Thousands of blunt plastic points under your back. The first minute is strange, the fifth is the reason people keep one.

Mat 67 × 42 × 2.5 cm, pillow 38 × 15 × 10 cm. Cotton, ABS points and foam. Green or navy.

Lie on it for ten minutes, on the floor rather than on a bed — a soft surface absorbs the pressure and the whole effect with it. Start with a T-shirt between you and the points, then go without once you are used to it. It is the cheapest thing in this shop to leave out and actually use every day.

Delivery 6 to 15 business days from our partner warehouse.
