Little Shop of Horrors

So, okay, yesterday, I hacked off some of the leaf fronds to ease up on the weight, it wasn't enough. Tom is getting too big. It's listing and I fear for my plant. On one hand, I consider hacking off the top half to let the tomatoes that are present grow up and ripen - On the other hand, I'm greedy and want to see more of those blossoms turn into tomatoes. What to do? You can see some of my Grandma Engineering - pony tail bands turned bungee cords to support to chair and curtain rod. It is not enough. DH suggested cutting a hole in the seat of the chair for the pot and 2x4's attached to the chair seat to trellis the rapidly growing plant. I looked for a cheap set-up on Amazon. I really don't want a broken chair (and it would be) and 2x4's in my bedroom - no matter how bad I want those BLTs!

 I would ask you what you would do in my situation, but I believe you wouldn't even do such a thing in your bedroom. Am I wrong?
