TL;DR
The upholstery cleaning tag is almost always in one of six places: under a seat cushion on the deck, on the underside of the cushion itself, stapled to the frame under the piece, inside the skirt hem, on the back panel, or on a zipper tape. Check them in that order and photograph the tag once you find it.
Where Is the Cleaning Tag on a Sofa?
On most sofas the cleaning tag is sewn to the deck -- the platform under the seat cushions -- near a back or side corner. Lift every cushion and look along all four edges of the deck before moving on. If it is not there, the underside of the cushion cover is the next most likely spot.
That two-place check finds the tag on the majority of residential upholstered furniture. Everything below is for the pieces that hide it better.
The Six Places to Check, in Order
1. The deck under the seat cushions. Pull all cushions out. Run a hand along the deck edges, especially the back corners where a tag is easy to miss against the fabric.
2. The underside of the seat cushion. Flip each cushion. Tags often sit near the zipper end or along a boxing seam.
3. Under the piece, on the frame or dust cover. Tip the sofa forward onto its face against a wall, or lift one end. Tags get stapled to the frame rail or sewn to the black dust cover stretched across the bottom.
4. Inside the skirt hem. If the piece has a fabric skirt, lift it and check the inside face and the hem itself.
5. The back panel. On chairs and recliners, look at the outside back near the bottom, or behind a removable back cushion.
6. A zipper pull tape. Some makers print the code on the twill tape sewn into a cushion zipper.

Recliners and Sectionals Are Different
A recliner has to be opened to give up its tag. Put the footrest up and look at the inside of the leg rest, the back of the seat platform, and the outside back panel near the bottom. Some tags sit on the frame inside the mechanism cavity, which you can only reach with the chair fully extended.
Sectionals often carry a tag on only one section, usually the piece with the manufacturer label. Check the corner unit and the piece with the console first. If one section has a tag, it normally applies to the whole set, but confirm the fabric matches -- some sectionals mix a body fabric with an accent fabric on a chaise or ottoman.
Cleaning a fabric recliner covers the rest of the mechanism problem once you have the code.
Do Not Confuse the Law Label With the Cleaning Tag
Most upholstered furniture carries a law label -- the tag that says something like "do not remove under penalty of law." That tag lists the filling materials and the maker, and it is required in most states. It is not the cleaning tag, and it usually says nothing about method.
Sometimes the two are printed on the same tag, with the cleaning code as a single letter in a box or a short line reading "cleaning code: S." Read the whole tag before deciding you have found nothing.
Removing a law label is legal for the owner -- the penalty language is aimed at retailers -- but do not remove it anyway. It is often the only record of the fabric content you will ever have.
Once You Find It, Photograph It
Take a clear phone photo of the whole tag, including the fiber content line, and keep it in a folder with your other home records. Tags fade, staples pull out, and dust covers tear. A photo survives all three.
If you are about to buy upholstered furniture, ask for the code before the sale rather than after delivery. It is a legitimate question, and the answer changes how much the piece will cost to own.
What the Letter Actually Tells You
The code is a single letter and it sets a hard limit. W means water-based cleaners are safe. S means solvent only, and water will ring or shrink it. WS means either is fine. X means vacuum only, with no liquid of any kind. What the code letters mean breaks down each one and the fabrics that typically carry it.
Whatever the tag says, still test a hidden area before cleaning. Age, sun exposure, and previous cleaning attempts all change how a fabric behaves, and the tag reflects the cloth as it left the mill.
If the Tag Is Missing or Unreadable
A missing tag is common on secondhand pieces, older furniture, and anything that has been reupholstered. Reupholstered furniture is the worst case, because the new fabric may behave nothing like the original tag suggests.
What to do when there is no tag walks the safe testing sequence. The core rule is to assume the most restrictive option and prove your way down, not to assume it is washable and find out the hard way. How to clean a fabric sofa picks up from there.
FAQ
Where is the cleaning tag on a couch?
Usually sewn to the deck under the seat cushions, near a back or side corner. If it is not there, check the underside of a seat cushion, the frame or dust cover beneath the piece, the inside of the skirt, and the back panel.
Why can I not find a tag on my sofa?
Small makers and some imports skip the cleaning tag entirely, and it is often lost when a piece is reupholstered or when a dust cover tears. Secondhand furniture frequently arrives without one. Test a hidden area instead of guessing.
Is the law label the same as the cleaning tag?
No. The law label lists filling materials and the manufacturer and is required in most states. The cleaning code is a separate letter, sometimes printed on the same tag. Read the entire tag before deciding the code is missing.
Where is the tag on a recliner?
Open the chair fully and check the inside of the leg rest, the back of the seat platform, and the outside back panel near the bottom. Some recliner tags are attached to the frame inside the mechanism and only show when the chair is extended.
Does every section of a sectional have a tag?
Usually not. One section carries the tag and it normally covers the set. Confirm the fabric on every piece matches, since some sectionals pair a body fabric with a different accent fabric on a chaise or ottoman.
Can I remove the tag once I know the code?
You can, but do not. The tag is often the only record of the fiber content, and a future cleaner will want to read it. Photograph it instead and leave it attached.
When the whole floor needs it rather than one spot, professional carpet cleaning is the wider option.
Thirty seconds with a phone camera is the cheapest insurance an upholstered piece will ever get. If your tag is gone, the code is one you cannot work with at home, or the fabric is already marked, that is worth a professional look. Get a quote and we will walk you through it.
