{"product_id":"triangle-cushion-cover","title":"Triangle Cushion Cover","description":"\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eA triangle cushion is a lean, not a seat. Prop it against a wall, a daybed frame, or a headboard and the sloped face turns flat lounging furniture into reading-and-recline furniture. The catch is that the angle only works if the cover preserves it — and a custom triangle cushion cover is cut from your cushion's exact three numbers, so the profile that fits your back keeps fitting it.\u003c\/p\u003e\n\u003cp\u003eThree measurements describe the entire shape: the height of the vertical back, the width of the base from front to rear, and the length of the run. Those first two set your recline angle — a tall, short-based triangle sits steep for upright reading; a low, long-based one lies shallow for a gentle recline. Whatever geometry your foam carries, the cover reproduces it.\u003c\/p\u003e\n\u003cp\u003eWedges also live hard lives — dragged to the pool edge, propped on grass, leaned on for whole afternoons. A waterproof triangle cushion cover in Horizon keeps all of that on the surface, and when the original fabric gives up, a replacement triangle cushion cover renews the shaped foam for a fraction of what a new wedge costs.\u003c\/p\u003e\n\u003cp\u003eThe wedge usually leans against something bigger — explore every cover shape in the collection and outfit the daybed behind it too.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy Choose Our Custom Triangle Cushion Covers?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Triangle Is the Side View\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis shape is all profile: vertical back, flat base, one long slope. The two triangular side panels are cut as an identical pair from your height and width, which is what keeps that profile crisp instead of drifting soft.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOne Clean Slope to Lean On\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe hypotenuse face is a single panel — no seam crossing the surface your back actually uses. It pulls taut from the top edge to the base, so the recline feels smooth end to end.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA Point That Stays a Point\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhere the slope meets the base, the foam narrows to almost nothing — the spot cheap covers ball up and round off. A sewn seam runs that meeting edge instead, holding the wedge's sharp front line.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Recline Sun Can't Bleach\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA sloped face catches more direct sun than any flat cushion around it. Solution-dyed fabric holds its color through that exposure, and Horizon's waterproofing keeps surprise showers out of the foam.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLoading Happens Along the Base\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe zipper spans the base's rear edge, where the opening is widest and the hardware is invisible.

The cover is built from that profile — two triangular side panels cut as a matched pair, a back panel at your height, a base panel at your width, and the slope face spanning between them, all running your stated length. Get the two side triangles identical and the slope lies flat; that is the entire craft of this shape.\u003c\/p\u003e\n\u003cp\u003eThe slope is the working surface — it is what backs lean against and legs rest on — so the fabric face matters more here than on a cushion that only gets sat on. Sunbrella Horizon brings the marine-grade, fully waterproof vinyl for wedges that live on open patios and pool decks; Sunbrella Canvas brings the softer woven acrylic for shaded lounges where the wedge touches bare skin for an hour at a time. Both carry Sunbrella's 5-year limited warranty.\u003c\/p\u003e\n\u003cp\u003eThe zipper hides along the rear of the base — the one face that never shows and never gets leaned on. Corrosion-resistant YKK coil under a flap, so the hardware outlasts the seasons the wedge spends outside.\u003c\/p\u003e\n\u003ch2\u003eFeature Highlights\u003c\/h2\u003e\n\u003cp\u003e• A leaning wedge with a true triangle profile — vertical back, sloped front, pointed meeting edge\u003c\/p\u003e\n\u003cp\u003e• Three order fields: height up the back, width along the base, length down the run\u003c\/p\u003e\n\u003cp\u003e• Waterproof Sunbrella Horizon vinyl or woven Sunbrella Canvas\u003c\/p\u003e\n\u003cp\u003e• Works as a backrest wedge, recline support, and leg-elevation cushion\u003c\/p\u003e\n\u003cp\u003e• Triangular side panels cut as a matched pair, so the profile stays true\u003c\/p\u003e\n\u003cp\u003e• Corrosion-resistant YKK zipper set along the base, under the cushion\u003c\/p\u003e\n\u003cp\u003e• 5-year limited fabric warranty across both fabrics\u003c\/p\u003e","brand":"ZIPCovers","offers":[{"title":"Default Title","offer_id":51007290900647,"sku":"triangle-cushion-cover","price":31.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/6260\/5223\/files\/TriangleCushionCover.webp?v=1785145501","url":"https:\/\/zipcovers.com\/products\/triangle-cushion-cover","provider":"ZIPCovers","version":"1.0","type":"link"}
