A forest green window seat cushion, read corner first

Pull up a chair. Here is one corner of a forest green window seat cushion in raking light, with more porch in it than you would guess.

The quick answer

A window seat cushion should be cut to the seat itself, notched around any casing or trim rather than made shallower, and chosen in a fabric you have seen in side light. This forest green linen-look box cushion with ivory piping shows why: raking window light reveals the brushed weave, and the contrast cord marks a clean, tailored corner.

What the side light gives away

I learned to read fabric on my grandmother's wraparound porch, where the five o'clock light comes in low and sideways and tells the truth. This window seat cushion gets the same treatment indoors.

Up close, the green is not flat. Window light rakes across the top and picks out a brushed surface with a faint diagonal line and a little sheen. Under a ceiling light you would call it dark green and move on. In side light it is forest, with a texture you can almost feel.

Then the corner. An ivory cord turns it cleanly, no pucker, no drift, and that turn is what separates a tailored box cushion from a foam pad in a cover. The side wall runs as a straight, even band, so the front edge holds its line.

A gray linen curtain and a warm oak floor sit at the edges on purpose. They show how this linen-look fabric behaves beside a cool neutral and a warm wood.

What a window seat can borrow from the porch

Porch benches have posts, and nobody shaves a whole porch cushion shallower to clear one post; you cut around it. Window seats have the same trouble with casings and trim, and the same answer: a notch. The notched cushion guide shows how to draw one.

The porch lends one more habit. Out there, we judge fabric in the day's hardest light before we commit. Do the same inside: hold the sample beside the window, not in front of a screen.

What sits under your window right now, and does anything hang over its back edge?

A real project

The casing that hung over the back edge

A buyer in the US had a window seat 25 x 109.25 in (63.5 x 277.5 cm), with a casing 0.75 in (1.9 cm) deep sitting 1.5 in (3.8 cm) above it. The casing stopped 6 in short of the left end and 7 in short of the right.

The easy answer was a shallower cushion, with a gap along the wall. The workshop drew a notch instead, 0.75 in deep and 96.25 in wide along the back edge, so the cushion steps around the casing and still meets the wall at both ends. It cost the same as a plain rectangle.

After several linen close-ups, the first picks too gray, the buyer chose a warm linen, 4 in thick.

Sizes
25 x 109.25 in seat; notch 0.75 x 96.25 in; 4 in thick
Fabric
Warm linen

The lesson: Notch the back edge around a casing instead of shrinking the whole cushion.

When a window casing hangs over the back of a seat, notch the cushion's back edge around it instead of making the whole cushion shallower.

Buyer questions: length, firmness and cost

  1. A common question

    My window seat is longer than any size in the drop-down menu. How do I order it?

    The workshop's answer

    Pick the closest size, say 20 x 92 in for a 20 x 94 in cushion, and write your exact dimensions in the personalization box; that is what gets made. The drop-down mainly sets the price. For very long sizes, the workshop adds a custom option just for you.

  2. A common question

    How firm is the foam, and should I go with 3 in or 4 in?

    The workshop's answer

    Every cushion uses medium-firm high-resilience foam, about 2.0 lb/ft³ (32 kg/m³), that keeps its shape for years without sagging or flattening. The 3 in (7.6 cm) option is the best seller.

  3. A common question

    Roughly what does a custom window seat cushion cost?

    The workshop's answer

    Price climbs with size: past quotes run from seats like 30 x 12.5 in to long runs like 24 x 102 in. Send your exact size for a quote.

Questions buyers ask next

Is a notch better than a shallower window seat cushion?

Usually, when trim hangs over the seat. A shallower cushion leaves a gap along the whole wall; a notch removes depth only under the casing and leaves both ends full depth.

How should I judge a dark green fabric before ordering?

Look at a close-up or sample in side light, beside your room's materials. Screens flatten texture and shift color; the buyer above rejected the first linen picks as too gray.

Does contrast piping suit a dark window seat cushion?

It looks very tailored. Ivory cord on forest green outlines every corner, so it rewards a straight line and shows any wander. For one quiet block of color, choose self piping.
