# Can you make a large U-shaped floor sofa?

*A U is two corners and the distance between them. Draw that first, and the order writes itself.*

Also asked as: A 12-seater with two corner seats; U shape with an ottoman on the other side

> **The quick answer:** Yes, a large U-shaped floor sofa can be made to order from three modules, with module A, 35.5 x 35.5 in (90 x 90 cm), at every corner. Sketch the room and label each seat by module: B is 47 x 35.5 in (120 x 90 cm), and C is 23.5 x 35.5 in (60 x 90 cm). A custom L plus an extra ottoman also makes a U.

## Key facts

- Module A is 35.5 x 35.5 in (90 x 90 cm) and is required at every corner.
- Module B is 47 x 35.5 in (120 x 90 cm).
- Module C is 23.5 x 35.5 in (60 x 90 cm).
- A custom L-shaped sectional plus an extra ottoman forms a U.
- Discontinued models can be made to order at a higher price.
- One custom build was quoted at about 1 week to 10 days of making.

## Draw the room before you order the sofa

Take a sheet of paper. Draw the walls. Mark where the U should sit.

Then label every seat. On the boucle modular model there are three modules. A is the square, 35.5 x 35.5 in (90 x 90 cm), and every corner must be an A. B is 47 x 35.5 in (120 x 90 cm). C is 23.5 x 35.5 in (60 x 90 cm). A U has two corners, so it starts with two A modules; B and C fill the runs between them.

One buyer in the US had a 180 x 180 in room. The layout came out as two corners with B modules between them, roughly double the standard set. That is a lot of sofa. Leave a hand's width of floor. [Floor sofa height and space](https://cushionguide.com/guides/floor-sofa-buying-guide-height-space/) helps with the walkways, and [modular floor sofa layouts](https://cushionguide.com/guides/modular-floor-sofa-layouts/) shows more shapes.

Two corners.
The runs between them.
Everything else is labels.

## The 3 floor sofa modules, side by side

| Module | Size | Where it goes |
|---|---|---|
| A | 35.5 x 35.5 in (90 x 90 cm) | Every corner |
| B | 47 x 35.5 in (120 x 90 cm) | Along the runs between corners |
| C | 23.5 x 35.5 in (60 x 90 cm) | Shorter gaps in a run |

## The other way to a U: an L and an ottoman

On the teddy range, the workshop builds a custom-size L-shaped sectional and adds an extra ottoman on the other side. The ottoman closes the shape into a U, and that side stays a separate piece.

A model that has been discontinued can still be made to order, at a higher price. One custom build was quoted at about 1 week to 10 days of making. The [modular floor sofas](https://cushionguide.com/cushions/modular-floor-sofas/) hub shows the current shapes.

## Sketching a U the workshop can read

1. **Measure the walls**: Note each run the sofa will follow, in inches.
2. **Draw the U**: Sketch it on paper, corners and open side included.
3. **Place the corners**: Put an A module at each of the two corners.
4. **Fill the runs**: Label every other seat B or C so the lengths add up along each run.
5. **Send it with the fabric**: Add the model and color, and the workshop quotes the layout.

> **Tailor's margin:** A U-shaped floor sofa has two corners, and each corner must be an A module: 35.5 x 35.5 in (90 x 90 cm).

> A U-shaped floor sofa for a 180 x 180 in room came to roughly double the standard set: two corner modules with B modules between them.

## Buyer questions

**A common question:** Can you make a big U-shaped floor sofa, and how do I describe the layout?

**The workshop's answer:** Yes. Draw the layout on paper and label each seat by module: A is 35.5 x 35.5 in (90 x 90 cm) and every corner must be an A, B is 47 x 35.5 in (120 x 90 cm), and C is 23.5 x 35.5 in (60 x 90 cm). For a 180 x 180 in room, a U with two corners and B modules between them came to about double the standard set.

**A common question:** Could I get a custom-size L-shaped floor sofa plus an ottoman to make a U?

**The workshop's answer:** Yes. The workshop can build a custom-size L-shaped sectional and add an extra ottoman on the other side to create a U-shaped layout.

**A common question:** What's the difference between an open and a closed corner?

**The workshop's answer:** A closed corner ends in an L-shaped backrest that wraps the end; an open corner ends in a straight backrest, leaving it open like a chaise. Ask for an open end in the order note or add a straight backrest.

**A common question:** What size is the floor sofa in the photos, and what fits three people?

**The workshop's answer:** The photos mostly show 28 x 56 in (70 x 140 cm); some show 28 x 60 or 28 x 64 in. For three people, choose 28 x 64 in. Any length can be made to order.

## Questions buyers ask next

### Can I still order a floor sofa model that has been discontinued?

Often, yes: a discontinued model has been made to order at a higher price, and the making time comes with the quote. Name the model in your message so the right pattern is used.

### How many support bars come with a bigger layout?

It depends on the set: a single teddy sofa includes 4 bars, a 3-seater 5, the L-shape with ottoman 6, and a full corner set 8 large plus 8 small pieces. Missing bars: send a photo, and get the workshop's answer in writing.

### Which fabrics do the U-shaped layouts come in?

The A, B and C modules belong to the boucle modular model, while the L-plus-ottoman route uses the teddy range. Name the model and color on your sketch so the quote matches the right system.
