one side. No sliding side as I chose non-sliding for baby safety. It is good for you to know that the mattress is the correct size in this cot for baby safety.
Bought for our sons, the Arm's reach Co Sleeper Cot which attaches to your bed to allow baby to sleep close by but safely (also works as a portable cot). Includes canopy
also new, has air filters through the base and was always used with a mattress protector. Bought new for $120. Please don't hesitate to message with questions
