When folding, all you need to do is pull the levers on both sides of the frame towards you. Thanks to the safety mechanism, the frame will not unfold by itself and you can easily move it. You do not have to unfasten the stroller - you can fold the stroller with it.
After folding, you can detach the wheels and axles of the trolley, which will allow you to store the frame even in a wardrobe or transport it in a small trunk. You can also remove the front wheels easily - just press the button above the wheels.
If you want to unfold the stroller - remove the safety lock and, holding the handle, pull it up until the locking mechanisms engage.
