Lay the Bed of Nails pillow on the floor or a mattress and slowly lower yourself onto it. Lay a sheet over the pillow until your skin gets used to the spikes. Initially lie on the Bed of Nails pillow for 10 - 15 mins, then build up to 20 - 30mins. Use as often as you need - preferably daily.
Don't be alarmed if your skin feels warm and tingly, and it's perfectly safe to fall asleep for a while. If you are uncertain, always consult your doctor. Keep away from children 5 years of age and younger
Leaning against it (rather than laying on top of the mat and pillow) is a lighter way to use Bed of Nails while you acclimatise (you put less weight on the spikes when you do). Place the mat/pillow at the back of your sofa, bed or armchair to experience the benefits while building up your tolerance.
