Looks simple enough, is simple enough, and is such a clever little invention. This clever piece of fabric rolls up into a small sausage for easy storage, even in your handbag. At any time you need to secure your baby in a sitting position, you can attach the Tamsit to most upright chairs and the baby sits happily whilst you have both hands free. Ideal for travelling, holidays or days out. Is very tough and can last another child. Up to 18 months.
