Outdoor cushions play a crucial role in transforming UK gardens, patios, and summer seating areas into comfortable, inviting spaces. Whether you’re refreshing a rattan corner sofa, upgrading a wooden bench, or replacing tired sun lounger pads, choosing the right outdoor cushion foam determines how well your seating performs through our unpredictable British weather.
Many homeowners struggle with cushions that stay wet for days, grow mildew, flatten quickly, or simply don’t feel comfortable - especially when cheaper sponge like foams absorb water like a sponge.
This guide is designed to help you understand the best outdoor cushion foam options available in the UK, how to measure accurately for replacements, and how to choose materials that stay comfortable, durable, and weather ready all summer long. Using insights from real customer questions, UK climate considerations, and industry leading foam technologies, we’ll walk you through everything you need to know before ordering new outdoor cushions.

What Makes a Great Outdoor Cushion
Before diving into foam types, it helps to understand what makes an outdoor cushion perform well in the UK climate. Great cushions share a handful of qualities that determine how comfortable, durable, and weather ready they’ll be once they’re out on the patio.
- Comfort: Long lasting support without sagging or bottoming out.
- Durability: Resistance to daily use, UV exposure, and seasonal humidity.
- Support: Correct density prevents sinking into the frame.
- Weather Performance: Quick drying, mould resistant foam is essential.
- Aesthetic Structure: Quality foam maintains crisp edges and tailored shape.
- Practicality: Removable covers, washable fabrics, and breathable foam improve longevity.

How to Measure for Outdoor Cushion Foam
Accurate measurements are the foundation of a perfect outdoor cushion. Whether you’re replacing old pads or ordering bespoke foam cut to size, taking the time to measure properly ensures your new cushions fit beautifully and perform exactly as intended.
Tools You’ll Need
- Rigid metal tape measure
- Pencil and paper
- Optional: brown paper for tracing curved or tapered frames
- A clear, empty furniture frame (remove old cushions first).
Step by Step Guide
1. Measure Width (Left to Right) - Measure across the inside of the frame at the front, middle, and back. Use the narrowest measurement.
2. Measure Depth (Front to Back) - Measure from the front lip to the backrest. Subtract 1cm to prevent overhang.
3. Measure for Seat + Back Cushion Sets - If the back cushion rests on top of the seat cushion:
3.1 Measure total backrest height
3.2 Subtract seat cushion thickness
If the seat cushion pushes fully to the back frame:
3.3 Measure total seat depth
3.4 Subtract back cushion thickness
4. Measure Curved, Tapered, or Irregular Shapes - Trace the frame onto brown paper, cut it out, test the fit, and send the template to Foam & Covers.
Additional Tips
- Never measure old cushions - they sag and distort.
- Measure to the nearest 0.5cm.
- Ensure cushions are sized for comfortable seat height.
- For long cushions over 107 inches, consider splitting into sections.
