A bassinet includes a frame unit, two legs pivotally connected to the frame unit, a bottom plate disposed between the legs, and a lower limiting mechanism disposed on at least one of the legs. The bottom plate is detachably connected to the legs via the lower limiting mechanism. Another bassinet includes the frame unit, four of the legs pivotally connected to the frame unit and disposed angularly spaced apart from each other, an upper limiting mechanism disposed on at least one of the frame unit and the legs for limiting pivotal movement of the legs away from each other, and the bottom plate detachably connected to the legs to exert forces pushing the legs away from each other.
