Outdoor Rocker Cushions: What Size and Thickness Should You Buy?

Nothing says relaxation like gently rocking on your porch or patio with a cup of coffee in hand. But if your rocking chair doesn’t have the right cushion, it’s likely not as comfortable—or stylish—as it could be. Choosing the proper size and thickness for your outdoor rocker cushions is key to getting the most out of your outdoor seating.

At Cushions by Wicker Imports, we specialize in high-quality custom outdoor cushions designed to bring comfort and longevity to your outdoor furniture. In this post, we’ll guide you through everything you need to know about selecting the right size and thickness for your outdoor rocker cushions.

1. Start with Accurate Measurements To ensure your rocker cushion fits perfectly, start by measuring your chair:

  • Seat Width: Measure between the widest points of the seat frame.
  • Seat Depth: Measure from the front edge of the seat to where it meets the backrest.
  • Back Height: If you’re replacing a full set, measure from the seat to the top of the chair’s back.

Be sure to account for curved or tapered frames—sometimes a template or photo helps with custom cushion orders.

2. Know Standard Sizes (But Don’t Be Afraid to Go Custom) While some outdoor rockers follow standard dimensions, many have unique shapes and sizes. At Cushions by Wicker Imports, we recommend custom-sized cushions to ensure a proper fit, especially for antique or uniquely shaped rocking chairs.

Typical cushion dimensions for outdoor rockers might be:

  • Seat cushions: 19″ to 23″ wide, 18″ to 20″ deep
  • Back cushions: 20″ to 26″ tall, matching the seat width

If you’re unsure, our team can help you measure or even create a custom template.

3. Pick the Right Thickness The thickness of your cushion can make a huge difference in comfort and support. Here’s a general guide:

  • 2″–2.5″ thick: Sleek look, suitable for short-term use or decorative accent chairs
  • 3″–4″ thick: Balanced comfort and style, ideal for everyday use
  • 5″+ thick: Plush and luxurious; perfect for extended lounging or ergonomic support

For rockers, we typically recommend 3″ to 4″ thick seat cushions for optimal comfort without compromising posture.

4. Consider Cushion Style and Construction Choose between single-piece cushions (seat + back combined) or two-piece sets. Two-piece sets offer more flexibility and often fit better. You’ll also want to consider whether you want ties or Velcro straps to keep cushions in place—especially important on windy patios.

5. Don’t Forget the Fabric and Fill Outdoor rocker cushions should be made from weather-resistant materials like solution-dyed acrylic (e.g., Sunbrella®), olefin, or treated polyester. These fabrics resist fading, mildew, and moisture. For fill, quick-dry foam or polyfill wrapped in a water-resistant liner will extend the cushion’s lifespan.
