Can training tables double as conference tables?

Yes — three 72" × 30" tables ganged end-to-end create a workable 18-person conference setup. Seams will be visible but acceptable in informal settings. This is the core use case for flip-top nesting tables in multi-use rooms. At OfficeFurniture2go.com, we configure dual-use rooms regularly — call 1-800-460-0858.
