Mini/Portable Non-folding Wooden Window Crib. Simply arched end panels add elegance and charm and provide a cozy sleep environment for little ones. Clear acrylic panels at each end of the crib allow a caretaker to watch little ones while they sleep or play in the cozy wooden window crib. Three position adjustable mattress height. Heavy duty ball bearing casters (two locking) are attached to the legs by a Chicago bolt system through the leg post instead of the leg bottom. This is not only a stronger system but also eliminates the danger of exposed bolt threads. Includes a deluxe 24" x 38" x 3” mattress. Add strength and sturdiness to this crib for a fire drill situation with the additional purchase of WC-504-EVA evacuation frame. Bilingual instructions in English and Spanish.
