I got the inspiration to create this multi-purpose pallet chair/stool, which can be used as a gardener kneeling bench when you flip it up side down and just add a kneeling pad (In my case I just use a white foam which was from a furniture packaging, it's waterproof and can be removed when not in use), when I visited my local hardware store.
I love the natural colour of the pallet so I just leave it as is. This chair was actually made from all the left over wooden pallet scrap. As you can see on the pictures, I've used a lot of screw to keep it steady. I always love things that have multi use. This chair is one of them :)
