If you are located in KL or PJ, you may try to contact Brother Lim Cushion. Google this and you will find them. I used their service once and not bad.

Actually, depends on your sofa. If you have good frame, the end result will be like getting a new one. Previously, I had engaged them to do one set. That was around RM1800, back in 2019. I calculated. For me to dispose (i.e. getting someone to come and remove my old) and get a new one with the same frame, it will cost me 4k and above. So, I decided to get them to do it for me. It has been 5 years and my sofa is still look like new. Nevertheless, this is your call. I don't get any commission from them.
