Visit the MIDHILL showroom at the Lecong Furniture Centre in Foshan, China, by appointment — two working days evaluates a shortlist, five days reaches a full specification. Locally, most sellers operate showroom-only at Tai Seng or Sungei Kadut. Always bring your floor plan and lift dimensions so staff can confirm access before you commit.
