# A gray basketweave window seat cushion, set for company

*A window seat is the overflow chair nobody plans for. At every gathering I've ever hosted, it fills up first.*

> **The quick answer:** To seat guests on a window seat, fill it wall to wall with a deep boxed cushion, about 4 in (10 cm) thick, and add zippered back pillows so people can lean against the wall. Keep the cushion below the sill so the casement still opens. A ledge of 38 3/4 x 25 3/4 in got a 38 x 25 in cushion.

## What I see from the doorway

I'm writing from the doorway, the way a guest sees this seat first.

A white painted window seat sits under a casement that opens onto a leafy garden. The [window seat cushion](https://cushionguide.com/cushions/window-seat-cushions/) fills it wall to wall, in a dove gray and ivory basketweave with self piping. A taupe linen curtain hangs to one side. That's all, and it's plenty.

The cushion is deep, with a tall boxed side. That's what makes it a seat and not a pad: two people can talk here all evening without a hip bone complaining. The self piping gives a soft, chunky weave a tailored front edge, and the eye follows it to the window.

The colors are polite on purpose. Gray and ivory sit between the white paint and the taupe curtain, which repeats the darker yarn. The only real color is the garden, and the cushion lets it lead. More woven textures in [jacquard and damask](https://cushionguide.com/fabrics/jacquard-and-damask/).

Now look at the metal stay. The window still opens freely, because the cushion sits below the sill line. With a full [living room](https://cushionguide.com/cushions/living-room-cushions/) on a warm evening, that open window matters.

## Five pins, from the stay to the garden

Where I'd point a guest who asked why this seat feels so easy.

1. **Self piping**: Tonal piping runs along the front edge, giving a soft chunky weave a tailored outline.
2. **Casement stay**: The window still opens freely because the cushion sits below the sill line.
3. **Linen curtain**: Taupe linen repeats the darker yarn in the weave.
4. **Garden view**: Green foliage outside is the only color, and the gray cushion lets it lead.
5. **Deep side face**: A deep boxed side makes the seat comfortable enough for long reading sessions.

## Seating more than one

When company comes, a window seat does three jobs. It seats two or three, it holds a plate while someone talks, and it lets a tired guest lean back.

For the leaning, line the wall with back pillows. The workshop fills them with shredded foam it breaks down on its own machine, in a separate insert behind a zippered cover. The morning after, the covers wash at 86°F (30°C) on gentle.

For the sitting, 4 in (10 cm) is the standard [thickness](https://cushionguide.com/guides/window-seat-cushion-thickness/), and it's usually right, unless something has to clear it. How many people does your window seat need to hold on a good night?

## The window that had to swing over the cushion

One buyer wrote in with a hard limit. A window opened over the seat, so the cushions had to be ultra-thin: 3/4 in (2 cm) corduroy, at 68 x 21 1/4 in (172.5 x 54 cm) and 51 1/4 x 20 3/4 in (130 x 53 cm).

The first delivery went wrong in more ways than one. It came in plastic wrap without a box, one zipper was broken, and the uneven foam bulged to 1 1/2 to 2 in (4 to 5 cm) inside the cover. The replacement was made to the old sizes, not the updated 68 to 68 1/2 x 22 in (173 to 174 x 56 cm), and the foam alone measured 1 in (2.6 cm).

After a long back-and-forth, the workshop made a third set and confirmed every dimension with the buyer before it left. That last step is the one I'd paint on a porch post.

## Three questions from under the window

**A common question:** Can you make a cushion for an odd-shaped window ledge, or one with a cut corner?

**The workshop's answer:** Yes, custom shapes are made. Send a photo, or a drawing on paper of the shape with every size written on it, and the workshop quotes from that.

**A common question:** What's inside the back pillows, and does the cover come off for washing?

**The workshop's answer:** Shredded foam, broken into small pieces on the workshop's own machine, which gives a soft but supportive feel that holds its shape against a backrest. The filling is a separate insert and the cover zips, so it comes off and washes at 86°F (30°C) on a gentle cycle. Nothing is sewn shut.

**A common question:** My window ledge is 38 3/4 x 25 3/4 in. What size cushion should I order?

**The workshop's answer:** The workshop added a 38 x 25 in (97 x 64 cm) option to the listing, rounding down to whole inches so the cushion sits inside the ledge. The color goes in the order note, and the cushion is 4 in (10 cm) thick.

> If a window has to open over a window seat cushion, the foam must be cut under that height limit and the cover sized so it can't bulge above it.

## On the cutting table

|   |   |
|---|---|
| Cushion | Window seat cushion, box edge, deep side face |
| Fabric | Dove gray and ivory basketweave |
| Piping | Self piping on the front edge |
| Thickness | 4 in (10 cm) standard |
| Fit | Wall to wall, below the sill line |
| Back pillows | Shredded foam in a separate insert, zippered cover |
| Care | Covers off, 86°F (30°C) gentle |
| Best for | Living-room window seats that double as guest seating |

> **Tailor's margin:** Measure an old window seat at the back and at the front before ordering; the two widths are rarely the same, and the cushion has to clear both.

## Questions buyers ask next

### Should a window seat cushion sit below the sill?

Yes, whenever the window opens inward or has a stay that swings low. A cushion that stays under the sill line lets the casement open freely, which matters on a warm evening with guests. Measure seat to sill before choosing a thickness.

### Are window seat back pillows filled with solid foam?

No. They're filled with shredded foam in a separate insert, softer than solid foam but not very soft, so they keep a shape when someone leans back. The zippered outer cover comes off for washing.

### How thin can a window seat cushion go under a swinging window?

Cushions as thin as 3/4 in (2 cm) have been made where a window swings over the seat, but only without piping. At that thickness the foam has to be cut under the limit and every dimension confirmed before production.
