The cot bed base can be adjusted to 5 different heights, so that it'ss at the same level as the double bed (although it can be 1 or 2 cm below or above, without any risk). In addition, if the cot is still not at the level of the bed using these heights, the wheels can be removed. This way, you will have 5 more heights to choose from.
** (Height from the floor to the top of the mattress)
