When buying a moses basket stand always make sure it complies with British Safety Standards. This is especially important when you are purchasing one from eBay, which may be second hand. The legs of the moses basket stand should securely lock so there is no risk of it collapsing when you place your baby in it. Rocking moses basket stands should be carefully designed so there is a limit on how far it can be rocked so it cannot become unbalanced. Buy from a reputable retailer and try to buy a well known brand so you know it is complying with modern standards.
Never place the moses basket on a raised surface other than your stand. This includes chairs and beds.
