A Reading by RosaWindow Seat Cushions
A cream diamond-lattice window seat cushion, and the project behind the pattern
A plaster nook, a quiet pattern and a real order from my notebook: the question, the choices and the snag with the window handles.
SaveThe quick answer
A window seat cushion can be shaped around window handles or other obstructions that reach into the seat; mark each one on your drawing. In one real 13 × 92 in (33 × 234 cm) linen project, the custom shape cost about 10% more than a plain rectangle, with 3 to 5 business days of making and 3 to 5 days of shipping.
What the plaster nook shows
There's a kind of window I have always loved: a deep plaster reveal, a sash that really opens, sheer linen hanging to the floor. Somebody built a seat into this one and did it right.
The window seat cushion fills the reveal wall to wall, the way a built-in should. It rests on an oak cap, and that cap does two jobs. It frames the cushion from below like a picture mat, and it keeps the limewash underneath clean when folks climb up in their shoes. Kids and dogs are the real quality control, and bare plaster doesn't survive them without a little wood in between.
The fabric is cream woven with a cocoa diamond lattice, drawn in short broken strokes like running stitches. In a room where every surface is warm off-white, a plain cream cushion would melt into the wall. The lattice keeps the seat visible without bringing a new color into the house, because brown on cream is just the wall's color with one darker friend. It belongs to the jacquard family, where the pattern is woven in. The piping is cut from the cream ground, so the edge stays quiet and the lattice does the talking.
Props? Barely any, and that's the lesson. An olive branch in a cream jug on the floor, gray-green leaves to cool the brown. A cream wool rug. Sheers that soften the light. You could sit here with a cup of coffee and nothing else.
Is there a window at your house that's asking for this, neighbor?

Five things in the nook, jotted down in order.

- Diamond lattice weave
A cocoa lattice on cream adds pattern without darkening a pale plaster nook.
- Piped front edge
Piping in the ground color keeps attention on the pattern.
- Oak ledge
The cushion rests on an oak cap, which keeps the plaster below clean.
- Olive branch jug
Gray-green olive leaves cool down the warm brown of the lattice.
- Sash window
The seat fills the reveal wall to wall, the defining trait of a built-in.

The window handles that got in the way
A buyer wrote to the workshop wanting a linen window seat cushion, 13 × 92 in (33 × 234 cm), in beige oat, and couldn't decide between maroon and sky-blue piping. Both were good choices, and both stayed on the table.
Then came the snag. The window handles reached down into the seating area, so a plain rectangle would have bumped them all day. The workshop offered to cut a custom shape around the handles for about 10% more. Making took 3 to 5 business days, and shipping another 3 to 5.
One question, one color decision, one obstacle, one honest fix.
- Sizes
- 13 × 92 in (33 × 234 cm)
- Fabric
- Beige oat linen; maroon or sky-blue piping
The lesson: Mark every obstruction on your drawing; shaping around it costs a little more than a plain rectangle, and far less than a cushion that bumps the handles.
Marking an obstruction on your drawing
Measure the plain seat first
Length and depth, wall to wall, without subtracting anything. The workshop adds its own seam and fit allowances.
Find every obstruction
Window handles, a latch, a casing that steps in. Anything that reaches into the seat goes on the drawing.
Measure where it sits
From the nearest end of the seat to each side of the obstruction, and how far it reaches in from the wall.
Draw it and photograph it
Sketch the seat from above, write every number on it, and send a photo of the drawing with a photo of the window.
Order the custom shape
Shaped seats go through the custom-shape listing. Notches at the edges work; holes in the middle of a cushion are not offered. The notched cushion Pattern shows more.
Buyer questions: price, exact size and washing
- A common question
About how much does a custom cushion for a bench or window seat cost?
The workshop's answerThe listing works it out when you enter width and length, so you see it before checkout. The same size can differ between corduroy and linen, and piping costs nothing extra. A very low price on the listing belongs to the smallest sizes; it isn't a sudden sale.
- A common question
My exact size isn't listed. Do I choose the nearest standard size or give my own measurements?
The workshop's answerBoth. Pick the range your size falls into, only to set the price, then write your exact measurements, thickness and fabric code in the Add Personalization box. The cushion is made to what you write, fractions included, such as 57⅝ × 15⅜ in.
- A common question
Do the covers come off, and can they go in the washing machine?
The workshop's answerYes. The covers zip off and machine wash at 86°F (30°C) or lower. That holds for the linen-look, corduroy, velvet and trapezoid cushions, and the foam insert is included in the price.

Tell the workshop who sits there: grandkids, the dog, a cup of coffee at six. The right fabric and foam follow from the people. — Rosa
Leave your details and the workshop will call you to confirm measurements, fabric, foam and piping. No prices, dates or payment on this page: it is a request, not an order.
If window handles reach into a window seat, mark them on the drawing: a 13 × 92 in cushion shaped around them cost about 10% more than a plain rectangle.

Questions buyers ask next
Can a cushion have a hole cut in the middle for a vent?
No. Cut-outs inside the panel, such as for a floor vent, are not offered. Shaping at the edges is: notches and cut-outs around handles, posts or casings, drawn on your plan.
Maroon or sky blue: how do I choose a contrast piping?
Piping is included either way, and contrast costs the same as matching. Ask for side-by-side daylight photos of the body fabric with each piping code; the workshop sends them free on request.
Can the zipper face the wall?
Yes. The zipper sits on the back edge, facing the wall, or on the underside, and you choose which. On long seat covers it often wraps two corners so the foam slides out.
