Some kind friends recently offered us a sofa they were getting rid of. Our old one had torn covers and an exposed frame so we gladly accepted. The old one was a sofa bed so I took out the mechanism to make it easier to take to the dump. The thin mattress that folded up with it went on top of curved wooden slats. Joel and I took a look at them and both said, "skis!".
However after a bit more thought skis weren't that practical but we did make a sledge out of them and an old chair. We made a sledge a couple of years ago out of fence post, but it was useless. We're hoping that this varnished, curved wood will go well.
