Is it on a crawl space? Floor outlets would be an easy add-on then.

Even if it is on a slab you can cut in a trench for a floor box. It's not even that onerous if they haven't put the finish floor in.

A floor outlet is a good idea, they can prevent trip hazards! but there should be a wall receptacle nearby, unless her chair is in the middle of the room. I like to make sure there are several on each wall (closer together than code requires).

I agree that the best solution would be to add a floor outlet--easy if it's a crawlspace, and still possible if it's a slab, IF the finished floor hasn't been installed yet.

If it's too late, another option is a cordless, battery operated lamp from modernlantern.com. I have no association with the company beyond being a happy customer. Yes, the lamps are expensive, but they solve the problem. I use mine in my great room. It's on approximately 2 hours every day, and I have to recharge the battery once a week; it takes about 3 hours to fully charge.

Edited to add: the cordless lamp wouldn't solve the heating pad problem, but a good old fashioned hot water bottle might help if the outlet isn't feasible.

100% not putting an outlet in our floor in the living room! Do it if you can. The different options for cordless are also so weak. I’ve yet to find a great one

In the past I have called for wire(s) to be coiled under the floor of the living room for floor outlets locations to be determined after the furniture has been moved in and final layout determined.

Living rooms on a slab takes longer.

@stax I was not able to find a cordless arc lamp at all. There were smaller desk type lamps with batteries but not suitable in our space.

Mark was hoping to avoid that one other than at a camp out! 😂
