Equilateral triangle cushions are the solution for seating areas that standard cushions can’t cover. Their unique shape fits seamlessly into corner benches, bay windows with angled sides, and triangular dining nooks. Instead of leaving gaps or forcing a square cushion into a mismatched space, these cushions give you a tailored fit that looks intentional and feels comfortable.
We build every cushion to your dimensions, so it blends perfectly with your furniture. Whether you’re finishing a bay window, upgrading a built-in corner bench, or styling a cozy reading nook, our triangle cushions make unusual spaces practical and inviting.
Use Cases:
Our fabric range is designed to give you complete freedom in how your triangle cushion looks and feels. From soft cottons and linens to durable poly blends and textured fabrics, there are options for every interior style. Choose bold tones to make a statement, or subtle neutrals to let the shape of your space stand out.
Triangle cushions are designed for corners and spaces where standard rectangular cushions don't work. The equilateral triangle shape fits snugly into bay window corners, breakfast nook angles, and built-in bench seating without awkward gaps. Place them on hard dining benches to make long meals more comfortable, or use them to create inviting reading nooks where rectangular cushions would slide around.
Each triangle seat cushion is made to your measurements. Whether you need small corner cushions for a window seat or larger triangle bench cushions for dining seating, we build each piece to fit your space perfectly. Our triangle foam cushions use quality materials that hold their shape through daily use.
Why Choose Our Triangle Cushions?
Problem-Solving Design: Made for triangular and angled seating where standard cushions won’t fit, eliminating gaps in corner seating, bay windows, and angled benches where rectangular cushions leave empty spaces or hang over edges awkwardly.
Made to Your Space: Custom sizing ensures your triangle cushions fit your exact measurements, whether it's a tight corner window seat or a full-length dining bench with multiple triangular sections.
Quality Foam Core: High-density foam provides firm, supportive seating that won't flatten over time, while our fiberfill option offers softer comfort—both options maintain the cushion's shape through regular use.
Easy Care: YKK zippers make covers simple to remove for cleaning. Unzip, wash, air dry, and put them back on to keep your cushions fresh.
You need two measurements: side length and thickness. Measure from corner to corner along your bench for the side length. Standard thickness ranges from 2 to 6 inches, depending on your comfort preference. For multiple cushions on one bench, measure the total length and tell us how many you need. For non-equilateral corners, provide all three side measurements plus thickness.
Your fabric choice depends on where you'll use the cushions. For dining benches and breakfast nooks where spills happen, choose performance fabrics that resist stains and clean easily. For reading nooks and bedroom window seats where comfort is priority, soft velvets and chenilles feel great. Linen and cotton work well for everyday use in most spaces, offering a balance of comfort and durability. If you have kids or pets, stick with darker colors or patterns in stain-resistant fabrics. We can help you choose the right fabric based on your specific needs.
Choose 2-3 inches for decorative window seats or occasional seating, 3-4 inches for regular dining bench use, and 4-6 inches for primary seating like breakfast nooks where you spend more time. Thicker cushions provide more comfort but require deeper seating areas to maintain proper seat height.
Triangle cushions are designed specifically for corner seating and angled spaces in your home. Their equilateral shape fits perfectly into bay window corners, breakfast nook angles, and built-in bench seating where rectangular cushions leave gaps or don't sit properly. Use triangular pillows to make dining benches more comfortable for long meals, create cozy reading nooks, or complete the seating in banquettes and window seats. The triangle shape stays in place without sliding or shifting, making these cushions practical for any corner or angled seating area.
Triangle seat cushions solve fitting problems that rectangular cushions can't. In corner spaces like bay windows or L-shaped benches, rectangular cushions either leave empty triangular gaps or overlap awkwardly. Triangle cushions fill these spaces exactly, creating a complete, polished look. They also stay in position better on angled seating because their shape naturally fits the corner, while rectangular cushions tend to slide around. For dining benches and breakfast nooks with corners, custom triangle cushions provide consistent comfort across the entire seating area.
Yes, we make custom triangle cushions in any configuration. If your corner isn't a perfect equilateral triangle, send us all three side measurements and we'll create cushions that fit exactly. Right-angle triangles and isosceles triangles are also available.
I ordered these cushions last week and was told it would be a 3-4 week wait. What a surprise when they came today, about 8-9 days after I ordered them. They look amazing and look very professionally stitched. Thank you Zip Cushions, I never knew it would be this easy to order these on line. Would definitely recommend!
