Let's face it. As populations around the world increase, the space for us to swim decreases. If you do not own an acre of land, you would most likely be destined to head to the nearest community pool to partake in water activities.
For $1400 USD, you can enjoy a swimming pool in your room! (Water bed anybody?)
How it works is you fill up the pool with 1500 gallons of water (that's about 5678 litres), attach yourself to the harness and hook on to the elastic bar that hangs overhead and start paddling away. It does sound easy to set up and to use.
To think about it, this could actually be useful for those who might need to do water aerobics or light swimming to improve leg strength or as a form of relaxational activity. Not to mention a tan as well.
