Before you fall for the color, neighbor, let's talk about how tall it ought to be.* > **The quick answer:** For most window seats a 3 or 4 in (7.5 or 10 cm) cushion is right: 3 in gives a neater, lower profile under a sill, and 4 in gives more cushioning. Every extra inch raises the seat and eats window height, so measure the finished bench top first, then add the thickness to the platform height. ![Mustard ochre corduroy window seat cushion with box edge on a white paneled bench, knit and linen pillows and old books](https://cushionguide.com/media/window-seat-cushions/mustard-ochre-corduroy-window-seat-botanical-books-1600.webp "Ochre cord brings a sunny, retro note to a white window seat while cream pillows keep it soft.") ## Why this cushion looks comfortable before anyone sits Some cushions look comfortable from across the room before anybody tries them. This is one. It fills the whole ledge, wall to wall, and stands about a hand tall. On a narrow seat that reads generous without crowding the window. The top of the cushion still sits well below the sill, so the books standing up on it have room, and so would your elbows. The color is mustard ochre in [corduroy](https://cushionguide.com/fabrics/corduroy/), and that is a bold choice. The ribs split the yellow into thin stripes of light and shadow, which gives it a velvety depth instead of a flat yellow. Nothing else loud sits nearby. The pillows are a cream chunky knit and an oatmeal linen, with the flat linen in front so the pair doesn't bulk up. The botanical books are faded, the framed print is sepia, and the only color allowed to argue with the ochre is the pothos in its terracotta pot. Here is the proportion lesson hiding in the picture. Pillows against the wall take inches off the depth you can actually sit in; a backrest cushion alone takes roughly 3 in (7.5 cm). On a shallow [window seat cushion](https://cushionguide.com/cushions/window-seat-cushions/), fewer pillows and a slimmer cushion keep it a seat rather than a shelf. On my grandmother's porch the best seat was the one where your feet touched the boards and your back touched the wall. A window seat is no different. How deep is yours, front edge to wall? ## Pinned by Rosa Five spots on the plate where color and proportion are doing the work. 1. **Ochre cord seat**: Ribs break flat yellow into light and shadow for a velvety depth. 2. **Cream knit pillow**: Nothing saturated sits near the mustard, so it stays the hero. 3. **Oatmeal linen pillow**: A flat weave in front of the knit keeps the pillow pair from bulking up. 4. **Botanical books**: Faded covers match the sepia print and the mellow tone of the seat. 5. **Pothos**: One living green is the only color allowed to compete with ochre. ## Four numbers before you pick a thickness 1. **Measure the finished bench top**: Not the floor space and not the carpenter's plan. The top can differ from the room, so measure once the bench is built. 2. **Measure the room under the sill**: From the bench top to the underside of the sill or trim. A 3 in cushion suits tight spots, such as a 15 in (38 cm) gap below a sill. 3. **Add thickness to platform height**: Platform plus cushion gives the finished seat height, minus a little settle once you sit. The [seat height calculator](https://cushionguide.com/studio/seat-height-calculator/) does the sum. 4. **Take the back pillows off the depth**: A backrest takes roughly 3 in (7.5 cm) off the usable depth. Standard backs are 16 in (40 cm) tall and made as long as the seat. ## The window seat that didn't exist yet A homeowner wrote to the workshop before the carpenter had built a thing. They sent room measurements and asked for a budget figure for one seat cushion, three backrests and two armrests. The workshop gave an estimate piece by piece and added one warning: the final bench top size would be needed before cutting, because it can differ from the floor space. That warning is the whole lesson. Frames, trim and overhangs change the numbers between the plan and the wood, and walls are seldom square. Get a price early if it helps you plan, but order the cushion after the bench is built and measured. Our [thickness Pattern](https://cushionguide.com/guides/window-seat-cushion-thickness/) will be waiting. ## Buyer questions **A common question:** Can you make a one-piece L-shaped seat cushion with backrests for our dining nook? **The workshop's answer:** Yes, L-shaped seat and back cushions are made regularly. Send a sketch measuring both runs of the L, corner to corner, and say whether any part is angled. Add a photo of the nook and a picture of the backrest style you like, and the workshop will quote. **A common question:** Is the backrest as long as the seat cushion, and how tall is it? **The workshop's answer:** Yes, the seat and backrest are made the same length, so a 59 in (150 cm) seat comes with a 59 in back. The standard backrest is 16 in (40 cm) tall and can be made taller. Round armrests are made 4 in (10 cm) shorter than the seat depth. **A common question:** What thicknesses do you make, and which would you pick for a window seat? **The workshop's answer:** The standard thicknesses are 2, 3, 4 and 5 in, all at the same price. Most buyers choose 3 or 4 in: 3 in gives a neater, lower profile on a window seat, and 4 in gives more cushioning. > A window seat cushion 3 in thick sits neat under a tight sill, and 4 in feels plusher. Every extra inch raises the seat and eats window height. > > — Rosa > **Tailor's margin:** Count your pillows as inches. A backrest cushion takes about 3 in off the seat depth, so a shallow window seat wants fewer pillows and a slimmer cushion. ## On the cutting table | | | |---|---| | Cushion | Window seat box cushion, wall to wall | | Fabric | Corduroy in mustard ochre | | Thickness | 3 in (7.5 cm) for a neat line, 4 in (10 cm) for plush | | Standard options | 2, 3, 4 and 5 in (5 to 12.5 cm) | | Backrests | Same length as the seat; 16 in (40 cm) standard height | | Armrests | Round, 4 in (10 cm) shorter than the seat depth | | Pillows | Cream chunky knit and oatmeal linen, flat weave in front | | Order when | After the bench is built and measured | | Best for | A sunny [reading nook](https://cushionguide.com/cushions/reading-nook-cushions/) with a shallow seat | ## Questions buyers ask next ### What is the thinnest standard window seat cushion? 2 in (5 cm) is the thinnest standard thickness. It suits a bench that already sits high, where a thicker cushion would push the seat toward the sill. Write any other thickness you need in the order note. ### How much does a cushion sink when you sit on it? A little. Platform height plus cushion thickness gives the finished seat height, minus some settle: a 3 in cushion may ride about 2 1/2 in under you. Allow for that when the seat has to clear a sill. ### Does corduroy look different from different angles? Yes. Corduroy shades with the nap, much like velvet, looking lighter one way and richer the other. Every panel of a cushion should be cut with the ribs running the same way, or the pieces read as two colors. ### When should I order cushions for a new built-in window seat? After the carpenter finishes. The bench top can differ from the floor plan, so measure the finished top wall to wall at the back, the middle and the front, and give the smallest width. ## Related at the atelier - [Window Seat Cushion in Taupe Corduroy: Mistakes to Avoid](https://cushionguide.com/readings/taupe-corduroy-window-seat-built-in-bookcase/): A window seat cushion that runs into a bookcase should be measured to the shelf upright and cut slightly under size so it slides in without buckling. - [Window Seat Cushion Thickness: Dusty Rose Corduroy at Golden Hour](https://cushionguide.com/readings/dusty-rose-corduroy-window-seat-cushion-golden-hour/): Size a window seat cushion's thickness to the bench, not to habit: the standard is 4 in (10 cm), 3 in gives a lower, neater seat, and 6 or 6.5 in has been made on request for deep lounging. - [Corduroy Window Seat Cushion With Bolsters: a 98-Inch Nook](https://cushionguide.com/readings/mustard-gold-corduroy-window-seat-ivory-sage-pillows/): A long corduroy window seat cushion becomes a daybed-style reading nook with three additions: a thick seat, bolsters at the ends and a slim back cushion. - [Window seat cushion thickness compared: 2, 3, 4 and 5 inches](https://cushionguide.com/guides/window-seat-cushion-thickness/): Most window seat cushions should be 3 or 4 in (7.5 or 10 cm) thick. - [Window seat dimensions and the cushion sizes that fit them](https://cushionguide.com/guides/window-seat-dimensions/): Typical window seat dimensions are 18 to 24 in (46 to 61 cm) deep, 36 to 72 in (91 to 183 cm) wide and 16 to 21 in (41 to 53 cm) high to the top of the cushion, about 18 in on average. - [How thin can a window seat cushion be so the window still opens?](https://cushionguide.com/answers/thin-window-seat-cushion-under-windowsill/): A window seat cushion can be made as thin as 3/4 in (2 cm), but 2 in (5 cm) is the thinnest recommended for sitting. - [Reading nook bolsters, back pillows and a seat depth that invites a nap](https://cushionguide.com/guides/reading-nook-cushion-bolsters/) *Porch light's on — Rosa* --- Written by Rosa Delgado (https://cushionguide.com/masters/rosa/) for CushionGuide (https://cushionguide.com/about/).
