Comment: Floor monuments (Score 1) 235
Your best bet would be floor monuments that enclose power receptacles, and if you wanted you could put network jacks too. Of course, this is only available if you have a floor that can handle this installation, so it may not be for everyone.
It's very unlikely that furniture manufacturers will ever want to wire up their products. As you stated, the fire hazards could be a disaster. If the furniture is sold worldwide, it's also unlikely they'd want to deal with the hassles of the various different voltages and regulatory approvals. They're much more comfortable with you stringing your power adapters through the couch and taking all the liability off them.
