Used in healing practices for centuries, modern versions of these spiky mats are increasingly popular, and many people find them invaluable. Here’s what the science says

Ever since Keith, 39, from Kansas, was in a car accident in 2023, he has lived with “pretty much constant mid-back and shoulder pain”. Over-the-counter treatments didn’t touch the sides and he didn’t want to resort to opiates. “Having exhausted everything there was solid science for with no satisfaction, I delved into acupressure,” he says. He bought an acupressure mat made of lightly padded fabric, studded all over with tiny plastic spikes, to lay his back on, and was surprised to find that it actually helped.

Acupressure mats, also known as Shakti mats, are inspired by the beds of nails that Indian gurus used for meditation and healing more than 1,000 years ago. While today’s mats have the nonthreatening sheen of a luxury wellbeing product, the spikes are no joke. In fact, the internet serves up a plethora of images of flaming, dented backs after their use – although you’re unlikely to seriously injure yourself using them. While the mats have been widely available for more than a decade, there has been a recent surge in mainstream interest. You may have seen them heavily advertised on your social media feed, the most prominent brand being Shakti Mat, made in India and costing up to £99 for the premium model. But Amazon is full of acupressure mats and pillows – Lidl recently stocked a mat and pillow combo for a tenner. Yet there is still no compelling evidence that they relieve stress, pain and sleep problems, or help with any other unmet health needs.
