The Studio
Eight free tools, each built around a question buyers ask again and again — angles that won't add up, depths nobody wrote down, cushions that turned out too tall. Three builders show a cushion before it is cut; five calculators do the arithmetic and draw it to scale.

The quick answer
The Studio is the atelier's free set of cushion tools: 3D builders for bench cushions, chair pads and pillow covers, and calculators for bay windows, trapezoid shapes, fabric yardage, foam firmness and seat height. Each answers a question buyers ask again and again, runs in the browser, works in inches or centimeters, and keeps your numbers in a link you can share.
See it before it is cut
Turn the cushion in your hand: size, thickness, fabric, piping, ties.
- 3D builder3D bench cushion builderBenches, window seats and bays: shape, size, thickness, fabric and piping on a live 3D cushion, with a cut list in inches and cm.A common question: Can you show me the main fabric and the piping color together before I order?
- 3D builder3D chair cushion builderSeat pads that tie on and stay put: square or tapered, with ties, piping and thickness, in 3D from every angle.A common question: Can you make a seat cushion that is wider at the front than the back, for my chair?
- 3D builderPillow cover studioThrow, lumbar and bolster covers: size, fabric, piped or plain edge and closure, previewed in 3D before a stitch.A common question: Should I get piping on my pillows or not?

- Calculator · MaggieBay window calculator3-, 5- or 7-sided bays: walls and angles (or just the depth) in; a to-scale plan and every cushion piece out.A common question: Our bay window seat has weird angles. How do I give you the measurements?
- Calculator · NateTrapezoid cushion calculatorAny three of front, back, depth, side or angle give the rest — plus a sketch check and a 1:1 printable template.A common question: What happens if the slanted sides on my sketch don't add up?
- Calculator · ÉlodieFabric yardage calculatorA list of cushions, a roll width, stripes and repeats, piping: every panel laid on the fabric, yards and meters to buy.A common question: Could I use my own fabric? If so, how much would be needed?
- Calculator · CallumFoam firmness finderFive questions — where, who, how you sit, how thick, how often — give a foam type, density, firmness and thickness.A common question: What foam do you use, how firm is it, and will adults sink through?
- Calculator · HanaSeat height calculatorBench, table and your own height in; the cushion thickness that keeps feet on the floor and knees under the table.A common question: Will the cushion be too tall? We have a table next to the bench.

The questions behind the tools
- A common question
Can you check my measurements and decide the final size for me? Is your drawing exact?
The workshop's answerThe cushion is made strictly to the dimensions you give. The workshop turns your numbers into a drawing so you can check the shape, but the final numbers are yours to confirm — sketch them on paper and send a photo.
- A common question
How do I measure a window seat for a custom cushion?
The workshop's answerFront edge wall to wall, back edge along the window (often shorter), depth front to back — on both sides if it varies — and each angled side separately. Use a rigid tape on the seat itself and sketch it from above with every number on its edge.
- A common question
What thickness options do you have, and does thickness change the price?
The workshop's answer2, 3, 4 and 5 in are standard, 2.5 in has been made on request and 6 in is possible; for a given size they cost the same. For a bench beside a dining table, 2 or 3 in are the popular choices.
- A common question
Can you show me two fabrics side by side, so I can see the main fabric with the piping?
The workshop's answerYes, the two chosen swatches can be photographed side by side — but not every finished combination, because there are hundreds of colors, and photos shift with the light. Samples are the final word on color.
Questions people ask
Are the Studio tools free?
Yes. Every builder and calculator is free, needs no account and runs in your browser.
Can I save or share my numbers?
Yes. Every calculator keeps your inputs in the page link. Press Copy link to these numbers and the link opens with exactly the same drawing — for yourself later, for a partner, or for the workshop making the cushion.
Do the calculators work in inches?
Yes. Every tool opens in inches; switch to centimeters at the top of any calculator. Results always show both, with inches to the nearest eighth.
How accurate are the drawings?
The geometry is exact; the drawings are to scale on graph paper, and the trapezoid template prints at full size. The answer is only as good as the tape measure, so measure on the seat itself and check the depth the tool gives against your own.
Which tool should I start with?
Angled or odd-shaped seats: the bay window or trapezoid calculator. Plain rectangles: go straight to the 3D bench builder, then check thickness with the seat height calculator and the foam firmness finder.
