The “Classic” Arteflame is modular in design. The cooktop fits with any base. This allows you to select the base you want or have multiple bases that all fit your Arteflame cooktop. The high base puts the Arteflame at 38 inches which is great for stand-up grilling. If you plan on using your Arteflame sitting down as well, the low base puts the Arteflame cook top at 18 inches which is coffee table height.
