# What size should the back pillows be for a 79 in (200 cm) daybed like the Hemnes?

*A back pillow is sized from the wall it leans on, not from a catalog page. Here is how the workshop measures them, and why the height stops where it does.*

Also asked as: Dimensions of the back cushions on the daybed set?; Can I get 70 x 100 back pillows for my daybed?

> **The quick answer:** A 79 in (200 cm) daybed takes two back pillows of about 39 x 16 in (100 x 40 cm) each. Back pillows are sized by dividing the full span, so they sit flush end to end. About 16 in (40 cm) is the standard height; 27.5 in (70 cm) is too tall for a backrest. Other sizes are made to your measurements.

## Back pillow sizes on the cutting table

| Your seat | Back pillows | Height |
|---|---|---|
| 79 in (200 cm) daybed, such as the Hemnes | Two, each about 39 in (100 cm) long | About 16 in (40 cm), the standard |
| Any other span | The span divided evenly, cut to your numbers | About 16 in (40 cm) unless you give another |
| Dining nook, one order | Four, each about 19.5 x 31.5 in (50 x 80 cm) | Made to the buyer's measurements |
| A request for 27.5 in (70 cm) tall | Not advised | Too tall for a backrest |

## Divide the daybed span; don't guess the pillow size

Lay two back pillows end to end on a 79 in (200 cm) daybed and they should meet the ends with no gap and no squeeze. That is why the workshop sizes them from the full span. The span is split into equal pillows, and on a Hemnes each one comes out about 39 in (100 cm) long.

Height is the other half. About 16 in (40 cm) is the standard, and the set price is built on it. A seam is a promise, my friend, so settle both numbers before the fabric is cut. If you're working from a Hemnes, measure the mattress stack with the [Hemnes daybed cover pattern](https://cushionguide.com/guides/ikea-hemnes-daybed-cover-measuring/), then see how backs and bolsters dress it in [styling a daybed like a sofa](https://cushionguide.com/guides/daybed-back-cushions-sofa-look/). The full range lives in the [Hemnes daybed covers atlas](https://cushionguide.com/cushions/ikea-hemnes-daybed-covers/).

## The buyer who wanted them 27.5 inches tall

A buyer got in touch about a daybed cover set and asked whether the back pillows could stand 27.5 in (70 cm) tall. The workshop said no, plainly and kindly: the standard height is about 16 in (40 cm), the set price is figured on that, and 27½ in (70 cm) is too tall for a backrest.

For a 79 in (200 cm) Hemnes, two 39 in (100 cm) pillows span the full length, and [bolsters](https://cushionguide.com/cushions/bolster-pillows/) with their inserts come in the set. What does your daybed measure from end to end?

> **Tailor's margin:** Size daybed back pillows from the full span: a 79 in daybed takes two pillows about 39 in long and 16 in tall, set flush end to end.

> A back pillow 27.5 in tall is too tall for a daybed backrest; about 16 in is the standard height, and the set price is built on it.

## Buyer questions

**A common question:** What size are the back pillows in the daybed cover set? Could they be 27½ in (70 cm) tall?

**The workshop's answer:** The standard height is about 16 in (40 cm) and the set price is based on it, so a 79 in (200 cm) daybed gets two pillows of about 39 x 16 in (100 x 40 cm); 27½ in (70 cm) is too tall for a backrest. Two 39 in pillows span the full length of a Hemnes, and bolsters with inserts are included.

**A common question:** How big are the back cushions in the daybed set, and could I get four 19¾ x 31½ in (50 x 80 cm) backrests instead?

**The workshop's answer:** The set's back cushions are about 16 x 39 in (40 x 100 cm), but they are made to the measurements you give, so four 19.5 x 31.5 in (50 x 80 cm) backrests can be made too.

**A common question:** What length should backrest pillows be for my daybed or bench?

**The workshop's answer:** They're sized from the full span so they sit flush: give a total such as 78¾ in (200 cm) and the workshop splits it into two 39 x 16 in (100 x 40 cm) backrests. Matching bolsters in one set were 8 in (20 cm) across and 37.5 in (95 cm) long.

**A common question:** How do I size back pillows for an L-shaped or angled banquette?

**The workshop's answer:** Measure each wall's back line (the short wall is its seat length plus the long side's seat depth, minus the corner pillow), split it into 2-3 pillows about 16 in (40 cm) high, and leave about 1.5 in of allowance for plump pillows.

## Questions buyers ask next

### Do the back pillows have to be the same length?

The workshop divides the full span into equal pillows so they sit flush, which gives a 79 in (200 cm) daybed two pillows of about 39 in (100 cm). If you want a different split, write the sizes; pillows are made to your measurements.

### Are bolsters part of the daybed cover set?

Yes. The daybed set includes bolsters with their inserts, so they arrive ready to use at the ends. One set's bolsters measured 8 in (20 cm) across and 37.5 in (95 cm) long.

### Can I order the back pillows later and add them to a daybed I already have?

Yes. Back pillows are made to the measurements you provide, so give the full span of the daybed and the height you want, about 16 in (40 cm) being the standard, and they are cut to split that span evenly.
