About floatation

At Zero Gravity we are committed to promoting well-being, relaxation, and healing, through floatation therapy.

So, what is floating?

Floatation Therapy is essentially a method of achieving deep relaxation by spending an hour or more lying quietly in darkness, suspended in a warm solution of Epsom salt.  It is like no other experience on Earth and many describe as like floating though outer space. The reduction in sensory input causes our brainwaves to slow down and allow us to drift into a meditative theta state.

The most common reports are profound peace and relaxation, a feeling calmness, a reduction of stress, deep concentration and creativity, and reduction of physical pain and tension.

About our float tanks

We use I-Sopod float tanks,  designed and built in the UK. The i-sopod is one of the most advanced float tanks in the world, utilising a powerful pump and the latest filtration technologies including a 1micron filter (around 100 times small than a human hair), a germicidal UV light and automatic H2O2 dosing.

At 8ft 6 long by 5ft 6 wide, i-sopods are one of the largest tanks on the market allowing you to really spready out and get comfortable in the tank, and the 550kg of Epsom Salt dissolved in 1000 Litres of water helps you float effortlessly!


Who we are

Simon Preedy 

Simon originally floated to help him wind down in the evenings and improve sleep, but over time he came to see it as a powerful tool for self-development and meditation. His main goal is now sharing these benefits with others! Outside the tank Simon loves practicing Jiu Jitsu, yoga, running and hiking in the mountains.



Chris Henson

Chris initially floated to help with back pain, but as he floated more regularly, he found he was able to maintain the tranquillity from his floats in everyday life. When he’s not floating, Chris can often be found tinkering with his gaming PC.


Graeme Poston 

Graeme is a retired surgeon with an international reputation, based in Liverpool, who after nearly 40 years standing bent over at the operating table developed ‘surgeon’s’ neck, with chronic pain and tingling/numbness in both arms. Initially, he went to Simon for deep tissue massage to his neck to keep him operating, but Simon persuaded him to try floating at another Manchester float spa which resulted in Graeme’s neck being pain free for several days afterwards. Graeme now floats every week and continues to benefit from the therapy on a regular basis.

Kiera Kelly

Kiera enjoys longer 3-hour floats so she can fully unwind, meditate, and get some well-deserved sleep. Apart from floating Kiera loves swimming and attending a variety of classes (Functional Fitness, Pilates, Zumba etc) at her local gym.

The science behind floating

The concept of Floatation Therapy is based on the theory that around 90% of the brains workload is caused by the effects of our environmental stimulation; gravity, temperature, touch, light, sound.  Even when sleeping – the mind is receiving signals from those parts of the body that are touching the bed & covers, temperature on skin, sounds & gravity.
