Number of base levels
The number of different levels of base installation provided in the design of the crib. This height is different for different ages. So, in the first months of life, the baby is not even able to turn over independently, the risk of falling out of the crib is minimal, and therefore at this time you can set the mattress higher, so that it was more convenient to lean over to the baby. Later, when the baby is able to roll over and then sit and stand, the mattress can be lowered to minimize the risk of falling out. The more levels of
mattress depth adjustment are provided in the design, the wider the possibilities for setting its optimal height. In addition, some cribs have a removable sidewall, which allows you to move them to the parent's bed. And the adjustment of the base allows you to maximally equalize the height of the bed and crib.
Lockable wheels
The latches are designed to
block the rotation of the wheels of the bed and prevent it from moving — for example, if a nearby baby tries to climb onto the bed or grab to stand up, the bed without latches can move, which is fraught with unpleasant consequences.
Mattress
The size of the mattress in length and width in centimeters. The standard sizes of baby mattresses are 60x120, 70x120 and 70x140; you should pay attention to these sizes if you plan to buy a mattress separately from the crib.
The length of baby cribs varies from 90 to 140 cm, with 120 cm being the most common. The smaller size means that the crib will have to be changed sooner, and the longer lengths are usually convertible cribs (refer to "Type") designed not only for babies, but also for preschoolers and schoolchildren.
The width of the mattress can vary from 40 to
70 cm, and the most common option is
60 cm, this is considered quite enough. As in the case of length, a smaller width means that the baby will become cramped in it earlier, and usually convertible models have a larger width.
All of the above does not apply to cradles (refer to "Type") — they are designed only for the smallest and are much smaller.
