Somewhere between a rectangle and a half-circle lives the semi oval — the shape curved benches, bay window alcoves, and boat seats actually use. It's flat where it mounts and gracefully arced where it shows, and it is thoroughly unbuyable off a shelf. A custom semi-oval cushion cover is drafted from your cushion's own straight edge and curve depths, so the arc you get is the arc you have.
Getting the curve right changes how the whole seat reads. A too-flat cover leaves empty fabric flapping at the arc's crown; a too-deep one pulls the cushion's nose up like a boat planing. Three depth measurements pin the real curve, and the finished cover lies flat from the straight edge to the farthest point of the arc.
Marine or garden, the working conditions argue for serious fabric — a waterproof semi oval cushion cover in Horizon for spray and rain, or Canvas under cover — and when the original upholstery fades, a replacement semi oval cushion cover renews shaped foam that would cost real money to recut.
Pairing the curve with straight seating? Shop every shape in the outdoor cushion covers collection and keep the fabrics identical across both.
Why Choose Our Custom Semi-Oval Cushion Covers?
An Arc Drafted, Not Guessed
Center depth plus two quarter-point depths describe your exact curve — shallow crescent or full bow. The pattern reproduces it, so the cover's arc and the foam's arc are the same arc.
Flat Against the Wall, Full at the Front
The straight edge squares up against whatever it mounts to; the curve carries all the shaping. Each edge is engineered for its own role, which is what the shape demands.
Spray-Zone Approved
Boat seats and poolside curves live in mist and splash. Marine-grade Horizon treats that as home turf — waterproof, salt-tolerant, and cleaned with a rag in the time it takes to dock.
A Side Wall That Rounds the Bend
Boxed walls love straight lines and fight curves — unless they're eased in properly. Ours follow the arc without gathering, keeping the cushion's profile clean at eye level.
Shaped Foam Deserves a Second Act
Curved foam is cut, not stamped, and it's priced that way. Re-covering it in warranty-backed fabric extends the investment for a fraction of what new shaped foam would run.
Step-by-Step Measuring Guide
• Strip the old cover off and set the bare foam down with the straight edge toward you.
• Measure the straight back edge end to end.
• Measure the depth from the straight edge to the farthest point of the curve, at the center.
• Take the same depth reading at the quarter points, left and right of center.
• Finish with the thickness at the side wall, then read all five numbers back off the foam one final time.
A semi-oval is a curve with a job: the straight edge mounts against a wall, a bay window, or a boat's transom, while the elongated arc faces the room or the deck. Drafting that arc accurately takes more than a width — we pattern from the straight-edge length plus depth readings at the center and both quarter points, which captures how shallow or full your particular curve runs. The boxed side wall is then eased around the arc so the fabric follows it smoothly, without the puckering that betrays a forced fit.
The boat connection is real for this shape — semi oval cushions, top stern benches, and helm seats constantly — and it sets the fabric bar. Horizon is marine-grade vinyl in the literal sense: waterproof, unbothered by spray, and wipeable after a day of sunscreen and salt air. Canvas suits the landside versions — curved garden benches and bay alcoves — with its softer woven face and the same solution-dyed permanence. Sunbrella's 5-year limited warranty covers both.
The zipper runs the straight back edge, which in most installations faces a wall or gunwale — so the hardware is hidden by the furniture's own position. Corrosion resistance still matters near water, and the YKK coil delivers it.

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