long-standing choice for swing set bases, especially for casual or temporary play areas.

Pros:

• Low cost

• Easy to replace and maintain

• Provides some fall cushioning

Cons:

• Can get messy and attract animals

• Needs raking and replenishing

7. Wood Chips or Bark Mulch

Best for: Natural settings and eco-conscious projects

Unprocessed wood chips or bark mulch offer a rustic look and reasonable cushioning for swings.

Pros:

• Inexpensive and natural

• Readily available

• Easy to install

Cons:

• Not ADA-compliant

• Decomposes and can become slippery when wet

How to Choose the Right Material

To determine the best material for your swing set area, consider the following:

• Safety Ratings: Look for materials that meet ASTM standards for impact attenuation.

• Compliance Needs: If accessibility is required, choose ADA-compliant options like PIP rubber or EWF.

• Budget: Factor in both installation and long-term maintenance costs.

• Location & Climate: Choose materials that drain well and hold up in your environment.

• Aesthetics: Match the style of your playground or backyard.
