# How big is the floor sofa ottoman, and does it fold open?

*One square. Two layers. It opens into a longer rectangle.*

Also asked as: Does the ottoman unfold into a rectangle?; Is the yellow ottoman corduroy and foldable?

> **The quick answer:** The floor sofa ottoman is 39 x 39 in (about 100 x 100 cm), made as one connected, foldable piece whose two stacked layers open flat into a longer rectangle, like two pillows side by side. It uses the same foam as the sofa, and on the corduroy sofa it is corduroy too. The layers can be made separate on request.

## Three pieces, and which of them fold

| Piece | Size | Folds? |
|---|---|---|
| Ottoman | 39 x 39 in (about 100 x 100 cm) | Yes. Two connected layers open flat into a longer rectangle. |
| Seat mattress | The size you order | Not as standard. Can be made as 2 ottoman-style pieces that fold. |
| Straight backrest | About 39 in (100 cm) long | No. Sold on its own if you want one more. |

## Same foam, same cloth

The ottoman feels like the sofa because it is made of the sofa's foam. On the corduroy sofa it is [corduroy](https://cushionguide.com/fabrics/corduroy/) too.

Its two layers are joined. Folded, it is a square footrest. Opened, it lies flat as a longer rectangle, like two pillows side by side. If you would rather have two loose cushions, ask for the layers as separate pieces.

There is no narrower ottoman as standard. Narrower ones have been made as custom orders. The [ottoman cushions](https://cushionguide.com/cushions/ottoman-cushions/) and [modular floor sofas](https://cushionguide.com/cushions/modular-floor-sofas/) pages show both kinds.

## When the seat should fold too

The main seat mattresses do not fold as standard. They can be made as 2 ottoman-style pieces, so the seat folds the same way. The [floor sofa bed size Pattern](https://cushionguide.com/guides/floor-sofa-bed-size-firmness/) and the [modular layouts Pattern](https://cushionguide.com/guides/modular-floor-sofa-layouts/) help you decide if the seat needs to fold.

Will yours be a footrest most days, or something you lie on?

A square for your feet.
A longer rectangle when you open it.
The same foam either way.

## Buyer questions

**A common question:** How big is the ottoman, does it open into a bed, and does it feel like the sofa?

**The workshop's answer:** It is 39 x 39 in (about 100 x 100 cm), with no narrower version as standard. It's one connected piece that folds open into a longer rectangle, like two pillows side by side, in the same foam as the main couch. The main couch cushions don't fold as standard, but they can be made foldable on request.

**A common question:** Is the ottoman corduroy, and does it fold?

**The workshop's answer:** Yes to both. Its two stacked layers are connected, so it opens flat or folds back, and they can be made as separate pieces on request.

**A common question:** How long is the straight backrest, and does the ottoman open?

**The workshop's answer:** The straight backrest is about 39 in (100 cm) long and can be bought on its own. The modular sofa's ottoman flips open.

**A common question:** The photos show two ottoman styles. Which one will I get?

**The workshop's answer:** The one in the first photo is sent as standard. Send a picture of the other one if that is the style you want.

## Questions buyers ask next

### Does the floor sofa set include a backrest and armrests?

Yes. The floor sofa set is one seat cushion, a matching-length backrest about 16 in (40 cm) tall and two round armrest bolsters, all filled. You only choose the size and the color.

### What holds the backrests up on a modular floor sofa?

Four free-standing metal frames, two at the sides and two at the back, keep the backrests from sliding or tipping when you lean. They are not attached to the cushions and stay put once you sit.

### Do the decorative pillows in the sofa photos come with the ottoman set?

Not always; it depends on the listing. The linen floor sofa includes every pictured piece, while decorative pillows on the kids corner cushion are sold separately. Matching pillows can be made in the same fabric.
