# How do I get a longer floor sofa, like a 3-seater?

*One floor sofa piece stops at about 79 in (200 cm). Past that, length is a matter of modules, and the arithmetic is friendlier than it looks.*

Also asked as: Can you do 94½ in (240 cm) in one piece?; Something longer to seat 3-4 people

> **The quick answer:** A 3 seater floor sofa longer than 79 in (200 cm) is built from modules, since one piece stops there. Add the 39 in (100 cm) ottoman with backrest for about 118 in (300 cm), a 16 or 24 in (40 or 60 cm) section for about 94 or 102 in (240 or 260 cm), or split a 98 in (250 cm) wall into two 49 in (125 cm) halves.

## Key facts

- A single floor sofa piece tops out at about 79 in (200 cm); 94 in (240 cm) in one piece is not possible.
- Adding the 39 in (100 cm) ottoman with backrest gives about 118 in (300 cm) as a 3-seater.
- The 118 in (300 cm) set includes an extra metal support.
- A separate 16 or 24 in (40 or 60 cm) section with its own seat and backrest extends the run.
- A 98 in (250 cm) wall can take two equal 49 in (125 cm) sections.
- Extension pieces can also be used on their own.
- Longer configurations are quoted and sold through a custom link.

## Four length questions, 94 to 118 inches

1. **“Can you make one piece 94½ in (240 cm)?”**: No. One piece stops near 79 in (200 cm). Past that, the extra length comes from a second module set beside it.
2. **“I need about 117 inches.”**: Add the ottoman with backrest to the 79 in sofa. The set reaches about 118 in (300 cm) and comes with an extra metal support.
3. **“What about 94½ or 102¼ in (240 or 260 cm)?”**: A separate section with its own seat and backrest goes beside the sofa: 16 in (40 cm) for about 94 in, 24 in (60 cm) for about 102 in.
4. **“My wall is 98½ in (250 cm).”**: Two equal 49 in (125 cm) sections fill 98 in (250 cm), so the join sits in the middle of the wall.

## Three routes past 79 inches

Partner, here's the arithmetic. One sofa piece stops at about 79 in (200 cm), and 94 in (240 cm) as a single piece isn't possible. Every longer [modular floor sofa](https://cushionguide.com/cushions/modular-floor-sofas/) is two or more modules set side by side.

The ottoman route is the true 3-seater: the 39 in (100 cm) ottoman with its own backrest brings the run to about 118 in (300 cm), and that set gets an extra [metal support](https://cushionguide.com/glossary/#metal-support-bars). The extension route adds a 16 or 24 in (40 or 60 cm) section with its own seat and backrest, and those pieces work apart too. Equal halves suit a fixed wall. There's also a sideways option: the sofa with an ottoman plus a straight backrest turned to make a 3-seater.

A 6 ft buyer who wants to lie down and a family who wants 3-4 seats end up at the same answer: modules, quoted and sold through a custom link. The [layouts pattern](https://cushionguide.com/guides/modular-floor-sofa-layouts/) and [support bar notes](https://cushionguide.com/guides/floor-sofa-support-bars-assembly/) cover the rest. Measure the wall twice; the fabric remembers. What does yours measure, corner to corner?

## Target length and the module recipe

| Target length | Recipe | Note |
|---|---|---|
| Up to 79 in (200 cm) | One sofa piece | Single-piece maximum |
| About 94 in (240 cm) | Sofa + 16 in (40 cm) section | Section has its own seat and backrest |
| 98 in (250 cm) wall | Two 49 in (125 cm) sections | Equal halves |
| About 102 in (260 cm) | Sofa + 24 in (60 cm) section | Pieces can be used separately |
| About 118 in (300 cm) | Sofa + 39 in (100 cm) ottoman with backrest | Includes an extra metal support |

> **Tailor's margin:** A floor sofa longer than 79 in (200 cm) is always two pieces; on a 98 in wall, two 49 in halves put the join dead center.

> One floor sofa piece stops at 79 in (200 cm); adding the 39 in ottoman with backrest turns it into a 118 in (300 cm) 3-seater.

## Buyer questions

**A common question:** Can the floor sofa be made longer, say 85 or 117 inches?

**The workshop's answer:** Not as one piece: a single sofa stops at 79 in (200 cm). Adding an ottoman with a backrest brings the total to 118 in (300 cm), and that set includes an extra metal support.

**A common question:** I need a longer 3-seater for a 98½ in (250 cm) wall. Can you do it?

**The workshop's answer:** Yes. Production can make two 49 in (125 cm) sections that together fill 98 in (250 cm). Another route is the sofa with an ottoman plus a straight backrest set sideways.

**A common question:** How would you build a floor sofa about 102¼ in (260 cm) long?

**The workshop's answer:** One sofa goes up to 79 in (200 cm), so a separate 24 in (60 cm) section with its own seat and backrest is added beside it. The pieces can also be used separately, and the set is quoted as one.

**A common question:** Can the teddy sofa be stretched to 94½ in (240 cm)?

**The workshop's answer:** The maximum is 79 in (200 cm). For 94 in (240 cm), a separate 16 in (40 cm) piece goes beside it; or add an ottoman with backrest and it becomes a 3-seater.

## Questions buyers ask next

### Can the extension section be used away from the sofa?

Yes. The 16 and 24 in (40 and 60 cm) sections have their own seat and backrest, so the pieces can be used separately and pushed back together when you want the full run.

### How do I order a length that isn't on the listing?

Send your target length and the layout you want. Longer configurations are quoted and sold through a custom link, so the price covers the exact modules, including the extra metal support on the 118 in set.

### Can one piece be made shorter than 79 inches instead?

Yes. Order the standard sofa and write your width in the note, for example 60, 65 or 70 in (152, 165 or 178 cm). Shorter pieces have been priced as the standard size; a custom width takes a little longer to make than a stock one, so ask for the current timing when you order.
