Back Stretching Chair (Dibden SO45)

Fold up chair which flips backwards so that your back gets a supported backwards stretch.
Is like a camping chair type of construction though much sturdier. Pristine condition and I still have original box.
Needs space, as you'll end up with legs stretched out in front and arms over head. And hips up in the air.
Works fantastically on your bad back. (Obviously depending what your back problem is...) I've moved house and can't keep it.
