Coming from sihoo m57 na nasiraan ng base tinapon ko na ang hirap tangalin nung base from the chair. Kakabili ko lang sa o

Had a non-pro version. Build quality is good but the seat was too deep (can't lean back while feet touch the floor) so it encouraged me to slouch. After a few years, I got a different Sihoo chair that's much more ergonomic for me. Try it irl muna, no chair is one-size fits all.
