At first use this product may appear a little 'flimsy' but if adequate care is exercised in its use, it is quite safe enough. Because of the fact that it is made of light aluminum, it tends to be a bit shaky, but is in actual fact quite sturdy. The arms are made in such a way that they can swivel to each side if necessary for use by able people who do not need to rely on support when using the seat. Adjustment and fitting to the toilet bowl is very easy and only a screwdriver is needed. Well worth the money for those who are disabled in some way.
