Recently, while visiting friends, we noticed that they had an immaculate house despite having 3 kids under the age of 4. How is that even possible? We had long given in to the idea of not having nice things until our youngest is about 7.
If your fabric chairs are already gross, remove the fabric and wash. Then cover with vinyl. Worst case scenario is that the fabric won't come clean in which case you spend another $4.00 on new fabric.
This is so easy, it barely needs a tutorial. Just flip your chair upside down and see how the fabric seat is attached. In this case (and all Ikea chairs) there are 4 screws that connect the seat to the chair. Unscrew those and remove the seat. The fabric is attached by an elastic string. If you want to wash it, peel it off and throw it in the wash. If it's still new and clean, grab your vinyl (we didn't even measure, just eyeballed it- 1 yard of vinyl did 4 chairs with quite a bit extra left over) and fold it around the seat, stapling the edges to the wooden back of the seat.
