Floatation Centre The Floatworks has revealed the i-sopod, a new sensory relaxation device designed for commercial use.

Based on three years of research and development, the i-sopod can be produced in a range of customised colours.

Containing 1,000 litres of water and 500kg of Epsom salts, the water and air inside are heated to skin's temperature, 35.5C, so users can't work out when their body is in contact with the water.

A scrolling interior light display can be used, accompanied by soft music, or silence.
