In a playard, the bassinet has adjustors with one ends connecting to a first side of the bassinet body and the other ends to a second side of the bassinet body. The adjustors extend from the first side toward and cross a first side rail of the frame body, reaching to the bottom panel of the frame body and into the frame body, and connecting to the second side of the bassinet body. The playard includes two retainers, each mounting on the second side rail of the frame body. Pulling the adjustors brings the first side and the second side of the bassinet body to move up or down by the same distance. The bassinet can therefore maintain horizontal and be adjusted to an arbitrary height during height adjusting.
