The mats are 600mm x 600mm x 12mm deep. With four mats to a zip pack an area of 120cm x 120cm can be covered. The interlock holds the mats securely together - no matter how hard baby kicks!
Due to their ability not to absorb any liquid, along with being resistant to household cleaners, they are easily cleaned and able to be kept hygienic. They may even be washed in bleach (all cleaners should be well rinsed off with water). Their light weight allows easy handling.  

Could be used to cover a complete floor in a nursery.

The mats have an extended life: when the children grow out of them they can be used in the garage or garden as an exercise mat, as well as many other potential uses.
