Buy a good one la. Sofa not easy to replace and it's actually one of the most important furniture in ur house. Make big impression on guest, you also will spend significant amount of time sitting on it also.

One thing i most beh tahan when stay AirBNB is they always buy cheap ass sofa. super not nice to sit. can feel the supporting beam/join whatever u call it. My own sofa set RM5000+ for 2+2+1 i am using for close to 20 years liao still kuat no sink. The difference with cheapass one is like day and night. My only regret is no buy extra cover to swap around when i wash.
