Decide who owns it before you order, partner, and the rest is arithmetic.* Also asked as: Can they be connected, or two separate cushions?; Easier to do 2 pieces instead of a large L? > **The quick answer:** Order an L-shaped or U-shaped banquette as separate straight cushions, one per run, and subtract the corner. The short cushion is the total run minus the depth of the long cushion that sits in the corner, so a 61 in (155 cm) run beside a 19 in (48 cm) deep cushion needs about 42 in (107 cm). Piping comes as standard. ![Dove gray chenille seat and back cushions on an oak L-shaped corner banquette with teapot and croissants on a round table](https://cushionguide.com/media/l-shaped-cushions/gray-chenille-oak-corner-banquette-breakfast-nook-1600.webp "Soft gray chenille lets the oak and the morning light supply the warmth in this beadboard breakfast corner.") ## Key facts - L and U banquettes are ordered as separate straight cushions, one per run. - Separate pieces are easier to handle and sit neater than one L-shaped piece. - Short-side length = total run minus the depth of the cushion that owns the corner. - Piping (welting) is standard on banquette cushions. - Box cushions with top and bottom piping and hidden back-edge zippers are available, with high-density foam. - One banquette set took about 1-2 weeks of production; ask for your own timing in writing. - Very large banquettes may be split into more pieces; send measurements first. ## Three follow-ups, in the order buyers send them **Can the L be one connected cushion?** For large sizes, two straight pieces. They're easier to handle and sit neater against two walls than one bent slab. **So I just measure each wall?** Almost. Give the corner to one cushion and take its depth off the other, or one piece ends up too long. **And a U?** Same rule at both corners. The [U-shaped banquette Pattern](https://cushionguide.com/guides/u-shaped-banquette-cushions/) walks all three runs; [L-shaped cushions](https://cushionguide.com/cushions/l-shaped-cushions/) shows finished corners. ## The corner sum 1. **Measure both runs into the corner**: Tape along the back wall of each run, all the way in. 2. **Give the corner to one cushion**: Usually the long one. Note its depth: say 19 in (48 cm). 3. **Subtract**: Short cushion = short run − that depth. 61 − 19 = 42 in (107 cm). 4. **Write every piece in full**: Length x depth x thickness and a fabric code per piece. The [bench cushion builder](https://cushionguide.com/studio/bench-cushion-builder/) helps. ## The 61-inch cushion that should have been 42 A buyer sent the runs of an L-shaped bench and asked for the short side at its full 61 in (155 cm). The long cushion, 19 in (48 cm) deep, already filled the corner. The two would have fought over the same square; with the corner sum, the short piece became about 42 in (107 cm). > **Tailor's margin:** For an L-shaped bench, the short cushion equals the short run minus the long cushion's depth: 61 in minus 19 in is about 42 in, not 61. ## Buyer questions **A common question:** For an L-shaped bench, should the cushion be one connected piece or two? **The workshop's answer:** For large sizes, two separate cushions work better: easier to handle, neater to sit. One buyer ordered 70 x 18 in and 102 x 18 in. Subtract the overlap where the pieces meet in the corner, or one ends up too long. **A common question:** How do I order cushions for a U-shaped banquette with welting? **The workshop's answer:** Order each cushion at its own size, for example two sides at 63.5 x 21.5 in (161 x 55 cm) and a back at 93.5 x 21.5 in (237 x 55 cm), 2 in thick, with your fabric code. Welting is standard. **A common question:** Can you make L-shaped banquette box cushions with hidden zippers and piping on both edges? **The workshop's answer:** Yes. Box-style seat and back cushions come with piping, hidden zippers and high-density foam in performance fabrics, olive and moss greens included. A 4-piece set took 1-2 weeks of production. ## Questions buyers ask next ### Which cushion should own the corner of an L-shaped bench? Usually the long one. Let the long cushion run into the corner, then shorten the other by its depth. Either way works, as long as only one cushion claims the corner square. ### Can very long banquette runs be one cushion? Very large banquettes may need more pieces. Send your measurements first and the workshop will say how to split the order into straight lengths that are easy to handle. ### Where does the zipper go on a banquette cushion? On box-style banquette cushions the hidden zipper sits on the back edge, against the wall, with piping on the top and bottom edges. Piping is standard on banquette sets. ## Related at the atelier - [L-Shaped Bench Cushion as Two Pieces for an Oak Breakfast Nook](https://cushionguide.com/readings/taupe-leaf-print-corner-nook-cushions-craftsman-oak/): An L-shaped bench cushion is usually best ordered as two straight cushions that butt together at the corner, each with its own measured size. - [L-Shaped Bench Cushion Orders: a Slate Blue Nook From Above](https://cushionguide.com/readings/slate-blue-linen-l-shape-banquette-overhead/): To order an L-shaped bench cushion right the first time, send a photo from above, a sketch with both runs labeled and measured, the fabric by its number, and a note saying which seat runs into the… - [L-Shaped Bench Cushion in Denim Velvet for a Two-Window Corner](https://cushionguide.com/readings/denim-blue-velvet-corner-bench-two-windows/): For an L-shaped bench cushion that seats a crowd, order two separate seats, one short and one long, that butt together in the corner instead of one L piece; each lifts and re-covers on its own. - [How do I measure an L-shaped bench so the corner cushions don't overlap?](https://cushionguide.com/answers/l-shaped-bench-cushion-measurements-corner/): Measure each arm of the L from the back corner to its end, plus the seat depth, and the workshop shortens one cushion by that depth so the two butt together without overlapping. - [What measurements do you need for an L-shaped bench with back cushions?](https://cushionguide.com/answers/measure-l-shaped-bench-cushions-backrest/): For an L-shaped bench cushion, send the end-to-end length of each leg of the L, the seat depth and thickness, and a sketch or photo, and say if any part is angled and if you want backrests. - [Which piece owns the corner?
