Description

Half-round cushions combine a straight side with a smooth curve, which makes generic covers bunch at the corners or pull unevenly along the curved edge. Custom half-round cushion covers are patterned to follow that straight edge and arc precisely, so the cover lays flat, aligns with your bench or seat, and looks made-to-measure.

You’ll measure the straight edge, the widest span across the curve, and the thickness of the cushion. If the curve is very tight or very shallow, mention that in your notes and share photos or a quick sketch. This helps ensure the custom outdoor cushion covers or indoor covers replicate the exact half-moon profile you have.

Why choose custom half-round cushion covers?

  • Purpose-built for semicircles: No more forcing round or rectangular covers to fit a half-moon cushion.

  • Flexible placement: Works for indoor benches, bay windows, banquettes, and outdoor semicircular seating.

  • Durable, easy-care fabrics: Designed to handle everyday use and simple cleaning routines.

Fabrics information

Half-round cushion covers often live in high-impact visual spots—entry benches, bay windows, or unique patio benches. Waterproof Horizon is ideal if the cushion sits near doors, pools, or humid areas, while breathable Canvas is a great choice for indoor nooks and covered seating. Both options resist stains, wear, and UV damage, and come in a range of colors for cohesive styling with surrounding couch cushion covers or décor.

Feature highlights

  • Tailored for half-round, half-moon, and semicircular cushions.

  • Built to your straight edge length, curved edge span, and cushion thickness.

  • Offered in Sunbrella Horizon (waterproof vinyl) or Sunbrella Canvas (breathable acrylic).

  • UV-, fade-, mold-, and mildew-resistant performance fabrics.

  • YKK zipper closure for easy removal and refitting.

  • 5-year warranty on fabric color and strength, with Horizon’s additional 3-year pinking warranty.

Frequently Asked Questions

Measure the straight edge from end to end, then measure across the widest part of the curve (from one side of the arc to the other). Finally, measure the cushion thickness. A quick sketch showing straight and curved edges, plus a few photos, helps lock in the exact shape.
If the corners flow smoothly into the main curve, you can describe it as a single continuous curve. If the corners have a distinct radius or different curve, note that in the order comments and include photos so the pattern accounts for those details.
For most indoor bay window applications, Sunbrella Canvas is ideal because it’s breathable, soft, and still resistant to stains and fading from sunlight. Horizon is more appropriate if the area gets a lot of moisture or acts like an indoor–outdoor transition zone.
Yes, when cut to the correct measurements and supported by quality foam, the cover is designed to maintain its profile. Horizon offers slight stretch, which can help with a smooth fit, while Canvas relies more on an accurate pattern and consistent support.
Yes, dry fast foam can be added for outdoor use, giving you a full cushion and cover solution that drains quickly after rain or cleaning.

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.

Easy to Maintain and Clean

These chair covers have done an excellent job resisting dust and pollen. The grommets make securing them simple and the fabric still looks new after months outdoors.

Protects Completely in All Seasons

The water repellent surface works exactly as described. The cover tightens neatly with the drawstring and protects the grill from rust and debris. The design feels well planned and very practical.

Highly Reliable Weatherproof Cover

The grill cover feels heavy duty without being stiff. It stays secure during storms and the color remains rich even under full sun. The order arrived earlier than expected which was a pleasant bonus.

Dependable in Rain or Shine

This grill cover arrived quickly and feels extremely well made. The material repels rain effortlessly and the drawstrings keep it steady during strong winds. My grill looks spotless every time I uncover it.
