# How can I make a daybed look like a sofa with back cushions?

*A daybed wants to be two things at once. Give it a fitted coat and a straight back, and it will sit like a sofa all day long.*

Also asked as: Make daybeds look like sofas for reading; Two back pillows, extra tall

> **The quick answer:** To make a daybed look like a sofa, order a fitted mattress cover with back cushions. Send the overall mattress length, width and depth, such as 38 x 80 x 10 in (97 x 203 x 25 cm) for a twin XL. Back pillows can be made extra tall, like 26 in (66 cm), and foam-filled so they stay structured when you sit upright.

## Two real daybeds, two recipes

## What makes a daybed sit like a sofa

A daybed looks like a bed because it is one: a long mattress, open on three sides, nothing to lean on. Give it a fitted mattress cover and a proper back, and folks walking past will call it a sofa.

The back is where most people go wrong, my friend. Ask for the backrest and armrest to be foam-filled, and they stay supportive and structured, the way a sofa back ought to. Buy the cushion once, cry once. The [daybed back cushions](https://cushionguide.com/guides/daybed-back-cushions-sofa-look/) Pattern and the [daybed sofa sets](https://cushionguide.com/concepts/daybed-sofa-cushion-sets/) Concept Sketch show more ways to dress one.

## Measuring for the set

1. **Measure the mattress, not the frame**: Overall length, width and depth in inches, as in 38 x 80 x 10 in for a twin XL. The [daybed mattress cover](https://cushionguide.com/guides/daybed-mattress-cover-measurements/) Pattern covers the tape work.
2. **Decide the back**: Two tall back pillows, such as 26 in (66 cm), or one long back cushion. Ask for foam fill if you mean to sit upright.
3. **Decide the arms**: One armrest bolster, two, or none. Mixing and matching is allowed.
4. **Ask to see the models**: The shop can send photos of its backrest models before you decide.

## Two twin XL beds under the windows

A buyer in the US had twin XL daybeds set against windows and wanted them to read as sofas, good for an afternoon with a book. The mattresses measured 38 x 80 x 10 in (97 x 203 x 25 cm).

The answer was a mattress cover with backrests, and back pillows made extra tall, 26 in (66 cm), to span the mattress against the window. Nothing fancy. Just the right numbers, sewn the right way.

> **Tailor's margin:** For sitting upright on a daybed, ask for the backrest and armrest foam-filled so they stay structured instead of loose.

## Buyer questions

**A common question:** Can you make a daybed set with one long supportive back cushion, one bolster and a fitted cover?

**The workshop's answer:** Yes. The backrest and armrest can be foam-filled so they're supportive and structured, and photos of the backrest models were shared before ordering. The mattress cover is made to size, for example a twin at 39 x 75 x 11.5 in (99 x 191 x 29 cm), in green corduroy.

**A common question:** Can I buy just the back pillows and bolsters for my daybed?

**The workshop's answer:** Yes. Backrests and armrest bolsters are sold without the mattress cover and quoted on request. Two 18 x 36 in (46 x 91 cm) backrests plus two armrests turn a twin bed into a daybed.

**A common question:** Does the cushion price include the back cushion, or just the seat?

**The workshop's answer:** Just the seat. Standard bench and outdoor listings price one seat cushion only. Add each back cushion as its own item in its own size and note 'backrest' plus your fabric code so they're made as a matching set.

## Questions buyers ask next

### How tall should daybed back cushions be?

Tall enough to give a real back to lean on. Back pillows have been made extra tall, such as 26 in (66 cm), for twin XL daybeds under windows, while 18 x 36 in (46 x 91 cm) backrests suit a twin.

### Do I measure the daybed frame or the mattress?

The mattress. Send its overall length, width and depth; the fitted cover is sewn to those numbers, like 38 x 80 x 10 in (97 x 203 x 25 cm) for a twin XL.

### Can I have a bolster on only one end?

Yes. Daybed sets mix and match: one long back cushion with a single armrest bolster has been made, and the bolster can be foam-filled so it holds its shape.

### How do I make a deep daybed seat feel like a sofa?

Fill the depth, not just the height. A twin mattress is about 39 in deep while a sofa seat is about 22 in, so the back cushions have to bring the wall forward by roughly 17 in. Thick foam backrests do that firmly; three or four large square pillows of 24 to 26 in do it softly but need regular plumping.
