I am trying to find out where to buy a floor cot for my baby. I saw these being used when in Italy and like the idea that when a toddler is tired he/she will be able to take him/herself off to bed when he likes rather than having to wait for an adult to decide that it is time for a sleep. I have also seen them bign used in a day care nursery in England. This is a mattress (they looked more sqaure than the normal cot matress shape) that sits inside of a wooden base on the floor. There are no bars around the wooden base becase if the toddler/baby rolls out they are just a few inchs up off he floor.
Does anyone have any clues of manufacturers or distributors?
