I've never seen a box spring without the material before. That definitely had to be a chore to get it to that point! It gives me a few ideas, though I don't know how good or practical they'd be.
- My favorite idea is to hang it from the ceiling of an unfinished basement or a shed with the metal side facing down. (Or even attached to, or resting against, a wall since it would have airflow.) You can use it to hang bundles of flowers, herbs, etc., to dry. If you're about to get your first hard frost and need to harvest the last of the produce that's outside so the frost doesn't kill it, I know some folks will pull up their entire pepper plant and hang them upside down to give the remaining peppers more time to develop. Tomatoes, too.
To save on the weight of the frame, you can always cut away all the wood except for the outside of the frame. Or cut away all the wood altogether.
- I can't see the inside of the frame well
enough to know if this would work, but maybe you could lay boards across the wires and use it as a shelf in a shed or garage. You might even be able to inset it into a wall so it's recessed.
- You could frame the outside of the frame with wood and use it as a raised
garden bed, complete with sections for different flowers, herbs or veggies. (Removing a piece of wood or two would make a section or two bigger if needed.
- If you remove the wood and just use the metal frame, you could use it as a
trellis for plants that would quickly cover it so the frame wasn't visible.
- If you cover the outside of the frame in
greenhouse plastic, could you use it as a
greenhouse cover over seedlings you planted in the garden? It would give them the benefits of a greenhouse and protect the seeds from critters. Maybe the fall squash and pumpkin seeds that squirrels like to dig up?
I'm sure these are basic ideas that already occurred to you, though. I'd be interested to know what you eventually do with it. After all that work, it'd be a shame to just throw it away!
