Creases in a New Sofa Cover? Check This Before You Steam or Iron

Unpack the whole cover before deciding what needs fixing

Choose a clean, dry space large enough to open the piece without dragging it across the floor. Keep the packaging, labels and any fitting sheet together while you work.

1. Open and inspect each piece. Note which side faces out and where the seams, edging or fastenings sit. Do not assume that every rectangle in a multi-piece order belongs on a seat.
2. Take a quick photo before fitting. Include the whole piece so a close-up of a line has some context. If anything appears torn, snagged or otherwise changed, photograph that separately.
3. Find the product instructions. Check the label attached to the cover and any directions supplied with that exact item. Keep the underlying couch's care information separate.

If several pieces arrived together, our guide to sofa cover pieces can help you plan the layout. It cannot identify an unlabelled piece on its own; compare it with your order and fitting sheet.

Is it a packing fold, a fitting wrinkle or a changed-looking area?

Use the descriptions below to decide what to check next. They are observations, not a way to diagnose the fabric from its appearance.

On a phone, swipe the table to see each column.

A change in shade may raise a separate question about how the fabric catches the light. Do not assume every visible line needs pressing.

Check the dry fit before adding heat or moisture

Follow the supplied fitting sequence, using the seams and edges as reference points. For separate pieces, place each one on its intended area before deciding how much fabric should hang over an edge. For a shaped cover, confirm the front and back rather than stretching it until the outline looks right.

Look across the sofa as well as at the crease. Is one side pulled tight while the other has a large fold? Is the piece sitting diagonally? Has loose material collected at a junction? Correct only what the fitting instructions allow, then compare the area with your unpacking photo.

This is a layout check, not a promise that fitting will remove every line. Do not add weights or pull hard on seams to flatten the fabric. If the cover will not fit as directed, use the fit troubleshooting guide or ask about the size and shape before attempting a finishing treatment.

Read ironing and steaming permissions separately

GINETEX, the textile-care labelling association, says ironing temperature should be selected from the care label, rather than the fibre content. Its guidance distinguishes low-temperature ironing without steam from other ironing processes and warns that some articles must not be ironed. GINETEX's ironing-care guidance

That matters when a label says “polyester”, “cotton” or “linen”: the name alone is not a finishing instruction. Nor does permission to wash tell you which heat treatment is allowed afterwards.

Dry ironing and steaming are not interchangeable. As one manufacturer-specific example, Sunbrella's upholstery guidance allows a particular dry-ironing approach for wrinkles while explicitly ruling out a steamer or steam setting. That example does not authorise either method on your cover.

Check three things before proceeding: the instructions identify your exact cover; they permit the proposed method; and your appliance instructions explain how to carry it out. If the care information is missing, unclear or contradictory, get written clarification. Start with the Sofa Decor care library and the product's supplied directions.

If a finishing method is permitted, follow the complete directions

Keep the cover instructions and appliance manual beside you. Check the specified setting, which face to work on, whether the cover must be removed, and any directions for a pressing cloth or concealed-area check. A method described for a loose cover on an ironing surface should not be improvised on the fitted sofa.

If an instruction leaves something unresolved, ask before starting. Do not substitute a hairdryer, a bathroom full of steam or a hotter setting because the first result is disappointing. These are different treatments, not automatic next steps.

When the permitted process is complete, follow its cooling or drying directions before refitting and reassessing. A remaining line is useful information for the supplier; it does not establish that more heat is needed.

Make a persistent line easier to assess

If you are unsure about a new cover, send a whole-piece photo, a clear close-up and a readable care-label photo. Include the product name, selected size, where the line sits and whether it was visible straight out of the packaging.

Describe what you have actually tried: “unfolded and fitted only” is helpful, as are the details of any authorised finishing method already used. Keep the original photos without filters.

A useful question is: “This line remains after arranging the cover as instructed. Is there a finishing method approved for this exact item, or would you like to assess it first?” You do not have to guess how long to wait. If the supplier recommends allowing time after unpacking, ask what to expect for this item and when to follow up.

Choose a cover whose fitting and care routine suits your lounge

When comparing another cover, look at its format as well as its colour. A loose throw, separate seat pieces and a shaped slipcover involve different arrangements. Measure the areas you want to cover, check what each option includes and read its care instructions before ordering.

Arden is one loose-throw option to consider for this kind of layout. Its gallery shows appearance and styling; it does not establish ironing permission or promise a crease-free finish.
