I found a set of cast iron box springs, round the corner to where we live. Someone was throwing them out. Took them home and decided to use them as the top part of an arbour at the foot of our garden steps.
Arbour Made With Recycled Box Springs
We purchased 4 x H4 treated pine posts and oiled them with a 50/50 mix of raw linseed oil and mineral turpentine. Then cut slots into the tops of each post for the box spring base to sit into.
My hubby dug 4 post holes after measuring up the box springs base to ensure the posts were positioned correctly and that the box springs base would sit neatly into the slots. He used two bags of quick set concrete per post hole.
A friend helped to hoist the box springs atop the posts. They were heavy being cast iron. It took a bit of jiggling to get them to fit into the cut slots and a little bit of adjustment was made to the slots to accommodate them.
Once the springs were safely in place, we added some colourful beakers which we inserted into the springs so that the sunshine would come through the coloured beakers and look pretty.
We have since added trellis to the sides of the posts and put a climbing rose in a large planter on one side and a star jasmine climbing plant in a planter on the other side. Hopefully when they grow in, they will meet at the top in the middle somewhere.
