In both ends of the baby lift, there are flexible drawstrings with stoppers, which can be untightened and thereby transforming the lift to a play mat – you can also use these strings to simply expand the lift, if needed. We have added a cover for the strings in both ends, to increase the safety of the lift, so that you can prevent the strings from falling into the lift. For safety reasons, we advise you to make sure the strings are completely tightened, and the covers are closed, when using the lift to carry the baby from one destination to another.
