If the light stands aren't stable and stiff enough, floor lamps or tripods might be.
I doubt any of those would solve the problem. Here's the situation I found on my first try with the fishing line; I began building the scene by first constructing the scaffolding with lines. I placed five sets (looped around two light weight light stands) about two inches apart. When I placed the bottom bun that line naturally sagged. I then placed the meat, which also sagged fairly equally. So far, so good. I thought I was in the clear. The cheese, being denser, caused greater sag so that required moving the line up. This is when I started noticing issues. As I had built the scaffold, each successive rung added more tension on the stand, causing a slight inward bowing to the lightweight stands (about 3 feet apart touching the sides of my table). Shifting that rung up made it slightly but discernibly looser. While it may seem like a very minor shift, with the stretch inherent in nylon fishing line it was enough to cause an increase in the sag, requiring to adjust upward even more which started a bit of a chain reaction. the next level (the lettuce) was lighter and therefor had to be adjusted downward which ran into the lines below it at the pole sides. So in actuality to get the lettuce visually lower (since we are viewing from a low camera perspective) that rung needed to be below the rung for the cheese because of the weight differences.
I was able to flub it for a while but when I added the tomatoes the whole thing really started to transmit movement and the "hammock" effect kept disturbing things below it and I ended up finally giving up. So you see, it's not all just about getting enough tension on the rungs but also being able to compensate for the different weights of each element while maintaining the stability of the entire structure. Steel wire allowed for a more stable rig and also allowed me to micro adjust the tensions as the rungs moved up and down (yes, weight still affects steel wire, though not as much).
I think maybe higher tensile strength wire would work better since it wouldn't sag as much. Something to consider down the road.
