Mila, there's a place called Bangkok Upholstery. Head on to Salwa Road going to the Industrial Area, go straight past the R/A that takes you to the fish and veg market, reach the Ain Khaled R/A and go left, (DON'T carry on towards the IA). Head straight down that road. It's near a Nissan dealership.
Still trying to get you even more details.
