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.\u003c\/p\u003e\n\u003cp\u003eGetting 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.\u003c\/p\u003e\n\u003cp\u003eMarine 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.\u003c\/p\u003e\n\u003cp\u003ePairing the curve with straight seating?

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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch2\u003eFeature Highlights\u003c\/h2\u003e\n\u003cp\u003e• Straight back edge, elongated curved front — patterned as the true shape\u003c\/p\u003e\n\u003cp\u003e• Curve drafted from three depth measurements, not eyeballed\u003c\/p\u003e\n\u003cp\u003e• Marine-friendly Sunbrella Horizon vinyl or woven Sunbrella Canvas\u003c\/p\u003e\n\u003cp\u003e• Fits curved benches, bay alcoves, boat seats, and half-moon stools\u003c\/p\u003e\n\u003cp\u003e• Boxed side wall follows the arc without puckering\u003c\/p\u003e\n\u003cp\u003e• YKK zipper along the straight back edge, hidden against the wall or gunwale\u003c\/p\u003e\n\u003cp\u003e• 5-year limited warranty on both fabric options\u003c\/p\u003e","brand":"ZIPCovers","offers":[{"title":"Default Title","offer_id":51007290736807,"sku":"semi-oval-cushion-cover","price":20.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/6260\/5223\/files\/CustomSemiOvalCushionCover-v2_1.webp?v=1784776056","url":"https:\/\/zipcovers.com\/products\/semi-oval-cushion-cover","provider":"ZIPCovers","version":"1.0","type":"link"}
