As you can see from the image, I have no room for anything in the garage, so I told him - find something to do with that or I'm throwing it out.
A trip to Goodwill and $5 later, we had skis attached to the chair.
Because of the high centre of gravity, this chair feels very unstable, couple that with the complete lack of steering/braking and you're ready for fun on the slopes!
We took it out for a spin at a local tobogganing hill and got large numbers of 'stares of wonder'. This actually goes much faster than most toboggans and it just feels great.
I didn't include full pictures of assembly, because if you can't figure out how to bolt two skis to a chair from the picture, you probably couldn't make this with instructions either.
Have fun, and remember to play safe on the hills
