Beds get all the attention, but daytime accidents land on car seats, sofas and the armchair just as often, and those are harder to clean and dearer to replace. The simplest fix is a washable absorbent pad on whatever your child sits on for long stretches, plus a proper waterproof cover for anything you cannot easily wash.
The same washable bed pads that protect a bed work beautifully on a sofa or a car seat. They have a soft top that wicks the wet away and a waterproof backing that stops it reaching the cushion. Folded to fit, they are barely noticeable, and when there is an accident you lift the pad rather than scrubbing upholstery.
Car seats
For the car, you have two sensible choices. A purpose-made waterproof car-seat protector straps over the seat and is the tidiest option if accidents in the car are regular. For the occasional wet, a folded washable pad on the seat does the job and comes straight out afterwards. Either way, keep a spare pad and a pack of wipes in the boot.
Sofas and armchairs
A washable pad in a colour close to your sofa, or slipped under a throw, vanishes into the room. That discretion matters: an older child does not want a visible “accident mat” announcing things to visitors. For a chair they use a lot, a pad with tuck-in flaps stays put better than a flat one.
Wheelchairs and special seating
If your child uses a wheelchair or supportive seating, the same principle holds but fit is everything; a pad that shifts is no use. Shaped, non-slip washable pads exist for exactly this, and an occupational therapist can point you to the right one for the chair.
Cleaning up when it happens
For the cushion or seat itself, blot rather than rub, then treat it the way you would a mattress. Plain detergent rarely shifts the smell on its own; the trick is the same as for bedding, and I have set it out in which washing products actually remove urine smell. The full step-by-step for a soaked surface is in how to clean a mattress after bedwetting; it works just as well on a sofa cushion.
Common questions
Is there a special car-seat protector for accidents?
There are purpose-made waterproof car-seat protectors, and they are worth it if accidents in the car are regular. For the occasional wet, a folded washable bed pad on the seat does the same job and comes straight out for the wash.
Will a waterproof cover make the seat sweaty?
A cheap fully-plastic one can. Look for a cover or pad with a soft, breathable top layer and the waterproof barrier underneath; your child sits on something that feels like fabric, not a bin bag.
How do I protect a sofa without it looking obvious?
A washable absorbent pad in a colour close to the sofa, or tucked under a throw, disappears completely. Most visitors will never know it is there, which matters a great deal to an older child.
