Length and height are easy; the taper — a bottom width and a smaller top width — is what makes the cushion stand up straight against the frame instead of flopping. Enter all four and the cover comes back matching the cushion's real profile — straight back, sloped front, flat top.\u003c\/p\u003e\n\u003cp\u003eThese back cushions do quiet, constant work: the backrest line on a daybed, the support run along a bench, the padded rail across a swing. They face the sun square-on all afternoon — the exact exposure that bleaches cheap fabric fastest. Solution-dyed Sunbrella holds its color there, because the pigment lives in the fiber rather than on the surface.\u003c\/p\u003e\n\u003cp\u003eAnd when the old fabric finally gives out, a replacement bolster straight back cushion cover costs a fraction of new cushions. The shaped foam inside is almost always still good. Re-cover it and the whole daybed line looks new again.\u003c\/p\u003e\n\u003cp\u003eRe-covering the seat cushions at the same time?

The top is flat and narrower than the bottom, and the difference between top width and bottom width is exactly what sets that lean angle. We cut the two end profiles as a matched pair from your four numbers, so the angle you measured is the angle you get.\u003c\/p\u003e\n\u003cp\u003eExposure picks the fabric. Sunbrella Horizon, a marine-grade vinyl, suits back cushions on uncovered daybeds and swings: fully waterproof, wiped clean in seconds, flexible enough to follow the rounded top without stress lines. Sunbrella Canvas — solution-dyed acrylic, water-repellent and breathable — is the softer choice against shoulders on covered porches. Both carry Sunbrella's 5-year limited fabric warranty.\u003c\/p\u003e\n\u003cp\u003eThe YKK zipper runs along the bottom edge, where the cushion sits against the seat — invisible in use, shielded from sun and rain by the cushion's own footprint, and corrosion-resistant besides.\u003c\/p\u003e\n\u003ch2\u003eFeature Highlights\u003c\/h2\u003e\n\u003cp\u003e• A straight-backed support wedge — vertical at the rear, angled lean at the front, sewn to your four numbers\u003c\/p\u003e\n\u003cp\u003e• Length, height, bottom width, and top width all cut to the quarter inch\u003c\/p\u003e\n\u003cp\u003e• Flat top narrower than the base — the taper that gives the lean its angle\u003c\/p\u003e\n\u003cp\u003e• Waterproof Sunbrella Horizon vinyl or soft-woven Sunbrella Canvas\u003c\/p\u003e\n\u003cp\u003e• Backs daybeds, benches, swings, and cylindrical outdoor loungers\u003c\/p\u003e\n\u003cp\u003e• YKK zipper tucked along the bottom edge, hidden where cushion meets seat\u003c\/p\u003e\n\u003cp\u003e• 5-year limited fabric warranty, both fabric lines\u003c\/p\u003e","brand":"ZIPCovers","offers":[{"title":"Default Title","offer_id":51007290048679,"sku":"bolster-straight-back-cushion-cover","price":27.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/6260\/5223\/files\/CustomBolsterStraightBackCushionCover-v2_1.webp?v=1784775349","url":"https:\/\/zipcovers.com\/products\/bolster-straight-back-cushion-cover","provider":"ZIPCovers","version":"1.0","type":"link"}
