Bad-Back Chair

Like a lot of people, I suffer from a bad back, so I have designed this, it helps me.
The back is curved and the strutts at the back support the lower back beutifully, I find that after a few hours of gardening a few minutes sitting here helps my back, I am sure it will help you to.
I also make a 'bad-back bench', this looks rather strange in the picture because each of the three sectons are curved which makes it very difficult to photograph, the centre table is removable.
