The Cutting Table · a question, worked through

Should I add a little to my mattress measurements so the daybed cover fits tight?

No. The extra is already in the pattern. Add your own and it is there twice.

The quick answer

For a fitted mattress cover, send the mattress's exact measurements, because the workshop adds the seam and fit allowance itself when it cuts. Padding the numbers puts the allowance in twice, so the cover sits loose, and that is where crinkles come from. Measure your own mattress too, since Hemnes mattresses vary by country.

Key facts

  • Send the mattress's exact length, width and thickness.
  • The workshop builds seam and fit allowance into the cutting.
  • Padded measurements make the cover loose and crinkled.
  • For two stacked mattresses, give the combined height.
  • Hemnes mattress sizes vary by country, so measure your own.

Fabric
The cover cloth: weave, color and care code.
Foam
The core: its density and thickness set the feel.
Piping
The corded seam edge: matching, contrast or none.
Only for this request: no marketing calls or texts. Outside the US, add the country code.
In inches: length × depth × thickness, plus any angles or cut corners.

“Should I add an inch to be safe?”

No. Write what the tape says, for example 74 x 37 x 7 in (188 x 94 x 18 cm). The cover is cut slightly larger than those numbers so the mattress slides in. That fit allowance is the workshop's job.

Add your own inch and the allowance is there twice. The cover sits a little loose, and loose fabric crinkles.

“We have two mattresses stacked.”

One cover wraps both. Write the length and width, such as 31 1/2 x 78 3/4 in (80 x 200 cm), and the combined height of the two together.

Measure your own. Hemnes mattress sizes vary by country, so a catalog number may not be yours. The Hemnes measuring Pattern shows where the tape goes, and Hemnes daybed covers shows the finished fit. What does your tape say?

Exact numbers. The workshop's margin. A smooth top.

Measuring once, properly

  • Length along the top, end to end
  • Width across the top, side to side
  • Height at the side, both mattresses together if stacked
  • Each number as measured, not rounded up

A fitted mattress cover already has its seam and fit allowance built into the cutting, so an extra inch from the buyer only makes it loose.

Buyer questions

  1. A common question

    I want the daybed cover tight. Should I add a little to the mattress size?

    The workshop's answer

    No. Give the exact measurements, for example 74 x 37 x 7 in. Padding them makes the cover slightly loose, which is where crinkles come from; the sewing allowances are added in the workshop so the cover comes out snug and smooth.

  2. A common question

    Will the Hemnes mattress cover fit both stacked mattresses?

    The workshop's answer

    Yes, it wraps both. Write the length and width, such as 31½ x 78¾ in (80 x 200 cm), plus the combined height in personalization, and measure your own, because Hemnes sizes vary by country. No added leeway: the fit allowance is built into the cutting.

  3. A common question

    Can you make a bench cushion to fit an IKEA Besta?

    The workshop's answer

    Yes. Choose the closest option, e.g. 15 3/4 x 71 in (40 x 180 cm) for a 71 x 16 in (180 x 41 cm) Besta, and write your exact size. Custom thickness such as 2 3/4 in (7 cm) and matching or contrast piping are available.

  4. A common question

    Can you make a replacement cover for an IKEA sofa like the Friheten?

    The workshop's answer

    Fitted slipcovers for IKEA sofas like the Friheten aren't made. Seat cushions and backrests are, including a set of 2 backrests, 2 armrests and a mattress cover that turns an IKEA sofa bed into a lounge.

Questions buyers ask next

Why does a slightly large cover crinkle?

Because the extra fabric has nowhere to go. When a buyer's padding is added on top of the allowance already cut in, the cover sits loose on the mattress and the surplus shows as crinkles. Exact numbers keep it smooth.

Do I measure the mattress or the daybed frame?

The mattress. The cover wraps the mattress, so its length, width and thickness are the numbers that count. With two stacked mattresses, measure their combined height and write it beside the length and width.

Will the mattress be hard to get into an exact-size cover?

No. The cover is cut slightly larger than your numbers so the mattress goes in easily. That margin is built in by the workshop, which is exactly why you don't add one of your own.
