The Conall natural mini portable folding crib is a compact folding crib that has stationery side rails, a one position mattress support, and solid hardwood construction. The built-in pocket feature allows the mattress to be stored in the folded crib. The heavy-duty ball bearing casters, two of which lock, make it easy to move from room to room or into its storage space. The arched end panels add elegance to your daycare center, hotel room, or home and when nap time is over, the crib is easily folded for storage. Designed and built with the rigors of commercial use in mind, but it is also perfect for use where space is at a premium. Plastic teething rails are installed on both fixed side rails. This mini folding crib includes a 24" x 38" x 3" thick foam mattress. Customer assembly required. This crib meets the Mandatory CPSC 16 CFR 1220 regulations for non-full-size cribs as well as the ASTM 2710 commercial crib regulations that are required for the rigors of a day care or other commercial environments.
