Description

Curved cushions highlight every fitting flaw—gapping at the back, folds at the corners, or a cover that never quite follows the arc. Custom curved cushion covers are cut and sewn to mirror your actual curve, so the fabric lays smooth and looks intentional from end to end.

Provide the straight segments (if any), the width of the cushion, the depth of the curve (or radius, if known), and the thickness. From there, a pattern is created that follows your curve exactly. You can upload photos or a sketch, and support is available if you’re unsure how to describe or measure the shape for your custom cushion covers.

Choose Sunbrella Horizon when the curved cushion sits in a high-moisture or marine-like environment, or go with Sunbrella Canvas if the seating lives on a covered porch, breakfast nook, or indoor–outdoor space where breathability matters. Both fabrics offer strong UV protection, durability, and long service life.

Optional: Add dry fast foam inserts for a complete cushion upgrade. This quick-drying foam is ideal for custom outdoor cushion covers on curved benches and built-ins.

Why choose custom curved cushion covers?

  • Made for complex curves: Works for gentle arcs, semi-circles, and multi-segment curves where straight covers simply don’t sit right.

  • Environment-ready fabrics: Waterproof Horizon for exposed, wet, or coastal areas; breathable Canvas for covered patios and interiors.

  • Easy to use and maintain: YKK zippers simplify removal for cleaning, and performance fabrics resist everyday wear.

Fabrics information

Select your material during the customization process:

Sunbrella Horizon (Marine-grade waterproof vinyl)

  • This engineered synthetic features a knit polyester backing that provides exceptional four-way stretch, making it ideal for following curved profiles without creating tension lines or fabric stress points.

  • The proprietary topcoat stays cool even in direct sunlight and offers remarkable softness compared to traditional marine vinyl.

  • Resists cold-cracking, making it suitable for year-round outdoor use in varying climates.

  • Bleach-cleanable for easy disinfection and maintenance without damaging appearance or performance.

  • Highly UV-stable pigments prevent fading and material degradation from continuous sun exposure.

  • 5-year warranty covering color retention and material strength, plus 3-year protection against microbial pink staining.

  • Best for: Curved boat seating, poolside furniture, coastal benches where waterproof protection is non-negotiable.

Sunbrella Canvas (Solution-dyed acrylic)

  • Made from 100% solution-dyed acrylic fibers that lock color into the material at the molecular level, delivering superior fade resistance even in tropical and high-UV climates.

  • Naturally breathable construction allows air circulation, which helps moisture evaporate quickly and prevents the trapped humidity that leads to mold growth on curved surfaces.

  • Air-dries rapidly after rain or cleaning, with minimal shrinkage or stretching over time.

  • Easy maintenance with soap and water; bleach-safe for removing stubborn stains.

  • 5-year warranty against color fading and fabric breakdown.

  • Best for: Covered patios, indoor bay window seats, breakfast nooks, and curved outdoor furniture where comfort and breathability are priorities.

Both materials come in multiple colorways for design flexibility

Frequently Asked Questions

Measure the straight edges (if any), the overall width from one end of the curve to the other, the deepest point of the curve (or radius if you know it), and the cushion thickness. A simple sketch with dimensions plus a few photos makes it very easy to build a cover that follows your exact curve.
Yes. Note the lengths of each straight segment and then measure the curved portion separately. Mention that it’s a “curved corner” or “L with a rounded end” in your order notes so the pattern can combine both straight and curved elements.
If the area is indoors or under cover and doesn’t get soaked, Sunbrella Canvas is usually the better choice because it’s breathable and comfortable for everyday sitting. If the window seat is directly exposed to rain or heavy condensation, Horizon’s waterproof vinyl may be more appropriate.
When measurements are accurate, the pattern is drafted to follow the curve, which greatly reduces excess fabric and wrinkling. Horizon’s 4-way stretch can help smooth minor measuring variances, while Canvas relies more on precise measurements for the cleanest fit.
Yes. Most curved couch cushion covers use a zipper along a straight edge or the back edge for a clean look, but you can request a specific side that works best for how you plan to remove and reinstall the cover.

Great covers, just as advertised

Great waterproof material and made to spec.

The material is good quality. The fit is not good, despite their website requiring a number of different measurements. Part of me suspects the website photos were generated by AI, as they’re almost too perfect.

Worth the money

I just received my order. I am very happy with the product.
It fits perfectly. Please let the people who created the cover know; they did a great job.
Here's a picture. I hope the material will last a long time against the sun. Just keep in mind that it does take 4-6 weeks so be very patient unlike me. haha. totally worth it

The tie downs at the corners were not long enough to latch together. Otherwise the build quality was very high.

Highly recommend!

I ordered a right arm love seat cover, left arm love seat cover and an ottoman cover in the higher end fabric. With a discount code, all 3 were a little over $300. The covers are perfect and the quality of the fabric is…..well, let’s just say it’ll probably outlive me! They’re very heavy duty and totally waterproof. Craftsmanship is excellent.

Customer service was A+. I had questions about measuring and some concerns about shipping. I used the chat option for questions about measurements and it was a REAL person, not a bot. He was friendly and personable. They also contacted me to verify some things about my measurements. When I contacted both sales and customer service via email with a question, they responded within hours. They’re constructed in another country and it took about 6 weeks from order to delivery. The delay was FedEx customs.

Bottom line, they are excellent covers at an extremely fair price that fit perfectly, will last forever and are a very friendly, responsive, competent company to work with.

Not waterproof

Not waterproof. After getting 1/2” of rain over a few hours the cushions were very wet when the cover was taken off the next day. Not sure how this happened with a “waterproof “ cover. Does not appear to be breathable as they claim. Very disappointed.

If it’s perfectly, it’s great quality, and they were quite timely.

Excellent Coverage and Finish

This grill cover has survived several storms without shifting. The material feels premium and still looks flawless after months outdoors.

Holds Up Amazingly in Weather

This grill cover sits perfectly around the edges and feels incredibly durable. Water does not linger on the surface and the handles make it simple to remove. Excellent quality.
