# Will a made-to-measure daybed cover fit a Brimnes, a twin or a thick mattress?

*The listing says Hemnes. The measurements on the order are yours, and they are what the cover is cut to.*

Also asked as: Does this fit the IKEA Hemnes daybed?; Is it compatible with the Brimnes daybed?

> **The quick answer:** The IKEA Hemnes daybed cover is made to measure, so it fits a Hemnes, a Brimnes, a standard twin or any custom mattress. Write the mattress length, width and thickness in the personalization box, for example 39 x 75 x 5 in (99 x 190 x 13 cm). Thicker mattresses of 8 in (20 cm) or 9.5 in (24 cm) are fine.

## Key facts

- The daybed cover set is designed around the IKEA Hemnes.
- Each cover is cut to the mattress you measure, so a Brimnes or a twin works too.
- Length, width and thickness go in the personalization box.
- If the thickness is missing, the workshop asks for all three after purchase.
- Mattresses 8 in (20 cm) or 9.5 in (24 cm) thick are fine.
- Choose the full set or the cover only; a spare mattress cover comes on a separate link.
- Matching curtains are not offered.

## Before you place the daybed order

- ✓ Measure the mattress, not the frame: length, width, thickness.
- ✓ Two mattresses stacked? Give their combined thickness.
- ✓ Write all three in personalization, e.g. 31.5 x 79 x 9.5 in (80 x 201 x 24 cm).
- ✓ Choose the full set or the cover only.
- ✓ Want a spare mattress cover? Ask for the separate link.
- ✓ Curtains to match are not part of the range.

## Your daybed, and what to write

| Daybed or mattress | What to write | from past orders |
|---|---|---|
| IKEA Hemnes | Mattress length x width x thickness | The set is designed around it |
| IKEA Brimnes | The exact mattress size | Mattress cover plus 2 backrests, no armrests |
| Standard twin | e.g. 39 x 75 x 5 in (99 x 190 x 13 cm) | Made to those numbers |
| Two stacked mattresses | Combined thickness | Two 4 3/4 in (12 cm) layers became one 9 1/2 in (24 cm) cover |

## A name gets you to the listing

Daybed mattresses vary, even between two daybeds that share a name. So the cover is not cut to a catalog size. It is cut to what you measure.

That is why a Brimnes, a twin or a stacked pair all work. The [Hemnes cover measuring Pattern](https://cushionguide.com/guides/ikea-hemnes-daybed-cover-measuring/) shows where the tape goes, and [Hemnes daybed covers](https://cushionguide.com/cushions/ikea-hemnes-daybed-covers/) shows finished sets. The [corduroy](https://cushionguide.com/fabrics/corduroy/) option is thick and high quality. How thick is your mattress?

The name finds the listing.
The numbers find the fit.
The rest is fabric.

> **Tailor's margin:** An IKEA Hemnes daybed cover also fits a Brimnes or a standard twin when the order gives mattress length, width and thickness.

> A made-to-measure daybed cover follows the mattress, not the brand: an 8 in or 9.5 in thick mattress is fine once all three dimensions are written down.

## Buyer questions

**A common question:** Will the Hemnes cover set fit my IKEA Brimnes, with backrests but no armrests?

**The workshop's answer:** Yes, it fits: order and write the exact size of your mattress. For the mattress cover plus backrests without armrests, add the mattress cover and 2 backrest pillows to the cart one by one. They ship together.

**A common question:** Will it fit a standard twin mattress, or a custom size?

**The workshop's answer:** Yes. Everything is made to your exact dimensions, written in personalization. For two stacked 4 3/4 in (12 cm) mattresses, the cover was made at the measured 78 3/4 x 35 1/2 x 9 1/2 in (200 x 90 x 24 cm).

**A common question:** My mattress is 8 or 9.5 inches thick. Will the cover fit?

**The workshop's answer:** Yes, it is made to measure. Put the thickness in the order notes; after purchase the workshop confirms length, width and thickness, for example a 31.5 x 79 x 9.5 in cover.

**A common question:** Can the set be made for a 7¾ in (20 cm) mattress, with a spare mattress cover?

**The workshop's answer:** Yes, in any size, including a mattress about 8 in (20 cm) thick. A spare mattress cover comes on a separate link. The fabric is a thick, high-quality corduroy. Matching curtains aren't offered.

## Questions buyers ask next

### Do the backrests and bolsters need their own measurements?

No. Backrests and bolsters are sized from your mattress cover measurements. Standard backrests are about 19 3/4 in (50 cm) high, and other heights are possible if you ask when you order.

### Can I order the daybed slipcover without backrests or foam?

Yes. Choose the Cover Only option on the daybed cover set and write your exact mattress dimensions and fabric code in personalization. You receive the slipcover alone, with no backrests, armrests or foam.

### Which fabrics does the daybed set come in?

Corduroy, velvet or linen, with cover and piping in any color on the chart. Pieces can even use different fabrics. The price changes with the option you pick: cover, backrests, armrests or the full set.
