If urine has soaked into the filling, cleaning does not reach it, and the smell may stay or come back. One side of a single mattress costs from €30, of a double from €45, and smell treatment is extra, from €15. Send a photo and say how old the stain is.
What to do with fresh urine on a mattress
- Remove the bedding Check how far the liquid has got, including on the cover and mattress topper.
- Blot, do not rub Use a clean, absorbent cloth or paper to blot gently, without rubbing, and change it until no more liquid comes up.
- Only a little cool water If needed, lightly dampen the cloth in cool or lukewarm water. Do not soak the mattress, because liquid may reach the filling.
- No heat Hot water, a hairdryer and a heater may set the stain. Chlorine bleach may change the colour of the fabric.
- Air it Let the mattress air-dry. If the stain is small and fresh, that is often enough.
Why urine in a mattress is harder to deal with than on a hard surface
Foam holds liquid well and is hard to dry, and too much water is exactly what may damage its structure or leave moisture in the core. So urine in a mattress cannot simply be rinsed out: the more water, the deeper it carries the problem. In a spring mattress, moisture may also cause rust.
The smell tends to take up more space than the visible stain. Veterinary sources on cat urine say the smell area may be up to three times larger than the stain. So it matters to say how much liquid there was and how many times it happened, not just to show the stain.

Child, adult or animal
- Child: a one-off accident is usually easier, but a repeated stain in one place is a different job. More: child's urine on a mattress and children's mattress cleaning.
- Adult: if the stains appeared during an illness, see the page on mattress cleaning after illness.
- Cat: cat urine has an especially sharp smell. Veterinary sources mention enzyme cleaning products, but even with these the smell may stay. If the cat does this repeatedly, consult a vet first.
- Dog: in the form, say how many times it happened and how old the stain is.
What to expect from cleaning
Usually comes out
- a fresher urine stain on the fabric
- the edge of a stain, if it is not old
- some of the smell from the surface
May stay
- a smell, if urine has soaked into the filling
- a smell that comes back after some time
- a yellow shadow from an old stain
- mould, if the mattress has been damp for a long time
International Cat Care advises throwing away heavily soiled fabric if possible, because even after cleaning it may attract the cat. No source gives an exact limit for foam, so we do not name a figure. To be honest: after repeated accidents in one place, a mattress sometimes simply has to be replaced.
How much mattress cleaning after urine costs
Single mattress from €30, double from €45 (one side), second side +50%. Smell treatment is extra, from €15, and the specialist will tell you whether it is worth ordering. The price depends on size, fabric, how dirty it is, smell and distance, and we agree it before the work.
The minimum order is €45: if the total is lower, you pay €45. Travel is included in Riga and up to about 15 km outside Riga; further out it is from €10. All prices are on the prices page.
