# Is the backrest the same length as the seat cushion?

*Order a 59-inch seat and you get a 59-inch back. The rest is height, and height is where the choosing happens.*

Also asked as: Is the back cushion the same size as the bottom?; If I buy a 59 in seat, will the back be 59?

> **The quick answer:** Yes, a backrest cushion is made the same length as the seat cushion, so a 59 in (150 cm) seat comes with a 59 in back. The standard backrest is 16 in (40 cm) high and 4 in (10 cm) thick, tufted like the seat. Height can run from about 8 in to 16 in or taller.

| Seat you order | Backrest that comes with it |
|---|---|
| 59 in (150 cm) tufted seat | 59 in long, 16 in (40 cm) high, 4 in (10 cm) thick |
| 65 in (165 cm) seat | 65 in long, same tufting |

## Why the back follows the seat

A back that runs shorter than its seat looks like a coat with the sleeves cut off. So on the tufted floor cushion and bench sets, the backrest is made the same length as the seat, and on custom [floor cushions](https://cushionguide.com/cushions/floor-cushions/) it matches the seat's footprint. You choose the seat; the back follows.

What you do choose is height. Sixteen inches is the standard; lower works, down to about 8 in, and taller is no trouble. Read [back cushion height](https://cushionguide.com/guides/back-cushion-height-sizing/) and the [tufted floor couch set sizes](https://cushionguide.com/guides/tufted-floor-couch-set-sizes/) before you settle it.

The round [armrest bolsters](https://cushionguide.com/glossary/#armrest-bolster) are the one piece that doesn't match: they're made 4 in shorter than the seat depth, the same 4 in a standard backrest takes up. How tall is the wall behind your seat, my friend?

## What can change on a back without changing its length

- ✓ Height, from about 8 in (20 cm) to 16 in (40 cm) or taller
- ✓ A curved or rounded top edge
- ✓ A split into two pieces
- ✓ Custom dimensions, such as 36 in W x 8 in D x 12 in H
- ✓ The same tufting as the seat

> **Tailor's margin:** A backrest cushion is made as long as its seat: order a 59 in (150 cm) seat and the 16 in (40 cm) high back arrives 59 in long.

> Round armrests on a floor cushion set are made 4 in shorter than the seat depth, while the backrest runs the seat's full length.

## Buyer questions

**A common question:** If I order a custom floor cushion, what size is the back cushion?

**The workshop's answer:** The back matches the seat's footprint. A 16 x 29 x 6 in (41 x 74 x 15 cm) seat got a 16 x 29 in backrest at the standard 4 in thickness, and a 31 x 31 in seat gets a back made to its width.

**A common question:** How tall is the backrest, and can the shape change?

**The workshop's answer:** Standard is 16 in (40 cm) high and 4 in (10 cm) thick. The top can be curved or rounded, the back split in two, or the piece made to custom dimensions such as 36 in W x 8 in D x 12 in H.

**A common question:** If the seat is 59 in (150 cm), is the back 59 in too?

**The workshop's answer:** Yes, they're made the same length. The standard back is 16 in tall and can be made taller, and the round armrests are 4 in shorter than the seat depth.

## Questions buyers ask next

### What if the wall behind my seat is shorter than the seat run?

Order the back to the length you need. Backrests can be shorter than the seat and added as their own item, with the size, fabric code and the word 'backrest' in the personalization box.

### Does a tufted backrest have a zippered cover?

No. Tufting is sewn through the filling, so a tufted back has no zipper. If you want a back whose cover comes off, ask for a plain, non-tufted backrest instead.

### Are the seat and the backrest joined together?

No. Seat, backrest and bolsters are separate pieces, so the back can lie flat or be used on its own. Corner ties can be sewn on if you'd like the pieces tied together.
