The Cutting Table · a question, worked through

Can you make a cushion for a bay window with 5 windows, all at different angles?

Five windows instead of three is not a special case, partner; it is the same job with two more lines on the drawing. Here is the thread as buyers actually ran it.

The quick answer

Yes: a bay window seat cushion can have any number of angles, including 5-window, pentagon and hexagon bays. Send a rough sketch with every side or segment measured, the angles if you know them, and the depth at each breaking point. The workshop turns it into a template for you to check, then you order by the nearest length and width range.

Key facts

  • Bay window cushions with any number of angles are made regularly, including pentagon and hexagon shapes.
  • Measure every side or segment, plus the angles if you know them.
  • Give the depth at each breaking point, not only the deepest one.
  • Your sketch comes back as a template for you to check before anything is cut.
  • Order by the length and width ranges that cover the seat, then write the full shape in personalization.
  • A real 5-window bay ran 115 7/8 in (294 cm) long and 16 in (41 cm) deep at its deepest, made 4 in (10 cm) thick.

“It has 5 windows, not 3. Can you still make it?”

Yes. Multi-angle bays are made regularly: 5-window bays, pentagon and hexagon seats, windows each at a slightly different angle. The count of angles doesn't matter. The count of measurements does.

Angles are just lengths in disguise. Give every side and every depth and the angles fall out of the drawing. The bay window calculator is a good place to test your sketch first.

“What exactly do I measure?”

  1. Sketch the seat from above

    Rough is fine. Number the segments along the back wall, left to right.

  2. Measure every side

    Front edge, each back segment and both end sides.

  3. Add a depth at each breaking point

    Wherever the wall changes direction, measure straight out to the front edge.

  4. Check the template

    Your sketch comes back as a template to check before cutting.

“So is it a trapezoid with extra edges?”

For ordering, yes. Choose the length and width ranges that cover the seat, for example 78 in (198 cm) and 22 in (56 cm); they only set the size bracket. Then write the full shape in the personalization box: front, back, angled sides, end sides and depth. The 5-sided bay window cushion pattern walks through the layout, and the bay window cushions hub shows finished seats.

A real project

A 5-window bay, 115 7/8 in end to end

A buyer sent a bay of five windows, each at its own angle, with every segment measured and a depth at each breaking point. At its deepest the seat was 16 in (41 cm); end to end, 115 7/8 in (294 cm). It was cut at the standard 4 in (10 cm) thickness, in linen with contrasting piping. Nothing exotic. Just a longer list of honest measurements.

Measured
115 7/8 in long · 16 in at the deepest point · 4 in thick
What it taught
Five windows need no special process, only a depth at every corner.

Buyer questions

  1. A common question

    Can you make a bay window cushion with several angles?

    The workshop's answer

    Yes, multi-angle bay window cushions are made regularly. Send a rough diagram with the measurements, and the workshop checks and confirms it.

  2. A common question

    My bay is an odd shape: 5 windows at different angles. Is that possible?

    The workshop's answer

    Yes, many angled bay cushions have been made. Send a rough sketch with every side's length and the angles for a quote and advice.

  3. A common question

    Mine has two extra edges, more pentagon or hexagon than trapezoid. Can you make that?

    The workshop's answer

    Yes. Send the exact length of every side or a simple sketch, and it comes back as a template for you to check. Then pick the ranges that fit and write the full shape in personalization.

Questions buyers ask next

What is a breaking point on a bay window seat?

Each corner where the back wall changes direction, usually between two windows. The seat depth can change there, so a depth is needed at every one.

Are lengths enough, or do I need the angles too?

Lengths are enough. Every side plus the depth at each breaking point lets the shape be drawn and checked; angles are a useful extra.

How thick should a 5-window bay cushion be?

The 5-window example was made at the standard 4 in (10 cm). Thickness is chosen apart from the shape; the window seat thickness pattern helps you pick.
