Last Summer I was driving past a yard sale when my spidey sense started to tingle with such intensity that I knew I would find something awesome. Sure enough, there was an incredible Haba play tent, new in the box because the woman who bought it couldn't persuade her husband to put a bolt in the ceiling.
I snatched it up at 10% of its retail price, and excitedly called my husband to tell him that we needed a bolt in our ceiling. He was quickly convinced, and we have come to realize that one little piece of hardware affords us incredible play opportunities and versatility in our family room. The Haba tent hangs instantly with a carabiner, and we frequently swap it out for the IKEA Ekorre swing (which seems to be intermittently available in the US market but is easy to find on ebay or amazon). Both items store easily and became fast family favorites. There are a few other swings and tents that we might add into the mix.
Without anything hanging from it, the eye bolt is inconspicuous, and it will be easy to remove and repair if we ever want to list our home. We chose hardware rated for much more weight than necessary and made sure it was securely anchored into a joist. That family with no holes in their ceiling is totally missing out. Homeowners should bite the bullet, while renters are wise to ask landlords for permission rather than forgiveness. Put a bolt in your ceiling!
