Thick foam for settee cushions

Does anyone know where I can buy foam from to replace the seats on my settee

From a previous post:

Montesinos, passing through montesinos Tabac shop on left hand side. Go past and take next left. Small pedestrian alley way. On right hand side is an upholstery repair shop and the English lady was very helpful when we were in there couple weeks ago.
Sorry didn’t get the name but easy to find.

I think you can order foam pieces from the furnishings/linen shop next to Laurels restaurant in Quesada.

Thanks for the contacts
