One thing that I like is finding fun surprises at the hardware store. When I came across this I envisioned this:
The project took a couple of hours (if you ignore stain drying time) and cost about 150 dollars (once you include a few accessories I added in.
The table was 80 dollars.
The padding was 10 dollars.
The fabric was 30 dollars
Then I bought some metal pipes for about 30 dollars.
The process was:
First the table had to be cut down a little, my lovely wife was not tall enough to bend over the prefabricated height.
Then I reattached the bottom support and added foam padding.
After that, I added marine vinyl and five anchor points on both long sides as well as some at the ends.
I also added some piping to allow me to restrain the hands beyond the bed and the legs in the air.
The combination opens up a lot of options to expand playtime.
The last bit is a part I have not picked up yet, a crank to stretch my wife out on; turning the bench into a midevil rack.
