Getting wee smells out of sofa fabric

[Hunstanton]

Has anyone got any tips for me on how to get urine stains/smells out of fabric?
My nephew wet himself on my fabric sofa bed and I can't remove the cushion to wash it or dry it separately.
I presume this must've happened to lots of you.
I just sprayed it with antibacterial spray and rubbed vigorously but I can still get a smell and I think it's sunk into the spongey material of the sofa.
Any tips?

Hi. Bicarbonate of soda mixed with water i brilliant for getting out smells. My son spilt a whole glass of milk on the carpet and milk stinks once it's been spilt. I looked for tips on internet and bicarbonate of soda with water worked to get rid of the smell xxx

I find vinegar better for wee smells.

And if it's a removable cushion, get it out in the sunshine if you have any.
