How can I keep vertical lines straight when shooting a tabletop scene from a higher angle?

I’m photographing furniture or objects on a table from an elevated viewpoint. I’d like to see more of the top surfaces by shooting from above, but I also want the walls and furniture in the background to keep straight vertical lines instead of converging. Can this be fixed in Photoshop/Lightroom, or do I need a tilt-shift lens?

You can do perspective correction in PS, an easy way is for example via Camera Raw, or the Distort/Lens Correction filter.
Another method to retain straight verticals while shooting is to shoot with a wide FoV and keep your lens pointed horizontally. Your object will be in the lower part of the image,but you can crop that later (that's why you need the wide FoV). The trick is to not point your camera down to center the chair. (this is basically what a shift lens does, it just saves you the cropping step)

Yes—this can usually be corrected in software, and you do not necessarily need a tilt-shift lens.
The key is perspective: if you tilt the camera downward, vertical lines in the background will converge. To keep them straight in-camera, keep the camera level and use a wider field of view so the subject sits lower in the frame, then crop later. That’s essentially what a shift lens helps you do optically.
If you already have the shot, Photoshop, Camera Raw, and Lightroom all offer perspective/lens correction tools that can straighten verticals. Dedicated perspective-correction software can do this too.
The tradeoff with software correction is that you usually lose some of the frame and effective resolution because the image must be stretched and cropped. So leave extra space around the subject when shooting if you plan to correct perspective afterward.
A tilt-shift lens is the optical solution. Its main advantage is preserving more of the original frame and sensor resolution while correcting perspective in-camera. It’s useful, but not required for many situations.
