One of my garden benches sags when you sit on it and feels like it's going to collapse underneath you. That was enough of an excuse to buy a patio glider on sale at the nearby lumberyard.
I love gliders, even more than rocking chairs. I suppose it's that calming vestibular motion.
After we replaced the creaky bench, we took a good look at it and realized the center cross-support, underneath the seat, had rotted out, but could be salvaged by sistering-up adjacent little boards of the same width and nailing everything together.
"Our bodies are of the nature to age," and so is our garden furniture. One neighbor had a hip replacement last fall, and another friend is having a knee replacement on June 8.
This old garden bench just needs a "hip" replacement, and it will be good for several more years.
